Improved methods for transforming Phaffia strains, transformed Phaffia strains so obtained and recombinant DNA in said methods

Technical field The present invention relates to methods for transforming Phaffia yeast, transformed Phaffia strains, as well as recombinant DNA for use therein

Background of the invention

Methods for transforming the yeast Phaffia rhodoz ma have been disclosed in European patent application 0 590 707 A 1 These methods involve incubation of protoplasts with DNA or incubation of Phaffia cells with DNA followed by lithium acetate treatment The recombinant DNA used to transform Phaffia strains with either of these methods comprised a Phaffia actm gene promoter to drive expression of the selectable marker genes coding for resistance against G418 or phleomycin The methods involve long PEG and lithium acetate incubation times and transformation frequencies are low When protoplasts are used, the transformation frequency is dependent on the quality of the protoplast suspension, making the procedure less reliable

Recently a method for transforming Phaffia strains has been reported by Adπo J L and Veiga M (July 1995, Biotechnology Techniques Vol 9, No 7, pp 509-512) With this method the transformation frequencies are in the range of 3 to 13 transformants per μg DNA, which is low A further disadvantage of the method disclosed by these authors consists in increased doubling time of the transformed cells The authors hypothesised that this may be due to interference of the autonomously replicating vector with chromosome replication Clearly, there is still a need for a reliable and efficient method of transforming Phaffia strains with foreign DNA It is an objective of the present invention to provide methods and means to achieve this It is a further objective of the invention to optimize expression of certain genes in Phaffia rhodozyma in order to make Phaffia a more suitable production host for certain valuable compounds

Detailed description of the invention

The invention provides in generalised terms a method for obtaining a transformed Phaffia strain, comprising the steps of contacting cells or protoplasts of a Phaffia strain with recombinant DNA under conditions conducive to uptake thereof, said recombinant DNA comprising a transcription promoter and a downstream sequence to be expressed which is heterologous to said transcription promoter, in operable linkage therewith, identifying Phaffia rhodozvma cells or protoplasts having obtained the said recombinant DNA in expressible form,

wherein the transcription promoter comprises a region that is found upstream of the open reading frame of a highly expressed Phaffia gene.

In order to illustrate the various ways of practicing the invention, some embodiments will be high-lighted and the meaning or scope of certain phrases will be elucidated.

The meaning of the expression recombinant DNA is well known in the art of genetic modification, meaning that a DNA molecule is provided, single or double stranded, either linear or circular, nicked or otherwise, characterised by the joining of at least two fragments of different origin. Such joining is usually, but not necessarily done in vitro. Thus, within the ambit of the claim are molecules which comprise DNA from different organisms or different genes of the same organism, or even different regions of the same gene, provided the regions are not adjacent in nature. The recombinant DNA according to the invention is characterised by a transcription promoter found upstream of an open reading frame of a highly expressed Phaffia gene, fused to a heterologous DNA sequence. With heterologous is meant 'not naturally adjacent'. Thus the heterologous DNA sequence may be from a different organisms, a different gene from the same organism, or even of the same gene as the promoter, provided that the downstream sequence has been modified, usually in vitro. Such modification may be an insertion, deletion or substitution, affecting the encoded protein and/or its entrance into the secretory pathway, and or its post-translational processing, and/or its codon usage.

The strong transcription promoter according to the invention must be in operable linkage with the heterologous downstream sequence in order to allow the transcriptional and translational machinery to recognise the starting signals. The regions upstream of open reading frames of highly expressed

Phaffia genes contain TATA-like structures which are positioned at 26 to about 40 nucleotides upstream of the cap-site; the latter roughly corresponds with the transcriptional start site. Thus in order to allow transcription of the heterologous downstream sequence to start at the right location similar distances are to be respected. It is common knowledge, however, that there is a certain tolerance in the location of the

TATA-signal relative to the transcription start site. Typically, mRNAs of the eukaryotic type contain a

5 '-untranslated leader sequence (5'-utl), which is the region spanning the transcription start site to the start of translation; this region may vary from 30 to more than 200 nucleotides. Neither the length nor the origin of the 5'-utl is very critical; preferably it will be between 30 and 200 nucleotides. It may be from the same gene as the promoter, or it may be from the gene coding for the heterologous protein. It is well known that eukaryotic genes contain signals for the termination of transcription and/or polyadenylation, downstream of the open reading frame. The location of the termination signal is variable, but will typically be between 10 and 200 nucleotides downstream from the translational stop site (the end of the open reading frame), more usually between 30 and 100 nucleotides downstream from the translational stop site. Although the choice of the transcription terminator is not critical, it is found, that the when the terminator is selected from a region downstream of a Phaffia gene, preferably of a highly expressed Phaffia gene, more preferably from the GAPDH-encoding gene, the level of expression, as well as the frequency of transformation is improved.

It was found that significant numbers of clones were obtained which could grow on very high G418 concentrations (up to, and over, 1 mg/ml). Transcription promoters according to the invention are

said to be from highly expressed genes, when they can serve to allow growth of transformed Phaffia cells, when linked to a G418 resistance gene as disclosed in the Examples, in the presence of at least 200 μg/ml, preferably more than 400, even more preferably more than 600, still more preferably more than 800 μg/ml of G418 in the growth medium Examples of such promoters are, in addition to the promoter upstream from the GAPDH-gene in Phaffia, the promoters from Phaffia genes which are homologous to highly expressed genes from other yeasts, such as Ptchia, Saccharomyces, Kluyveromvces, or fungi, such as Tnchoderma, Aspergtllus, and the like. Promoters which fulfill the requirements according to the invention, may be isolated from genomic DNA using molecular biological techniques which are, as such, all available to the person skilled in the art. The present invention provides a novel strategy for isolating strong promoters from Phaffia as follows A cDNA-library is made from Phaffia mRNA, using known methods Then for a number of clones with a cDNA insert, the DNA fragment (which represents the cDNA complement of the expressed mRNA) is sequenced As a rule all fragments represent expressed genes from Phaffia Moreover, genes that are abundantly expressed (such as the glycolytic promoters) are overrepresented in the mRNA population Thus, the number of DNA-fragments to be sequenced in order to find a highly expressed gene, is limited to less than 100, probably even less than 50 The sequencing as such is routine, and should not take more than a couple of weeks The nucleotide sequences obtained from this limited number of fragments, is subsequently compared to the known sequences stored in electronic databases such as EMBL or Geneseq If a fragment shows homology of more than 50% over a given length (preferably more than 100 basepairs) the fragment is likely to represent the Phaffia equivalent of the gene found in the electronic database In yeasts other than Phaffia, a number of highly expressed genes have been identified These genes include the glycolytic pathway genes, phosphoglucoisomerase, phosphofructokinase, phosphotπoseisomerase, phosphoglucomutase, enolase, pyruvate kinase, alcohol dehydrogenase genes (EP 120 551 , EP 0 164 556, Rosenberg S et al , 1990, Meth Enzy ol 185, 341-351 , Tuite M F 1982, EMBO J 1, 603-608, Price V et al , 1990, Meth Enzymol 185, 308-318) and the galactose regulon (Johnston, S A et al , 1987, Cell 50, 143-146) Accordingly, those Phaffia cDNA fragments that are significantly homologous to the highly expressed yeast genes (more than 40%, preferably more than 50% identity in a best match comparison over a range of more than 50, preferably more than 100 nucleotides) should be used to screen a genomic library from Phaffia, to find the corresponding gene Employing this method, 14 higly expressed RNAs from Phaffia rhodozyma have been copied into DNA, sequenced, and their (putative) open reading frames compared to a nucleic acid and amino ammo acid sequence databases It turned out that 13 out of these fourteen cD As coded for πbosomal protein genes, of which one coded simultaneously to ubiquitin, one cDNA codes for a glucose-repressed gene The isolation of the genes and the promoters usually found upstream of the coding regions of these genes is now underway, and it is anticipated that each of these transcription promoters may advantageously be used to express heterologous genes, such as carotenoid biosynthesis genes Among the genes and transcription promoters especially preferred according to this invention are the promoter found upstream of the ubiquit - πbosomal 40S protein corresponding to the cD A represented in SEQIDNO 10, the glucose-repressed cDNA represented in SEQIDNO 26, the 40S πbosomal protein S27 encoding cDNA represented in

SEQIDNO 28, the 60S πbosomal protein Plα encoding cDNA represented by SEQIDNO 30, the 60S πbosomal protein L37e encoding cDNA represented in SEQIDNO 32, the 60S πbosomal protein L27a encoding cDNA represented in SEQIDNO 34, the 60S πbosomal protein L25 encoding cDNA represented in SEQIDNO 36, the 60S πbosomal protein P2 encoding cDNA represented in s SEQIDNO 38, the 40S πbosomal protein S17A/B encoding cDNA represented in SEQIDNO 40, the 40S πbosomal protein S31 encoding cDNA represented in SEQIDNO 42, the 40S πbosomal protein S 10 encoding cDNA represented in SEQIDNO 44, the 60S πbosomal protein L37A encoding cDNA represented in SEQIDNO 46, the 60S πbosomal protein L34 encoding cDNA represented in SEQIDNO 48, or the 40S nbosomal protein SI6 encoding cD A represented in SEQIDNO 50 o Promoters from these or other highly expressed genes can be picked up by the method according to the invention using only routine skills of (a) making a cDNA library on mRNA isolated from a Phaffia strain grown under desired conditions, (b) determining (part of) the nucleotide sequence of the (partial) cDNAs obtained in step (a), (c) comparing the obtained sequence data in step (b) to known sequence data, such as that stored in electronic databases, (d) cloning putative promoter fragments is of the gene located either directly upstream of the open reading frame or directly upstream of the transcription start site of the gene corresponding to the expressed cDNA, and (e) verifying whether promoter sequences have been obtained by expressing a suitable marker, such as the G418 resistance gene, or a suitable non-selectable "reporter" sequence downstream from a fragment obtained in (d), transforming the DNA into a Phaffia rhodozyma strain and determining the level of expression of the 2o marker gene or reporter sequence of transformants A transcriptional promoter is said to be of a highly expressed gene if it is capable of making Phaffia rhodozyma cells transformed with a DNA construct comprising the said promoter linked uptream of the G418 resistance marker resistant to G418 in concentrations exceeding 200 μg per liter culture medium, preferably at least 400, more prefereably more than 600 μg/1 Especially preferred promoters are those conferring resistance against more than 800 25 μg/ml G418 in the growth medium

Optionally, the transcriptional start site may be determined of the gene corresponding to the cDNA corresponding to a highly expressed gene, prior to cloning the putative promoter sequences, this may serve to locate the transcriptional initiation site more precisely, and moreover, helps to determine the length of the 5'-non-translated leader of the gene To determine the location of the transcription start 30 site, reverse primer extension, or classical Sl-mapping may be performed, based on the knowledge of the cDNA sequence Thus the exact location of the transcription promoter can be determined without undue burden, and the isolation of a fragment upstream of the transcription start site and containing the promoter, from a hybridising genomic clone (for example a phage or cosmid) is routine Cloning the putative promoter fragment in front (upstream) of the coding region of, for example the G418-resιstance 35 gene, and transforming the gene cassette to Phaffia in order to evaluate the level of G418 resistance, and hence the level of expression of the G418-resιstance gene as a consequence of the presence of the promoter is routine

In a manner essentially as described for the isolation of other strong promoters, above, a transcription terminator may be isolated, with the proviso, that the terminator is located downstream

from the open reading frame. The transcription stop site can be determined using procedures which are essentially the same as for the determination of the transcription start site. All these procedures are well known to those of skill in the art. A useful handbook is Nucleic Acid Hybridisation, Edited by B.D. Hames & S.J. Higgins, IRL Press Ltd., 1985; or Sambrook, sub. However, it is not critical that the transcription terminator is isolated from a highly expressed Phaffia gene, as long as it is from an expressed gene.

Using recombinant DNA according to the invention wherein the open reading frame codes for reduced sensitivity against G418, a transformation frequency was obtained up to 160 transformants per μg of linear DNA, at a G418 concentration in the medium of 40 μg/ml. About 10 to 20 times as much transformed colonies were obtained with the vector according to the invention (pPR2) than with the prior art vector pGB-Ph9, disclosed in EP 0 590 707 A l (see Table 2; in the experiment of Example 7, the improvement is even more striking).

The method according to the invention calls for conditions conducive to uptake of the recombinant DNA. Such conditions have been disclosed in EP 509 707. They include but are not limited to the preparation of protoplasts using standard procedures known to those of skill in the art, and subsequent incubation with the recombinant DNA. Alternatively, Phaffia cells may be incubated overnight in the presence of LiAc and recombinant DNA. Still further alternative methods involve the use of particle acceleration. According to a preferred embodiment, the conditions conducive to uptake involve eiectroporation of recombinant DNA into Phaffia cells, such as described by Faber et al., (1994, Current Genetics 25, 305-310). Especially preferred conditions comprise eiectroporation, wherein the recombinant DNA comprises Phaffia ribosomal DNA, said recombinant DNA being in the linear form, most preferably by cleaving said recombinant DNA in the said ribosomal region. Still further preferred conditions, comprise the use of recombinant DNA in amounts of between 1 and 10 μg per 10 ⁸ cells, more preferably about 5μg recombinant DNA is used per 2x l0 ⁸ cells, which are cultivated for 16 h at 21°C.

Once cells have been transformed according to the method, identification of transformed cells may take place using any suitable technique. Thus, identification may be done by hybridisation techniques, DNA amplification techniques such a polymerase chain reaction using primers based on the recombinant DNA used, and the like. A preferred method of identifying transformed cells is one which employs selection for the recombinant DNA that comprises a gene coding for reduced sensitivity against a selective agent. A useful selective agent is G418, hygromycin, phleomycin and amdS. Genes that code for reduced sensitivity against these selective agents are well known in the art. The open reading frames of these genes may be used as the heterologous downstream sequence according to the invention, allowing selective enrichment of transformed cells, prior to identification of transformed cells. Once transformed cells have been identified they may used for further manipulation, or used directly in the production of valuable compounds, preferably in large scale fermentors.

It will be clear, that a very efficient method for transforming Phaffia strains has been disclosed. Moreover, not only the frequency of transformation is high, the expression levels of the transforming DNA is very high as well, as is illustrated by the exceptionally high resistance against

G418 of the transformed Phaffia cells when the open reading frame of the G418-resιstance gene was fused to a promoter according to the invention when compared to the G418 resistance gene under control of the actm promoter in pGB-Ph9 It is concluded, therefore, that the GAPDH-promoter is a high-level transcriptional promoter that can be suitably used in conjunction with any heterologous DNA sequence, in order to reach high expression levels thereof in Phaffia strains

It will be clear that the availability of new expression tools, in the form of the recombinant DNA according to the invention, creates a wealth of possibilities for producing new and valuable biomolecules in Phaffia

Preferably, the downstream sequence comprises an open reading frame coding for proteins of interest For example genes already present in Phaffia, such as those involved in the carotenoid pathway, may be manipulated by cloning them under control of the high-level promoters according to the invention Increased expression may change the accumulation of intermediates and/or end-products or change the pathway of β-carotene, cantaxanthin, astaxanthin and the like The overexpression of the crtB gene from Erwtnta uredovora will likely increase astaxanthin levels, as the product of this gene is involved in the rate limiting step The expression of a protein of interest may also give πse to xanthophylls not known to be naturally produced in Phaffia, such as zeaxanthin An open reading frame that may be suitably employed in such a method includes but is not limited to the one encoding the protein producing zeaxanthin (crtZ gene) obtained from Erwinia uredovora (Misawa et al 1990 J Bacteπol 172 6704-6712) Other carotenoid synthesis genes can be obtained for example from Flavobacteπum (a gram-positive bacterium), Svnechococcus (a cyanobacteπum) or Chlamydomonas or Dunaltelia (algae) Obviously, carotenoid synthesis genes of a Phaffia strain, once the genes have been isolated and cloned, are suitably cloned into a recombinant DNA according to the invention and used to modify the carotenoid content of Phaffia strains Examples of cloned carotenoid genes that can suitably be overexpressed in Phaffia, are those mentioned in Fig 8 Particularly useful is crtE from Phvcomvces blakesleanus, encoding Geranylgeranyl Diphosphate Synthase, and crtB, encoding phytoene synthase, as this step appears to be the rate-limiting step in carotenoid synthesis in Thermus thermophylus (Hoshino T et al , 1994, Journal of Fermentation and Bioengineeπng 77, No 4, 423-424) Especially preferred sources to isolate carotenoid biosynthetic genes or cDNAs from are the fungi Neurospora crassa, Blakeslea trtspora Other yeasts shown to possess cross-hybπsing species of carotenoid biosynthetic genes are Cystqfylobasidium, e g btsporidit and capttatum

Carotenoid biosynthesis genes have also been identified in plants, these plant cDNAs or genes from plants may be used as well Optionally, the codon usage of the Phaffia genes or cDNAs may be adapted to the preferred use in the host organism

Of special interest according to the present invention, are the DNA sequences coding for four different enzymes in the carotenoid biosynthesis pathway of Phaffia rhodozyma, represented in the sequence listing It will be clear to those having ordinary skill in the art, that once these DNA sequences have been made available it will be possible to bring about slight modifications to the DNA sequence without modifying the ammo acid sequence Such modifications are possible due to the degeneracy of the genetic code Such modifications are encompassed in the present invention However, also

modifications in the coding sequences are envisaged that create modifications m the amino acid sequence of the enzyme It is well known to those of skill m the art that minor modifications are perfectly permissible in terms of enzymatic acitivty Most changes, such as delections, additions or amino acid substitutions do not affect enzymatic acitivity, at least not dramatically Such variants as comprise one or more ammo acid deletions, additions or substitutions can readily be tested using the complementation test disclosed in the specification The skilled person is also familiar with the term "conservative ammo acid substitutions", meaning substitutions of amino acids by similar amino acids residing in the same group The skilled person is also familiar with the term "allelic variant", meaning naturally occurring variants of one particular enzyme These conservative substitutions and allelic enzyme variants do not depart from the invention

As stated, at the DNA level considerable variation is acceptable Although the invention discloses four DNA sequences, as represented in SEQIDNO 12, SEQIDNO 14, SEQIDNO 16, SEQIDNO 18, SEQIDNO 20, or SEQIDNO 22, in detail also isocoding variants of the DNA sequence represented in SEQIDNO 12, SEQIDNO 14, SEQIDNO 16, SEQIDNO 18, SEQIDNO 20, or SEQIDNO 22, are encompassed by the present invention Those of skill in the art would have no difficulty in adapting the nucleic acid sequence in order to optimize codon usage in a host other than P rhodozyma Those of skill in the art would know how to isolate allelic variants of a DNA sequence as represented in SEQIDNO 12, SEQIDNO 14, SEQIDNO 16, SEQIDNO 18, SEQIDNO 20, or SEQIDNO 22 from related Phaffia strains Such allelic variants clearly do not deviate from the present invention

Furthermore, using the DNA sequences disclosed in the sequence listing, notably SEQIDNO 12, SEQIDNO 14, SEQIDNO 16 or SEQIDNO 18, as a probe, it will be possible to isolate corresponding genes form other strains, or other microbial species, or even more remote eukaryotic species if desired, provided that there is enough sequence homology, to detect the same using hybridisation or amplification techniques known in the art

Typically, procedures to obtain similar DNA fragments involve the screening of bacteria or bacteπophage plaques transformed with recombinant plasmids containing DNA fragments from an organism known or expected to produce enzymes according to the invention After in situ replication of the DNA, the DNA is released from the cells or plaques, and immobilised onto filters (generally nitro¬ cellulose) The filters may then be screened for complementary DNA fragments using a labeled nucleic acid probe based on any of the sequences represented in the sequence listing Dependent on whether or not the organism to be screened for is distantly or closely related, the hybridisation and washing conditions should be adapted in order to pick up true positives and reduce the amount of false positives A typical procedure for the hybridisation of filter-immobilised DNA is described in Chapter 5, Table 3, pp 120 and 121 in Nucleic acid hybridisation- a practical approach, B D Hames & S J Higgms Eds , 1985, IRL Press, Oxford) Although the optimal conditions are usually determined empirically, a few useful rules of thumb can be given for closely and less closely related sequences

In order to identify DNA fragments very closely related to the probe, the hybridisation is performed as described in Table 3 of Hames & Higgins, supra, (the essentials of which are reproduced

below) with a final washing step at high stringency in 0 1 * SET buffer (20 times SET = 3M NaCl, 20 M EDTA, 0 4 M Tπs-HCl, pH 7 8), 0 1 % SDS at 68° Celsius)

To identify sequences with limited homology to the probe the procedure to be followed is as in Table 3 of Hames & Higgms, supra, but with reduced temperature of hybridisation and washing A final wash at 2 * SET buffer, 50°C for example should allow the identification of sequences having about 75% homology As is well known to the person having ordinary skill in the art, the exact relationship between homology and hybridisation conditions depend on the length of the probe, the base composition (% of G + C) and the distribution of the mismatches, a random distribution has a stronger decreasing effect on T _m then a non-random or clustered pattern of mismatches The essentials of the procedure described in Table 3, Chapter 5 of Hames & Higgins are as follows

( 1 ) prehybπdisation of the filters in the absence of probe, (2) hybridisation at a temperature between 50 and 68°C in between 0 1 and 4 * SET buffer (depending on the stringency), 10 * Denhardt's solution ( 100 * Denhardt's solution contains 2% bovine serum albumin, 2% Ficoll, 2% pol vinylpyrrolidone), 0 1% SDS, 0 1% sodiumpyrophosphate, 50 μg/ml salmon sperm DNA (from a stock obtainable by dissolving 1 mg/ml of salmon sperm DNA, sonicated to a length of 200 to 500 bp, allowed to stand in a water bath for 20 min , and diluted with water to a final concentration of 1 mg ml), hybridisation time is not too critical and may be anywhere between 1 and 24 hours, preferably about 16 hours (o/n), the probe is typically labeled by nick-translation using ³ P as radioactive label to a specific activity of between 5 * 10 ⁷ and 5 * 10 ⁸ c p m /μg, (3) (repeated) washing of the filter with 3 * SET, 0 1% SDS, 0 1% sodiumpyrophosphate at 68°C at a temperature between 50°C and 68°C (dependent on the stringency desired), repeated washing while lowering the SET concentration to 0 1% , wash once for 20 mm in 4 * SET at room temperature, drying filters on 3MM paper, exposure of filters to X-ray film in a cassette at -70°C for between 1 hour and 96 hours, and developing the film Generally, volumina of prehybπdisation and hybridisation mixes should be kept at a minimum All "wet" steps may be carried out in little sealed bags in a pre-heated water bath

The above procedure serves to define the DNA fragments said to hybridise according to the invention Obviously, numerous modifications may be made to the procedure to identify and isolate

DNA fragments according to the invention It is to be understood, that the DNA fragments so obtained fall under the terms of the claims whenever they can be detected following the above procedure, irrespective of whether they have actually been identified and/or isolated using this procedure

Numerous protocols, which can suitably be used to identify and isolate DNA fragments according to the invention, have been described in the literature and in handbooks, including the quoted Hames & Higgins, supra) With the advent of new DNA amplification techniques, such as direct or inverted PCR, it is also possible to clone DNA fragments in vitro once sequences of the coding region are known

Also encompassed by the claims is a DNA sequence capable, when bound to nitrocellulose filter and after incubation under hybridising conditions and subsequent washing, of specifically hybridising to a radio-labelled DNA fragment having the sequence represented in SEQIDNO 12,

SEQIDNO 14, SEQIDNO 16 or SEQIDNO 18, as detectable by autoradiography of the filter after incubation and washing, wherein said incubation under hybridising conditions and subsequent washing is performed by incubating the filter-bound DNA at a temperature of at least 50°C, preferably at least 55°C, more preferably at least 60°C in the presence of a solution of the said radio-labeled DNA in 0 3 M NaCI, 40 M Tπs-HCl, 2 mM EDTA, 0 1% SDS, pH 7 8 for at least one hour, whereafter the filter is washed at least twice for about 20 minutes in 0 3 M NaCI, 40 mM Tπs-HCI, 2 mM EDTA, 0 1% SDS, pH 7 8, at a temperature of 50°C, preferably at least 55°C, more preferably at least 60°C, prior to autoradiography

The heterologous DNA sequence according to the invention may comprise any open reading frame coding for valuable proteins or their precursors, like pharmaceutical proteins such as human serum albumin, IL-3, insulin, factor VIII, tPA, EPO, α-interferon, and the like, detergent enzymes, such as proteases and lipases and the like, cell wall degrading enzymes, such as xylanases, pectinases, cellulases, glucanases, polygalacturonases, and the like, and other enzymes which may be useful as additives for food or feed (e g chymosin, phytases, phospholipases, and the like) Such genes may be expressed for the purpose of recovering the protein in question prior to subsequent use, but sometimes this may not be necessary as the protein may be added to a product or process in an unpuπfied form, for example as a culture filtrate or encapsulated inside the Phaffia cells

The yeast cells containing the carotenoids can be used as such or in dried form as additives to animal feed Furthermore, the yeasts can be mixed with other compounds such as proteins, carbohydrates or oils

Valuable substances, such as proteins or pigments produced by virtue of the recombinant DNA of the invention may be extracted Carotenoids can also be isolated for example as described by Johnson et al (Appl Environm Microbiol 35 1 155-1 159 (1978))

Purified carotenoids can be used as colorants in food and/or feed It is also possible to apply the carotenoids in cosmetics or in pharmaceutical compositions

The heterologous downstream sequence may also comprise an open reading frame coding for reduced sensitivity against a selective agent The open reading frame coding for an enzyme giving G418 resistance was used satisfactorily in the method according to the invention, but the invention is not limited to this selection marker. Other useful selection markers, such as the phleomycin resistance gene may be used, as disclosed in EP 590 707 Each of these genes is advantageously expressed under the control of a strong promoter according to the invention, such as the GAPDH-promoter

Example 1 G-418 resistance of Phaffia transformant G418-1 To determine the expression of the G418 resistance gene in pGB-Ph9, transformant G418- 1 (EP 0 590 707 A l ) was exposed to increasing concentrations of G418

Two dilutions of a G418- 1 culture were plated onto YepD agar containing 0-1000 μg/ml G418 (Table 1 )

Table 1 Survival of Phaffia transformant G418-1 on YepD agar medium containing increasing concentrations of G418

At a concentration of 600 μg/ml G418 less than 1% of the plated cells survived It can be concluded, that despite multicopy integration of pGB-Ph9, G418-1 shows a rather weak resistance to G418 (Scorer et al , 1994, Bio/Technology 12, p 181 et seq , Jimenez and Davies, 1980, Nature 182 p 869 et seq ), most probably due to a weak action of the Phaffia actm promoter in the plasmid The results that the Phaffia actin promoter works poorly, prompted us to isolate promoter sequences of Phaffia with strong promoter activity

Example 2 Synthesis of specific probes of glycolytic genes from Phaffia rhodozyma by PCR

The polymerase chain reaction (PCR) technique was used in an attempt to synthesize a homologous probe of the genes encoding glyceraldehyde-3-phosphate dehydrogenase (GAPDH), s phosphoglycerate kmase (PGK) and the tπose phosphate isomerase (TPI) of Phaffia rhodozyma

A set of degenerated ohgonucleotides was designed based on the conserved regions in the GAPDH-gene (Michels et al , 1986 EMBO J 5 1049-1056), PGK-gene (Osinga et al , 1985 EMBO J 4 381 1-3817) and the TPI-gene (Swinkels ef α/ , 1986 EMBO J 5 1291-1298)

All possible oligo combinations were used to synthesize a PCR-fragment with chromosomal o DNA of Phaffia rhodozyma (strain CBS6938) as template Chromosomal DNA of Saccharomyces cerevistae and Kluweromyces lactis as template was used to monitor the specificity of the amplification The PCR was performed as described above, the PCR conditions were 1 ' 95 °C, 2' annealing temperature (T.), in 5' from annealing temperature to 72 °C, 2' 72 °C, for 5 cycli followed by 1 ' 95 °C, 2' 55 °C and 2' 72 °C for 25 cycli and another elongation step for 10' 72 °C Three different T _a were s used 40 °C, 45 °C and 50 °C

Under these conditions, only one primer combination produced a fragment of the expected size on chromosomal DNA of Phaffia as template Using the oligo combination no 3005 and 3006 and a T. of 45 °C a 0 3-kb fragment was found Specifically, the GAPDH ohgonucleotides correspond with am o acids 241-246 and 331-338 of the published S cerevistae sequence (It was concluded that to isolate the ;o promoters corresponding to the PGK- and TPl-genes from Phaffia, either further optimization of the PCR-conditions is required, or homologous primers should be used Another alternative method for isolating high level promoters is disclosed in the detailed description, supra

The amplified fragment was purified from the PCR reaction and was digested with BamxW and ligated into the dephosphorylated BamHl site of ρTZ19R The ligation mixture was transformed to 25 competent E coli DH5α cells prepared by the CaCl ₂ -method and the cell were plated on LB-plates with 50 μg/ml Amp and 0 1 mM IPTG/50 μg/ml X-gal Plasmid DNA was isolated from the white colonies The pTZ19R clone with the right insert, called pPRGDH I , was subsequently used for sequence analysis of the insert

The cloned sequence encoded for the carboxy terminal fragment of GAPDH of Phaffia as shown by 30 comparison with the GAPDH-gene sequence of S cerevisiae (Holland and Holland, 1979 J of Biol Chem 254 9839-9845)

Example 3 Isolation of the GAPDH-gene of Phaffia To obtain the complete GAPDH-gene including expression signals the 0 3-kb Bam HI fragment 35 of pPRGDHI was used to screen a cosmid library of Phaffia

Preparation of the vector for cosmid cloning

Vector preparation was simplified, because of the presence of a double cos-site in pMT6 PMT6 was digested to completion with blunt end cutter Pvuil to release the cos-sites Digestion efficiency was checked by transformation to £ coli DH5α and found to be >99%

The Pvull digested pMT6 was purified by phenol chloroform extraction and ethanol precipitation and finally solved in 30 μl TE at a concentration of 2 μg/μl

The vector was subsequently digested with cloning enzyme BamW\ and the vector arms were purified as described above ("Experimental")

Preparation of target DNA

Isolation of genomic DNA of Phaffia strain CBS6938 was performed as described in the part named "Experimental" The cosmid pMT6 containing inserts of 25-38-kb are most efficiently packaged Therefore genomic DNA was subjected to partial digestion with the restriction enzyme Sau3A Target DNA was incubated with different amounts of enzyme Immediately after digestion the reactions were stopped by the extraction of DNA from the restriction mixture with phenol-chloroform The DNA was precipitated by using the ethanol method and the pelleted DNA after centrifugation was dissolved in a small volume of TE Contour clamped homogeneous electric field (CHEF) electrophoresis was used to estimate the concentration and size of the fragments (Dawkins, 1989, J of Chromatography 492, pp 615-639)

Construction of genomic cosmid library

Ligation of approximately 0 5 μg of vector arm DNA and 0 5 μg of target DNA was performed in a total volume of 10 μl in the presence of 5 mM ATP (to prevent blunt end ligation) Packaging in phage heads and transfection to £ colt LE 392 as described in Experimental The primary library consisted of 7582 transfectants with an average insert of 28-kb as determined by restriction analysis The library represents 3 5 times the genome with a probability of the presence of all genes in the library of 0 97 as calculated according to Sambrook (supra) For library amplification the transfectants were pooled by resuspending in 8 ml LB-broth Additional 4 8 ml glycerol was added The transfectants mixture was divided into 16 samples of 800 μl each and stored at -80 °C This amplified library consisted of 2 9* 10 ⁹ transfectants

Screening of the cosmid library

A 100 μl sample was taken from this library and further diluted (10 ⁶ ) in LB-broth and 200 μl was plated onto 10 LB-plates containing ampiciliin The plates were incubated overnight at 37 °C Each plate contained 300-400 colonies and filters were prepared These filters were screened with the GAPDH-probe using hybridization and washing conditions as described above ("Experimental") After 16 hours exposure, 3 strong hybridization signals were found on the autoradiogram Cosmid DNA isolated from these positive colonies was called pPRGDHcosI, pPRGDHcos2 and pPRGDHcos3

Chromosomal DNA isolated from Phaffia rhodozyma strain CBS 6938 and cosmid pPRGDHcosI was digested with several restriction enzymes. The DNA fragments were separated, blotted and hybridized as described before. The autoradiograph was exposed for different time periods at

-80°C The film showed DNA fragments of different length digested by different restriction enzymes which hybridize with the GAPDH-probe (Fig. 1).

Furthermore, from Southern analysis of the genomic DNA of Phaffia using the GAPDH fragment as probe, it was concluded that the GAPDH-encodtng gene is present as a single copy gene in Phaffia rhodozyma, whereas in Saccaro yces cerevistae GAPDH is encoded by three closely related but unlinked genes (Boucheπe et al., 1995. FEMS Microb Letters 135: 127-134) Hybridizing fragments of pPRGDHcosI for which a fragment of the same length in the chromosomal DNA digested with the same enzyme was found, were isolated from an agarose gel. The fragments were ligated into the corresponding sites in pUC 19. The ligation mixtures were transformed to competent £ colt cells. The plasmids with a 3.3-kb Sail insert and a 5.5-kb £coRI insert were called pPRGDH3 and pPRGDHό, respectively. The restriction map of pPRGDH3 and pPRGDHό is shown in Figure 2 Analysis of the sequence data of the insert in pPRGDH I showed us that there was a Hindl site at the C-terminal part of the GAPDH-gene. From this data it was suggested that the insert in pPRGDHό should contain the complete coding sequence of GAPDH including promoter and terminator sequences.

Example 4 Characterization of the GAPDH-gene

In order to carry out sequence analysis without the need to synthesize a number of specific sequence primers a number of deletion constructs of plasmids pPRGDH3 and pPRGDHό were made using convenient restriction sites in or near the putative coding region of GAPDH gene

The plasmids were digested and after incubation a sample of the restriction mixture was analyzed by gel electrophoresis to monitor complete digestion. After extraction with phenol-chloroform the DNA was precipitated by ethanol. After incubation at -20 °C for 30' the DNA is pelleted by centrifugation, dried and dissolved in a large volume (0.1 ng/μl) of TE. After ligation the mixtures were transformed to E. colt. Plasmid DNA isolated from these transformants was analyzed by restriction analysis to reveal the right constructs In this way the deletion constructs pPRGDH3δHIII, pPRGDH6δ_3αwHI, pPRGDH6δSs/I and pPRGDHόδSα/I (Fig 1 )

In addition to this, the 0.6-kb and 0.8-kb Sst\ fragments derived from pPRGDHό were subcloned in the corresponding site of pUC19

Sequence analysis was carried out using pUC/M13 forward and reverse primers (Promega). The sequencing stategy is shown in fig. 2 (see arrows). On the basis of homology with the GAPDH-gene sequence of S cerevistae (Holland and

Holland, 1979 J of Biol Chem 254: 9839-9845) and K lactts (Shuster, 1990 Nucl. Acids Res. J_8, 4271 ) and the known splice site concensus J L. Woolford 1989 Yeast 5/ 439-457), the introns and the possible ATG start were postulated

The GAPDH gene has 6 introns (Fig 1 ) and encodes a polypeptide of 339 ammo acids This was completely unexpected considering the genomic organisation of the GAPDH genes of K lactis and __ cerevistae which have no introns and both consist of 332 am o acids The homology on the am o acid level between the GAPDH gene of Phaffia and K lactis and S cerevisiae is 63% and 61%, respectively

Most of the introns in the GAPDH gene are situated at the 5' part of the gene Except intron III all introns contain a conserved branch-site sequence 5'-CTPuAPy-3' found for S cerevistae and S pombe

By computer analysis of the upstream sequence using PC-gene 2 putative eukaryotic promoter elements, TATA-box (position 249-263 in SEQIDNO 1 1) and a number of putative Cap signal (between position 287 and 302 in SEQIDNO 1 1) were identified

Example 5 Cloning of the GAPDH promoter fused to G418 in pUCG418

In order to construct a transcription fusion between the GAPDH promoter and the gene encoding G418 resistence the fusion PCR technique was used

Using plasmid pPRGDHό the GAPDH promoter could be amplified by standard PCR protocols ("Experimental")

In the PCR mix pPRGDHό and oligo's No 5177 and 5126 (Sequences in "Experimental") were used A 416 bp DNA fragment was generated containing the entire GAPDH promoter sequence In addition this fragment also contains a Hindϊll, Xho\ and a Kpnl restriction site at it's 5'end and 12 nt overlap with the 5' end of the gene encoding G418 resistance

The 217 bp portion of the 5'end of the G418 coding sequence was also amplified by PCR using pUC-G418 and oligo's 4206 and 5127 A 226 bp DNA fragment was obtained containing the 217 bp 5'end of G418 and having a 9 nucleotides overlap with the 3'end of the earlier generated GAPDH promoter fragment It also contained a Mscl site at it's 3end

The PCR fragments were purified from the PCR mixture using the WIZARD Kit Approximately 1 μg of the GAPDH promoter fragment and 1 μg of the G418 PCR fragment were useϊl together with oligo's 5177 and 4206 in a fusion PCR experiment (Experimental) A 621 bp DNA fragment was generated, containing the GAPDH promoter directly fused to the 5' portion of G418 After purification the DNA fragment was digested with Mscl and Kpnl The 3 4 Kb Mscl-Kpnl fragment of pUC-G418, containing pUC sequences and the 3' portion of G418, was used as a vector The ligation mixture was transformed to competent £ colt DH5α cells Transformant colonies containing the fusion PCR DNA inserted were identified by digestion with different restriction enzymes

Thus, plasmid pPRl was obtained, containing the GAPDH promoter directly fused to the G418 marker gene Three pPRl vectors isolated from independent transformants were used in further cloning experiments

To target the plasmid, after transformation, to a specific integration site a 3 0-kb SstI fragment containing a part of the ribosomal DNA of Phaffia was cloned in pPRl The ribosomal DNA fragment was isolated from an agarose gel after digestion with Sst of plasmid pGB-Phl l (EP 590 707 A l) This

fragment was ligated in the dephosphorylated SstI site of pPRl The ligation mixture was transformed to competent £ coli cells Plasmid DNA was isolated and using restriction analysis it was shown that several colonies contain the expected plasmid pPR2 The complete cloning strategy is shown in Fig 3

Example 6 Transformation of Phaffia with pPR2 Transformation of Phaffia strain 6938 was performed using an eiectroporation procedure as previously described by Faber et al (1994, Curr Genet 1994 25,305-310) with the following modifications

- Electropulsing was performed using the Bio-rad Gene Pulser with Pulse Controller and with Bio-rad 2mm cuvettes

- Phaffia was cultivated for 16 h at 21 °C

- Per transformation 2xl0 ⁸ cells were used together with 5 μg of linearized vector Linearization was done in the rDNA sequence using Clal to enable integration at the rDNA locus in the Phaffia genome Following the electric pulse (7 5kV/cm, 400 Ω and 25 μF) 0 5 ml YePD medium was added to the cell/DNA mixture The mixture was incubated for 2 5 h at 21 °C and subsequently spread on 5 selective YEDP agar plates containing 40 μg/ml G418

As shown in Table 2 we were able to generate transformants with 1 15 transformants per μg DNA, the average transformation frequency was 50 transform ants/μg pPR2 as judged over a number of experiments Transformation of the closed circular form of pPR2 did not result in transformation suggesting that there is no autonomously replicating sequence present within the vector sequences Using pPR2 a 10 to 50-fold increase in transformation frequency was found compared to a previous constructed transformation vector for Phaffia, called pGB-Ph9 In this latter vector a translation fusion was made between the 5' part of the actm gene of Phaffia and G418

In order to analyze the level of resistance of transformants the mixture or DNA/cells was plated onto selective plates containing different amounts of G418 Although the total number of transformants decreases with the increasing amounts of G418, we were still able to obtain a considerable number of transformants (table 3)

In another experiment 30 transformants obtained under standard selection conditions (40 μg/ml) were transfered to plates containing 50, 200 or 1000 μg/ml After incubation of the plates at 21 °C for 4-5 days, 23 transformants out of 30 tested were able to grow on plates containing 200 μg/ml G418 One transformant was able to grow on plates containing upto and above 1000 μg/ml G418

Table 3. Comparison of G418 sensitivity as a result of two different G418-resistance genes in

To analyse the integration event and the number of integrated vector copies total genomic DNA from six independent transformants was isolated. Therefore these transformants were cultivated under selective conditions, i.e. YePD + 50 μg/ml G418. Chromosomal DNA was digested with Clal. The DNA fragments were separated by gel electrophoresis and transfered to nitrocellulose and the Southern blot was probed with Phaffia DNA.

Besides the rDNA band of 9.1 kb an additional band of 7.1 kb of similar fluorescing intensity was observed in the transformants. This band corresponds to the linearised form of pPR2. From the intensity of these bands it was concluded that the copy number was about 100 - 140 copies of pPR2. These results are similar to those observed for pGB-Ph9, ruling out that the improved G418-resistance is due to differences in copy number of integrated vectors alone. It is not known whether the multiple copy event is caused by multiple copy integration of pPR2 or by the amplification of a single copy in the rDNA or a combination of both events.

Example 7

Construction of pPR2T bv cloning the GAPDH-terminator into pPR2

Eukaryotic mRNAs contain modified terminal sequences, specificaly the 3' terminal poly(A). As the prokaryotic gene encoding G418 resistance lacks eukaryotic termination signals, which might effect proper transcription termination and mRNA stability (1994, Raue, H.A., TIBTECH XT. 444-449), a part of the 3' non-coding sequence of GAPDH was introduced.

To that end, a 307 bp fragment, consisting of 281 bp of the 3' non-coding region of GAPDH and other additional cloning sequences, was amplified by PCR using the oligo's 5137 and 5138 ("Experimental"). The upstream oligo 5137 consists of the last 14 nucleotides of the coding and 17 nucleotides of the 3' non-coding region of GAPDH. By base substitutions of the 5th (T --> A) and 8th (T --> C) nucleotide

of the non-coding sequence a BamHl restriction site was introduced In addition this fragment contains a Xhol and a Hindlll restriction site at its 3' end

The PCR fragment was purified from the PCR mixture using the WIZARD Purification Kit and digested with BamHl and Hindlll A 288 bp fragment was isolated and cloned into the corresponding sites of the previously constructed Phaffia transformation vector pPR2, yielding pPR2T

Upon transformation of Phaffia, using G418 as selective agent, the transformation frequencies (number of transformants per μg of DNA) obtained with the improved construct pPR2T was approximately 5 to 10 times higher than the transformation frequency of pPR2 (/ e without a Phaffia homologous transcription termination signal) The results of a typical experiment are given in Table 4

Table 4 Transformation frequency at 50 ttg/ml G418 for pGB-Ph9, pPR2 and pPR2T

Vector transformants transformants/μg DNA pGB-Ph9 (ccc) pGB-Ph9 (x_3g/II) 60 1 pPR2 (ccc) 1 pPR2 (xCIal) 3000 - 9600 50 - 160 pPR2T (ccc) pPR2T (xCtαl) 45600 760 pPR2T (xSftl) 1080 18

Phaffia cells transformed with pPR2T were tested for their ability to grow on high levels of G418 The level of G418 on which growth is still possible was taken as a measure of the expression level of the G418 resistance gene in transformants, as a result of the presence of the Phaffia promoter, and/or terminator Preliminary results indicate that the number of transformants able to grow on high levels of G418 are significantly higher than without terminator

In summary

From the above results, it was concluded, that the presence of the GAPDH-promoter (pPR2) resulted in a considerable increase of the transformation frequency (from 1 to at least 50 per μg of DNA) when compared to the vector containing the actin-promoter (pGB-Ph9) These results are in line with the results obtained with the G418 sensitivity test (Table 3 and 4) which indicate superior expression levels under the control of the GAPDH promoter The possibility that the difference in transformation frequency could be due solely to the difference in linearising the vectors, (Bglll, Clal and Sfi all cut inside the ribosomal DNA locus, but at different positions), was ruled out by comparison of pPR2(x_S//I) with pGB-Ph9(x_S/.I) The difference in transformation frequency between the two pPR2 and pGB-Ph9, linearised with Sfil is still considerable However, it is concluded that the choice of the linearisation site does have effect on the transformation frequency, linearisation with Clal is preferred

The improvements obtained by using a high-level promoter, such as GAPDH, are irrespective of whether a homologous terminator is used (pPR2 (without homologous terminator) performs far better than pGB-Ph9, both in G418 sensitivity tests, as well as in terms of transformation frequency)

The presence of a homologous terminator results in both higher transformation frequencies and higher expression levels, this result is concluded to be independent of the promoter used Preliminary results indicate that considerable improvements are obtained when the pGB-Ph9 construct is completed with a transcription terminator, such as the GAPDH-terminator used in pPR2T

The following Examples illustrate the isolation of DNA encoding enzymes involved in the carotenoid biosynthesis pathway of Phaffia rhodozyma These DNA sequences can suitably be used for a variety of purposes, for example to detect and isolate DNA sequences encoding similar enzymes in other organisms, such as yeast by routine hybridisation procedures, to isolate the transcription promoters and/or terminators, which can be used to construct expression vectors for both heterologous as well as homologous downstream sequences to be expressed The DNA sequences encoding carotenoid s biosynthesis genes can suitably be used to study the over-expression, either under the control of their own promoters or heterologous promoters, such as the glycolytic pathway promoters illustrated above For example, transformation of Phaffia rhodozyma with carotenoid encoding DNA sequences according to the invention effectively results in amplification of the gene with respect to the wild-type situation, and as a consequence thereof to overexpression of the encoded enzyme o Hence, the effect of over-expression of one or more genes encoding carotenoid biuosynthesis genes can thus be studied It is envisaged that mutant Phaffia strains can be obtained producing higher amounts of valuable carotenoids, such as β-carotene, cantaxanthin, zeaxanthin and/or astaxanthin Similarly, the DNA sequences encoding enzymes involved in the carotenoid biosynthesis pathway can be introduced into other hosts such as bacteria, for example £ coli yeasts, for example species of Saccharomyces, 5 Kluyveromyces, Rhodosporidium, Candida, Yarrowia, Phvcomyces, Hansenula Picchta, fungi, such as Aspergillus, Fusanum, and plants such as carrot, tomato, and the like The procedures of transformation and expression requirements are well known to persons skilled in these arts

Heterologous expression of carotenogen c gene from Erwinia uredovora in Phaffia rhodozyma

The coding sequence encoding phytoene synthase (crtB) of Erwinia uredovora (Misawa et al , 1990) was cloned between the promoter and terminator sequences of the gpd (GAPDH-gene) of Phaffia by fusion PCR In two separate PCR reactions the promoter sequence of gpd and the coding sequence of o crtB were amplified The former sequence was amplified using the primers 5177 and 5128 and pPR8 as template This latter vector is a derivative of the Phaffia transformation vector pPR2 in which the promoter sequence has been enlarged and the Bgll restriction site has been removed The promoter sequence of gpd was amplified by PCR using the primers 5226 and 5307 and plasmid pPRgpdό as template The amplified promoter fragment was isolated, digested with Kpnl and BamHl and cloned in ^• >s the Kpnl-Bglll fragment of vector ρPR2, yielding pPR8 The coding sequence of crtB was amplified using the primers 5131 and 5134 and pACCRT-EIB as template In a second fusion PCR reaction, using the primers 5177 and 5134, 1 μg of the amplified promoter and crtB coding region fragment used as template yielding the fusion product Pgpd-crtB The terminator sequence was amplified under standard PCR conditions using the primers 5137 and 5138 and the plasmid pPRgdhό as template Primer 5137 o contains at the 5' end the last 1 1 nucleotides of the coding region of the crtB gene of £ uredovora and the first 16 nucleotides of the terminator sequence of gpd gene of P rhodozyma By a two basepair substitution a _3 mHI restriction site was introduced The amplified fusion product (Pgpd-crtB) and the amplified terminator fragments were purified and digested with Hindlll and BamHl and cloned in the dephosphorylated Hmdlll site of the cloning vector pMTL25 The vector with the construct Pgpd-crtB- 35 gpd was named pPREX 1 1

The Hmdlll fragment containing 'he expression cassette Pgpd-crtB -Tgpd was isolated from pPREX I 1 and ligated in the dephosphorylated Hmdlll site of the Phaffia transformation vector pPR8 After transformation of the ligation mixture into £ coli a vector (pPR8cr/B6 1 ) with the correct insert was chosen for Phaffia transformation experiments

Example 17 Isolation and characterization of the crtB gene of Phaffia

It will also be possible to express the Phaffia rhodozyma gene corresponding to crtB and express it under the control of its own regulatory regions, or under the control of a promoter of a highly expressed gene according ot the invention The Phaffia transformation procedure disclosed herein, invariably leads to stably integrated high copy numbers of the introduced DNA, and it is expected, that expression of the gene under the control of its own promoter wtll also lead to enhanced production of

carotenoids, including astaxanthin. To illustrate the principle, a protocol is given for the cloning of the crtB genomic sequence, below.

To obtain the genomic cr._3-gene including expression signals the 2.5 kb BamHl-Xhol fragment was isolated from the vector pPRcrtB and used as probe to screen a cosmid library of Phaffia. The construction and screening of the library was carried out as described in Example 3 using the crtB gene as probe instead of the gapdh-gene.

After the rounds of hybridization, 2 colonies were identified giving a strong hybridization signal on the autoradiogram after exposure. Cosmid DNA isolated from these colonies was called pPRgcrtB#l . l and pPRgcrtB#7, respectively.

Chromosomal DNA isolated from Phaffia rhodozyma strain CBS 6938 and cosmid pPRgcrtB#7 was digested with several restriction enzymes. The DNA fragments were separated, blotted and hybridized with a amino-terminal specific probe (0.45 kb Xbal fragment) of crtB under conditions as described before. After exposure, the autoradiogram showed DNA fragments of different length digested by different restriction enzymes which hybridized with the crtB probe. On the basis that no £coRI site is present in the cDNA clone a £coRI fragment of about 4.5 kb was chosen for subcloning experiments in order to determine the sequence in the promoter region and to establish the presence of intron sequences in the crtB gene. A similar sized hybridizing fragment was also found in the chromosomal DNA digested with £coRI. The fragment was isolated from an agarose gel and ligated into the corresponding site of pUC 19. The ligation mixture was transformed to competent £. coli cells. Plasmids with the correct insert in both orientations, named pPRIO. l and pPR10.2, were isolated from the transformants. Comparison of the restriction patterns of pPR10.1/pPR10.2 and pPRcrtB digested with Xbal gave an indication for the presence of one or more introns as the internal 2.0 kb Xbal fragment in the cDNA clone was found to be larger in the former vectors. The subclone pPRIO. l was used for sequence analysis of the promoter region and the structural gene by the so-called primer walking approach. The partial sequence of the insert in show in SEQIDNO: 22. Comparison of the cDNA and the genomic sequence revealed the presence of 4 introns.

Example 18 Isolation of promoter sequences with high expression levels

This example illustrates the the feasibility of the "cDNA sequencing method" referred to in the detailed description, in order to obtain transcription promoters from highly expressed genes.

For the isolation and identification of transcription promoter sequences from Phaffia rhodozyma genes exhibiting high expression levels, the cDNA library of Phaffia rhodozyma was analyzed by the following procedure.

The cDNA library was plated on solified LB-medium containing Amp and 96 colonies were randomly picked for plasmid isolation. The purified plasmid was digested with Xhό and Xbal and loaded on a agarose gel. The size of the cDNA inserts varied from 0.5 to 3.0 kb. Subsequently, these plasmids were used as template for a single sequence reaction using the T3 primer. For 17 cDN A clones no sequence data were obtained. The sequences obtained were translated in all three reading frames. For

each cDNA sequence the longest deduced amino acid sequences were compared with the SwissProt protein database at EBI using the Blitz program For 18 deduced ammo acid sequences no homology to known proteins was found whereas six ammo acid sequences showed significant homology to hypothetical proteins Fifty-five amino acid sequences were found to have significant homology to proteins for which the function is known About 50 % (38/79) were found to encode ribosomal proteins of which 12 full-length sequences were obtained

Table 13 Overview of expressed cDNAs, encoded proteins and reference to the Sequence Listing

By sequence homology it was concluded that in Phaffia the 40S πbisomal protein S37 is fused to ubiquitin as is found in other organisms as well The nucleotide sequences and deduced amino acid sequences of the full length cDNA clones are listed in the sequence listing Six ribosomal proteins were represented in the random pool by more than one individual cDNA clone The 40S ribosomal proteins S10 (SEQIDNO 44), S37 (+ ubiquitin) (SEQIDNO 24) and S27 (SEQIDNO 28) were represented twice and 60S (acidic) ribosomal proteins P2 (SEQIDNO 38), L37 (SEQIDNO 46) and L25 (SEQIDNO 36) found three times From these results we conclude, that these proteins are encoded by multiple genes or that these genes are highly expressed Therefore isolation of these promoter sequences are new and promissing target sequences to isolate high level expression signals from Phaffia rhodozyma Furthermore, a cDNA clone was isolated which showed 50 % homology to an abundant glucose- repressible gene from Neurospora crassa (Curr genet 14 545-551 (1988)) The nucleotide sequence and the deduced amino acid sequence is shown in SEQIDNO 26 One of the advantages of such a promoter sequence is that it can be used to separated growth (biomass accumulation) and gene expression (product accumulation) in large scale Phaffia fermentation

For the isolation of the promoter sequences of interest (as outlined above) a fragment from the corresponding cDNA clone can be used as probe to screen the genomic library of Phaffia rhodozyma following the approach as described for the GAPDH-gene promoter (Example 3, supra) Based on the determined nucleotide sequence of the promoter, specific ohgonucleotides can be designed to construct a transcription fusion between the promoter and any gene of interest by the fusion PCR technique, following the procedure as outlined in Example 5 (supra)

Example 19

Isolation of carotenogenic genes bv heterologous hybridization o For the identification and isolation of corresponding carotenoid biosynthetic pathway genes from organisms related to Phaffia rhodozyma heterologous hybridization experiments were carried out under conditions of moderate stringency In these experiments chromosomal DNA from two carotenogenic fungi (Neurospora crassa and Blakeslea trispora) and the yeasts S cerevistae and three yeast and fungal species from the genus Cystofylobasidium was used These three carotenogenic yeasts are, based on

5 phylogenetic studies, the ones most related to P rhodozyma

Chromosomal DNA from the yeast species Cystofylobasidium infirmo-miniatum (CBS 323), C bisporidit (CBS 6346) and C capttatum (CBS 6358) was isolated according the method as developed for Phaffia rhodozyma, described in example 3 of European patent application 0 590 707 A l , the relevant portions of which herein incorporated by reference Isolation of chromosomal DNA from the fungi 2o Neurospora crassa and Blakeslea trispora was essentially carried as described by Kolar et al (Gene, 62 127-134), the relevant parts of which are herein incorporated by reference

Chromosomal DNA (5 μg) of C infirmo-miniatum, C bisporidu, C capitatum, S cerevistae, P rhodozyma, N crassa and B trispora was digested using £coRI The DNA fragments were separated on a 0.8% agarose gel, blotted and hybridized using the following conditions 25 Hybridization was carried out at two temperatures (50 °C and 55 °C) using four different ^3ϊ P labelled Phaffia probes The probes were made using random primed hexanucleotide labellings reactions using the Xhol-Xbal fragment(s) from the cDNA clones pPRcrtE, pPRcrtB, pPRcrtl and pPRidi as template Hybridization was carried out o/n (16 h) at the indicated temperatures After hybridization the filters were washed 2 times for 30 min at the hybridization temperatures using a solution of 3*SSC, 0 1 3o % SDS, 0.05% sodiumpyrophosphate Films were developed after exposure of the filters to X-ray films in a cassette at -80 °C for 20 h

Using the cDNA clone of crtE of P rhodozyma faint signals were obtained for C infirmo- mintatum, C capitatum Using the cDNA clone of crtB of P rhodozyma strong signals were obtained to the high molecular weight portion of DNA from C infirmo-miniatum and C capitatum Furthermore a 35 strong signal was obtained in the lane loaded with digested chromosomal DNA from B trispora Only a faint signal was obtained for C capitatum at 50 °C using the cDNA clone of crti of P rhodozyma Using the cDNA clone of idi of P rhodozyma faint signals were obtained with chromosomal DNA from C infirmo-miniatum, C bisporidu and C capitatum at both temperatures A strong signal was obtained in the lane loaded with digested chromosomal DNA from B trispora

We conclude, that carotenoid biosynthesis cDNAs or genes, or idi cDNAs or genes, can be isolated from other organisms, in particular from other yeast species by cross-hybridisation with the cDNA fragments coding for P rhodozyma carotenoid biosynthesis enzymes, or isopentenyl pyrophosphate isomerase coding sequences respectively, using moderately stringent hybridisation and washing conditions (50 °C to 55 °C, 3xSSC)
