Systems for expression of heterologous proteins in M. capsulatus.

The present invention relates to the expression of heterologous proteins in the bacteria M. capsulatus. More specifically, the present invention relates to the exportation and display of polypeptides and proteins on the surface of said bacteria.

Thus, the present application relates to a recombinant vector, a bacterial host cell transformed with said vector, a method for producing a desired protein in a bacterial host cell, a protein capable of being exposed on the surface of a methanotrophic bacterium, and a fusion protein.

The expression of polypeptides on the surface of bacteria and bacteriophages has been pursued for several years, in part because of interest in recombinant antibody production. Many other potential applications exist, including the production of genetically-engineered whole cell adsorbents, construction of "peptide libraries", cell bound enzymes, and use as live vaccines or immunogens to generate antibodies.

In bacteria, one approach to obtaining surface expressed foreign proteins has been the use of native membrane proteins as a carrier for a foreign protein. In general, most attempts to develop methods of anchoring proteins on a bacterial surface have focused on fusion of the desired recombinant polypeptide to a native protein that is normally exposed on the cell's exterior with the hope that the resulting hybrid will also be localized on the surface.

In a prior invention (Norwegian patent application no. 20033176) the present inventors also provided an expression system where a heterologous polypeptide (termed "desired" protein) was expressed in the bacteria Methylococcus capsulatus. The heterologous protein is preferably linked to an outer membrane protein in M. capsulatus termed MopE.

MopE has a 540 amino acid protein sequence, with a short (29 amino acids) N-terminal sequence dependent signal sequence, followed by a N-terminal domain (176 amino acids) and a C-terminal domain (335 amino acids). The N-terminal domain is not secreted, while the C-terminal domain is secreted and expressed on the cell surface. The MopE amino acid sequence is shown in the sequence listing, as Seq. ID. no. 1

The method of secretion is not known. MopE does not show high sequence similarity to other known secreted proteins. The secretion is host specific, although inserted in the

IM and released to the periplasm, the MopE protein is not secreted by E. coli hosts, only by M. capsulatus. MopE has been proposed to be secreted either by the Type 2 Secretion system (T2S) or the Type 5 Secretion system (T5S) based upon its primary sequence (Fjellbirkeland et al, 2001). Proteins secreted by the T2S or T5S systems can be translocated across the IM either by the Tat or the Sec machinery, which are shown in figure 1.

Secretion of T2S substrates is very host specific. Secretion by the T2S system (Fig. no. 1) is a two-step process in which the secreted protein initially is exported across the IM by the Sec or Tat export systems. The periplasmatic intermediate is subsequently translocated across the OM by the T2S secretion through the channel formed by the secretin that is large enough to translocate folded or close to folded substrates. T2S is energized by ATP, and although not required for secretion, the proton motive force increases the rate of secretion. Substrates of the T2S system share no obvious similarities in primary sequence. Although no recognition signal that confine proteins to secretion by the T2S pathway has been identified, a potential common feature for T2S substrates is a medium to high content of β-sheet (de Vries et al, 1990 and Sandkvist, 2001). β-strands were predicted in the N-terminal domain of MopE by the computer program PRED-TMBB (http://bioinfromatics.biol.uoa.gr/PRED-TMBB). and this program also predicted an N-terminal β-barrel in MopE. The predicted β-strands may form the tertiary structures of β-sheets required for translocation by the T2S pathway. In addition to the prediction of such structures in N-terminal domain of Mop-E, MopE ⁰ is heat-modifiable while MopE* is not (Fjellbirkeland et al, 2001), indicating that the N- terminal domain of MopE indeed contains stabile β-structures, and thus is a candidate T2S substrate. Since a Sec-compatible signal sequence has been predicted in MopE it has been considered likely that the Sec machinery export MopE across the IM.

However, the presence of β-structures does not confine secreted proteins to the T2S route. Substrates of T5S, autotransporters, require a β-domain that forms a β-barrel that allows for translocation of the passenger domain across the OM. Since the N-terminal domain of MopE has the potential of containing β-structures, the domain could function as an autotransporter translocation unit in T5S. No autoproteolytic activity could be demonstrated for MopE using the substrate azocasein, however, such activity is not a widely distributed feature among T5S substrates, and thus not required. And while autotransporters inherently contain all information and accessory factors necessary for translocation to the OM, release of the protein to the extracellular space most often require cleavage by an external protease. Thus secretion by T5S is somewhat dependent

on the host cell, and the host specificity observed for the secretion of MopE does not exclude secretion by the T5S route.

Thus, it was thought that the most likely mechanism for translocation of MopE was either by the T2S or T5S routes, by the Sec or Tat transport systems. This translocation would then require the β-structures found in the N-terminal domain of MopE. Thus it was expected that the removal of the N-terminal domain of MopE would abolish the ability of the truncated protein, here termed MopE ^H *, to translocate. The MopE ^H * amino acid sequence is shown in the sequence listing, as Seq. ID. no. 2

The inventors constructed a mutated MopE protein, MopE ^H *, that consisted of the secreted domain of MopE alone, and did not contain the N-terminal MopE domain. (Please see Fig. no. 2. for a comparison of MopE and MopE ^H *) Quite surprisingly, they found that MopE ^H * fully retained its' ability to translocate in M. capsulatus.

Experiments were also performed to acertain the usefulness of MopE ^H * as part of a fusion protein acpable of translocation, by expressing Atlantic halibut nodavirus capsid protein fused to the surface protein MopE. As shown below, these fusion proteins were indeed capable of translocation.

As stated, this translocation of MopE ^H *, with or without a fused protein, is very surprising because it was thought that the N-terminal of MopE was required for translocation by the T2S or T5S routes. In addition, even though a protein in its entirety, here MopE, is known to be translocated, there is no reason to believe that only parts of the protein also may be able to do so.

The importance of this invention is fairly self evident. If one is to use MopE as a translocation system, there is an advantage to narrow it down to the smallest possible protein. There are always limits to how large of a protein (i.e. how long of a amino acid chain) may be transported. By removing a part of the native protein (here the N-terminal domain) one may, as shown, fuse a proportionally larger protein to the truncated MopE protein, and still have a reasonable expectation of successful translocation. In addition, the discovery that the N-terminal is not involved in translocation, changes the understanding of how MopE is translocated, and points research in new directions in trying to ascertain the mechanisms behind the translocation.

The invention can be better understood with reference to the following figures:

Fig. no. 1. Overview of secretion by the Type 2 and Type 5 secretion systems. (A)

The T2S system secretion consists of 12-16 proteins depending of species. The majority of the T2S components are IM proteins, many with large periplasmatic domains. Two of these GspE and GspL interact with ATP and are involved in energizing of the secretion. In the OM 12-14 GspD and GspS units form a secretin. The secretin is a transmembrane complex with a channel 5-10 ran in diameter, thus large enough to translocate folded or close to folded polypeptides. (B) Proteins secreted by T5S are pre-pro-proteins consisting of three domains: an N-terminal signal sequence for export across the IM, an internal passenger/functional domain and a C-terminal β-domain. The figures (A) and (B) are reproduced from (Voulhoux et al, 2001) and ( Desvaux et al, 2004), respectively.

Thus, the recombinant vector according to the present invention comprise a first nucleotide sequence Seq. ID no. 4, or sequences homologous thereto, capable of translocation through the outer membrane of Methylococcus capsulatus.

Also, the bacterial host cell according to the present invention is transformed with said recombinant vector.

And, the method for producing a desired protein in a bacterial host cell according to the present invention comprise transforming a bacterial host cell with a recombinant vector comprising a first nucleotide sequence Seq. ID no. 4 or sequences homologous thereto, and said vector comprising a further nucleotide sequence encoding said protein, said further nucleotide sequence being operably linked in frame to said first nucleotide sequence, and culturing said transformed host cell in a suitable medium under conditions allowing expression of said protein.

And, the protein capable of being exposed on the surface of a methanotrophic bacterium according to the present invention is encoded for by Seq. ID no. 2 or sequences homologous thereto.

And, the fusion protein according to the present invention comprise a protein or peptide sequence encoded for by a nucleotide sequence Seq. ID no. 4 or sequences homologous thereto, and a desired protein or peptide, capable of being translocated.

The fusion protein according to the invention is preferably expressed from a chimeric DNA having a DNA segment encoding a leader amino acid sequence capable of mediating secretion of the fusion protein, a DNA segment encoding for subunits of the surface protein, and a DNA segment encoding the desired target protein. The DNA segments are positioned such that expression of the fusion protein results in display of the target protein on the surface of the cells. The fusion proteins are preferably anchored to the cell surface of the bacteria forming what is referred to as a "display bacteria."

The present invention thus provides for a system for the expression of heterologous proteins, where the heterologous proteins are expressed on the surface of the bacterial cells.

The chimeric DNA may be integrated into the bacterial cell chromosome or be carried by a vector, where said vector preferably dose not comprise the entire nucleotide sequense of MopE (Seq. ID no 3), but rather only the truncated sequence comprising

MopE ^H * (Seq. ID no 4). In certain preferred embodiments, expression of the fusion protein may be regulated by an inducible promoter. Bacteria displaying a particular protein may be selected, for example, using antibody affinity. The fusion protein can be detached from selected cells. If desired, the target protein may be separated from the surface protein and further purified.

Target proteins useful in the present invention include peptides, proteins, e.g., hormones, enzymes, inhibitors, and receptors, antigens, antibodies including antibody fragments and single-chain antibodies.

The present invention thus provides a system for the expression of heterologous proteins in the membrane fraction, and preferable on the cell surface of the M. capsulatus.

The bacterium M. capsulatus is able to utilise methane as a single carbon and energy source. Bacteria capable of oxidising methane are collectively referred to as methanotrophs. They belong to different families and groups of the eubacteria but have in common the possession of the unusual enzyme methane mono oxygenase, which catalyses the oxidation of methane to methanol.

The bacterium has an obligate requirement for methane or methanol and an optimum growth temperature of 45 °C. Methane is oxidized via methanol to formaldehyde which is either assimilated into cellular biomass or dissimilated to carbon dioxide to release cellular energy.

M. capsulatus has a gram-negative cell envelope. Much of the intracellular space is occupied by an extensive intracytoplasmic membrane system. The genome of M. capsulatus (Bath) has a molecular weight of 2.8 x K)" Da and a G + C content of 62.5 %.

Commercial interests involving M. capsulatus and other methanotrophs could roughly be divided into two categories: Those taking advantage of the inexpensive growth requirements of the bacteria and those taking advantage of unique catalytic activities possessed by the bacteria.

The development of high-cell density fermentation technology for M. capsulatus has created the possibility of producing large quantities of specialised compounds like for instance amino acids, cofactors, vitamins, metabolic end products, and various high value proteins, at reasonable costs.

The present invention thus provides a system for the manufacturing of such product.

Other uses for the protein display methods of the present invention include, for example, epitope mapping, screening of antibody libraries and live bacterial vaccines.

The invention is especially suited for production of vaccines that can be administered orally for use in animals, fish and humans. The technique can also potentially be used for display of vaccines, especially for oral administration.

The invention relates to the use of the genes and the proteins encoded by them, as given in the accompanying sequences list, fragments thereof, or functionally equivalent substantially similar genes, for construction of fusion proteins carrying foreign peptide sequences for display in the M. capsulatus, and preferable on the surface of said bacterium. The term "homology" or "homologous", as used in the present application, does not necessary infer a common evolutionary ancestor/relationship, as homologous sequences may be artificially created. Rather, it is meant to encompass sequences that are similar and have a similar function, that is, sequences likely to be able to perform the same/similar function due to having a degree of sequence similarity (that may be defined as a percentage sequence similarity/identity).

M. capsulatus is a bacterium licensed for use in animal and fish feed. It has no virulent or pathogenic properties, and contains very low amounts of endotoxin (LPS). It is thus well suited as a carrier organism for recombinant oral vaccines, with a potential also for use in humans. Vaccines could be constructed by insertion of fragments of Dl 5 genes from pathogens into the M. capsulatus D 15 gene in order to display a fusion-protein containing parts of the two Dl 5 antigens on the surface of M. capsulatus. The part of the Dl 5 protein originating from the pathogen should trigger an immune response to the respective pathogenic bacterium. If replacement of M. capsulatus -specific Dl 5 sequences with corresponding sequences from the pathogens is well tolerated by the host, larger regions of Dl 5 could be replaced, and if possible, the entire Dl 5 protein could be replaced by the corresponding protein from a pathogen.

Due to the sequence conservation of Dl 5 among distantly related bacteria, exchange of parts of the gene (or the entire gene) without seriously affecting the survival and growth of M. capsulatus is plausible. The specific function of the Dl 5 antigen on the surface of the bacteria is not known, but it possibly plays a structural role and is most probably not involved in any important biochemical processes.

Successful display of the target protein on the cell surface can be detected using a number of methods, for example, if the target peptide can be specifically labeled by a procedure that does not operate through the membrane, its cell surface display can be readily demonstrated.

If the target polypeptide displays enzymatic activity, one may use such activity to demonstrate cell surface display. Antibodies against the target protein may also be used.

The chimeric DNA may be integrated into the host cell chromosome or be carried within a vector. Methods of integrating DNA into a host cell chromosome are well known in the art. The chimeric DNA may also be carried within a recombinant vector, e.g., a plasmid.

Plasmids useful as the vector backbone include plasmids containing replicon and control sequences which are derived from species compatible with the host cell. The vector may also contain an inducible promoter and marker gene, e.g., antibiotic resistance.

Introduction of the chimeric DNA to the host cell may be effected by any method known to those skilled in the art. For example, if a recombinant vector carries the DNA, the vector can be introduced, for example, by transformation, electroporation, or phage transfection.

The detection techniques noted above can be used initially to verify that the method of the present invention is working, i.e., that the fusion surface protein has been expressed and transported to the bacterial cell surface and is orientated so that the target protein is accessible i.e., displayed.

Cells that display the target may be separated from those that do not, using, for example, affinity separation techniques. Such techniques include affinity column chromatography, batch elution from affinity matrix material and fluorescent-activated cell sorting.

MopE is a major outer membrane protein of M capsulatus. It contains surface-exposed regions but its exact folding and association with the cell surface is not known. Under copper limitations, the C-terminal part of the protein is secreted into the growth medium, but considerable amounts of the full-length protein remains associated with the cell surface. By using this protein as an anchor it is possible to mediate translocation of passenger proteins to the cell surface or to the extracellular environment. .

Transfer of plasmid DNA to M capsulatus by conjugation

Presently conjugation is the only method available for transfer of genetic information to Methylococcus. Conjugative transfer require establishment of physical contact between the cells of the mating-pair, the DNA donor and the DNA recipient. Additionally, the donated plasmids must hold mob or tra genes. The plasmid used, pBBRlMCS-2 (Table 3-3), contained mob genes, while E. coli S 17-1 contained tra genes.

Conjugation was performed as described by Lloyd et al (1999) using the plasmids derived from the mobilizable plasmid pBBRlMCS-2 and the mating-pair donor E. coli S17-1.

M. capsulatus and E. coli whole cells were then separated from the spent medium by centrifugation.

used had a nominal molecular weight limit of 10 kDa and maximum sample volume of 15 ml. Spent medium from a 150 ml cultures was concentrated to a final volume of about 200 μl by repeated centrifugations.

Strategy for cloning

Genetic manipulation in M. capsulatus imposes several constraints regarding systems available for genetic transfer. Conjugation is the only method known to be effective in transferring genes to M. capsulatus, thus the conjugative vector, pBBRlMCS-2, was chosen as carrier of the mutated mopE genes. Based on its successful use in prior conjugations to M. capsulatus, E. coli S 17-1 was chosen as plasmid DNA donor. When this study was initiated expression vectors compatible with M. capsulatus were not available. Thus, to enable initiation of transcription in M. capsulatus, a promoter recognizable by this bacterium was connected to the mutated mopE genes in the conjugative plasmids. Moreover, it was desirable that the transcription should be regulated in a relatively easy manner and this led to use of the mmoX promoter. The mmoX promoter initiate transcription of the M. capsulatus (Bath) operon mmoXYBZYC, and its activity is affected by the concentration of copper. The promoter region used was the 335 bp region located immediately upstream of the start-codon of mmoXYBZYC. This region has been shown to be sufficient for the copper-dependent activity of the promoter.

Construction of the mopE ^H * gene that encodes the MopE ^H * mutant protein

The mopE gene was contained in pAFpglO (Table 3.), and this plasmid was purified from cells from an E. coli DH5α culture. The deletion mutant of the mopE gene was constructed by PCR amplification (Fig. no. 3.) using the forward primer MopE*NcoI (Table 4.) and the reverse primer MopEXhoR (Table 4.). The resulting amplified fragment (Fig. no. 3. and 4.) was -1.2 kb and consisted of a DNA encoding MopE* (GIy ₂₀₅ - PrO ₅₄₀ ), as well as a downstream region containing a Rho-independent transcription terminator. By using primers slightly non-complimentary to their target sequences, flanking Ncol and Xhol recognition sites were introduced in this amplified product. The introduction of the 5' Ncol site resulted in addition of an additional histidine codon to the 5' -end of the mopE* gene. Thus, the amplified gene constructed and the protein encoded by it, was designated mopE ^H * and MopE ^H *, respectively.

The mmoX promoter was present in the plasmid pJBrp2 (Table 3.) linked to the sequence encoding the MopE signal sequence. This plasmid was purified from E. coli DH5α cells (Table 2.), and a fragment containing the mmoX promoter linked to the sequence encoding the MopE signal sequence was amplified from pJBrp2 by the PCR using the primers spNcoI (Table 4.) and sMMOprSacI (Table 4. and Fig. no. 3.). The resulting -0.5 kb DNA product (Fig. no. 4.) was flanked by Sad and Ncol restriction sites.

To simplify handling of the amplified fragments, the two amplification products were individually cloned into pCR ^® 2.1 -TOPO vectors (Table 3.) by TOPO ^® TA cloning producing pCR2.1 -TOPOl and pCR2.1-TOPO2 (Fig. no. 5.). Transformants from both the TOPO ^® TA reactions were selected based on their resistance to ampicillin and impaired production of β-galactosidase. A high yield of transformants was obtained from both transformation reactions.

A few single colonies of transformants were picked and cultivated in liquid LB. Cells from the E. coli TOlOF' cultures were harvested, plasmids were purified and analyzed by Ncol and Sad digestion (Fig. no 4. C). All plasmids purified from the TOPO ^® TA cloning reaction with the -0.5 kb PCR product were digested into three fragments of lengths -0.5 kb, -1.5 kb and -2.5 kb, while all the plasmids purified from the TOPO ^® TA cloning reaction with the -1.2 kb PCR product were digested into three fragments of lengths -1.2 kb, -1.5 kb and -2.5 kb (Fig. no. 4. C lane 1-2, respectively). Thus, the results of the RE-analyses were in agreement with theoretical predictions. One E. coli TOlOF' colony containing pCR2.1-TOPOl and one colony containing pCR2.1-TOPO2 were selected for further analysis. Plasmids from these colonies were purified and sequenced. This sequencing confirmed that the fragment containing the mmoX promoter linked to the MopE signal sequence fragment was contained in pCR ^® 2.1 -TOPOl, and that the fragment containing the mopE ^H * gene was contained in pCR ^® 2.1-TOPO2.

Because of incompatibility of RE-sites in plasmid and fragments, the mopE ^H * gene could not be connected to the mmoX promoter and the sequence encoding the MopE signal sequence directly in the coηjugative vector pBBRlMCS-2. Thus, the fragments should be subcloned in pETl Id (Table 4.). First, the DνA containing the mmoX promoter linked to the sequence encoding the MopE signal sequence should be inserted to pETl Id (Fig. no. 6.) to produce pETl (Table 3.). The DνA containing the mopE ^H * gene then should be inserted to pETl to produce pET2 (Table 3.). Thus, in pET2 the mmoX promoter should precede the mopE ^H * gene connected with an upstream sequence encoding the MopE signal sequence (Fig. no. 2.).

As a first step to construct pETl, both pCR ^® 2.1 -TOPOl and pETl Id were digested by Ncol and Xbal. The restriction of pCR2.1 -TOPOl produced three fragments with lengths -0.5 kb, ~1.7 kb and 2.3 kb, while restriction of pETl Id produced a -5.8 kb fragment, all in agreement with the theoretical predictions. The -0.5 kb DNA containing the mmoX promoter linked to the sequence encoding the MopE signal sequence and the ~5.9 kb vector fragment were purified from the preparative agarose gel (Fig. no. 7. A lane 1-2), and used in a subsequent ligation reaction. The ligation solution was used to transform E. coli TOPlOF' cells and the resulting transformants were selected based on their resistance to ampicillin. One colony of transformed E. coli TOPlOF' cells was obtained. The transformed colony was cultivated in a 5 ml LB culture. A plasmid, designated pETl, was purified from the cells and analysed by RE digestion. The length of pETl was estimated to be about 6.3 kb by agarose gel electrophoresis (Fig. no. 7. B lane 1). In agreement with theoretical predictions pETl to produced two bands, one of length -5.8 kb and one of -0.5 kb after NcoIIXbal double digestion (Fig. no. 7. B lane 2). Insertion of the mmoX promoter and the sequence encoding the MopE signal sequence were verified by sequencing.

To produce pET2 the DNA containing the mopE ^H * gene was inserted to pETl (Fig. no. 8. ). The DNA containing the mopE ^H * gene was excised from pCR ^® 2.1-TOPO2 by digestion with Bamlil and Ncol and this resulted in three fragments with apparent lengths of -1.2 kb, ~1.6 kb and -2.3 kb, as theoretically predicted. The plasmid pETl was opened by digestion with BamHl and Ncol and this resulted in a linear vector fragment of about 6.3 kb.

The -1.2 kb DνA containing the mopE ^H * gene and the -6.3 kb pETl fragment were purified from a preparative agarose gel (Fig. no. 9. A lane 1 and 2, respectively) and used in a subsequent ligation reaction. The ligation solution was used to transform E. coli TOPlOF' cells and transformants were selected based on resistance to ampicillin. A generous number of colonies of transformed E. coli TOPlOF' cells were obtained. A few colonies were picked and cultivated in liquid media for further analysis. Plasmids, designated pET2, were purified from the selected transformed cells and analysed by RE digestion. As predicted theoretically the length of the pET2 was estimated to be -7.4 kb by agarose gel electrophoresis (Fig. no. 9. B lane 1). Double digestion of the plasmid with BamHl and Xbal produced two DνAs, one -1.7 kb and one -5.7 kb fragment (Fig. no. 9. B lane 2), as theoretically predicted. Sequencing confirmed that the mopE ^H * gene, in pET2, was preceded by the mmoX promoter and the sequence encoding the MopE signal sequence.

From pET2 a DNA fragment containing the mopE ^H * gene proceeded by the sequence encoding the MopE signal sequence and the mmoX promoter could be excised and transferred to the mobilizable vector pBBRlMCS-2 (Table 3.). This would produce pBBmopE ^H * (Fig. no. 10.). The pBBmopE ^H * amino acid sequence is shown in the sequence listing, as Seq. ID. no. 9.

This pET2-DNA fragment was excised from the plasmid by restriction with Hindlll and Xbal. As theoretically predicted this resulted in two DNAs, one of ~2.0 kb and one of -5.5 kb. Also as expected, opening of pBBRlMCS-2 by digestion with Hindlll and Xbal produced a ~5.1 kb vector-DNA. The ~5.1 kb vector-DNA was purified from a preparative agarose gel along with the ~2.0 kb pET2-DNA containing the mmoX promoter linked to the sequence encoding the MopE signal sequence and the mopE ^H * gene (Fig. no. 11. A lane 1 and 2) and were ligated. The ligation solution was subsequently used to transform E. coli Top 1OF' cells, and transformed cells were selected based on their resistance to kanamycin. A total of 26 colonies of transformed E. coli Top 1OF' cells were obtained. A few colonies of transformants were cultivated in 5 ml cultures for further analysis.

Plasmids, designated pBBmopE ^H *, were purified from the selected transformed cells and analysed by RE digestion. As theoretically predicted the length of pBBmopE ^H * was estimated to be about 7.2 kb by agarose gel electrophoresis (Fig. no. 11. B lane 2), while double digestion of pBBmopE ^H * with BamHl and Xbal produced two DNAs, a -2.0 kb and a -5.1 kb DNA (Fig. no 11. B lane 1). That pBBmopE ^H * contained a mopE ^H * gene preceded by the mmoX promoter and the sequence encoding the MopE signal sequence was confirmed by sequencing.

Production of MopE ^H * in E. coli S 17-1

A previous study in our laboratory has shown that the mmoX promoter is functional in E. coli. The expression of the mutated mopE ^H * gene was studied in E. coli prior to transfer of the gene to M. capsulatus. E. coli whole cells and spent media were analysed by immunoblotting. E. coli S 17-1 cells harbouring pBBmopE ^H * were harvested from 50 ml cultures and By immunoblotting one immunoreactive protein migrating according to an apparent molecular mass of about 50 kDa was detected (not shown), thus the protein migrated shorter than wild type MopE* in the gel. Thus the E. coli host cell apparently produced MopE ^H *, but the host was not able to cleave off the signal peptide. As

expected no immunoreactive proteins were detected in the E. coli S 17-1 cells harbouring pBBRlMCS-2 (not shown).

Spent medium from a culture of E. coli S 17-1 harbouring pBBmopε ^H * was concentrated. No immunoreactive proteins were detected in the concentrated spent medium. Thus, MopE ^H * were seemingly not secreted from E. coli S 17-1 in detectable amounts. As expected, the E. coli S 17-1 pBBlMCS-2 did not either secrete immunoreactive proteins.

Production of MopE ^H * in M. capsulatus δmopE

The pBBmopE ^H * plasmid was transferred to M. capsulatus:

The plasmid was transferred from E. coli S 17-1 to M capsulatus δmopE by conjugation and M. capsulatus cells transformed by pBBmopE ^H * were selected by their resistance to kanamycin and gentamycin. A total of four coηjugants were obtained. A few were selected for further analysis. The pBBmopE ^H * plasmid was purified from the selected transformants and re-sequencing confirmed that no deletions had occurred during the conjugation process.

To study the expression of MopE ^H * in M. capsulatus the copper-sensitive mmoX promoter was induced by cultivation of M. capsulatus δmopE containing pBBmopE ^H * in a copper-depleted medium. Cells were separated from the spent medium by centrifugation, No MopE proteins could be detected in the M. capsulatus δmopE cells harbouring the empty conjugative plasmid, and no MopE protein was secreted from these cells.

The spent medium was isolated from the M. capsulatus δmopE pBBmopE ^H * cell, concentrated and subjected to SDS-PAGE and immunoblotted. One immunoreactive protein was detected (Fig. no. 12. lane 3). This protein migrated as wild type MopE* (Fig. no. 12. lane 1), demonstrating that MopE ^H * was secreted from M. capsulatus δmopE. Thus, the protein was properly processed in M. capsulatus and was able to cross the OM even though the N-terminal domain had been removed.

In conclusion, MopE ^H * was expressed both in E. coli S 17-1 and in M. capsulatus

δmopE, but the secretion of MopE * was host specific, as MopE * was detected in the

spent medium of the M. capsulatus culture only. This shows conclusively the abillety of MopE ^H * to translocate across the outer membrane of M. capsulatus.

The inventors have in a previous application (Norwegian patent application no. 20033176) established a fusion protein of the complete MopE from M. capsulatus and the VP2 protein in of the infectious pancreatic necrosis (IPN) virus. They have also demonstrated that it is possible to express heterologous peptides in M. capsulatus by using the native protein MopE as a fusion partner. These fusion proteins did translocate, and produced immunological active antibodies.

Cloning of nodavirus capsid - MopEH* fusion proteins

In order to ascertain wether MopE * is able not only to translocate itself, but to do so as a functional fusion protein, several constructs with Nodavirus capsid protein were constructed, and the expression thereof was tested.

Atlantic halibut nodavirus is a RNA virus infecting mitochondria of insects or fish. It infect halibut at the larvae or juvenile stage, and mortality rates are up to 100%. Antibodies against AHNV have been previously developed.

The cloning of the fusion protein constructs were achived by conventional methods, including standard lab methods and commercial kits for cloning, mutagenese, immunoblotting etc, using pBBRlMCS2, as described above, as the starting plasmid. This time, instead of cloning in the MopE ^H * nucleotide sequence alone, the sequence was first modified to comprise capsid protein from Atlantic halibut Nodavirus. In order for the capsid protein DNA sequence to be inserted into the MopEH* sequence, the MopEH* sequence was modified to comprise restriction enzyme sites. One such modified MopEH* sequence contains a BspHI site at the stop codon of MopEH*, another one a Ndel site internally in MopEH*, causing some minor changes in the

MopEH* sequence. The DNA sequences of these two specific modified MopEH* sequences are fiven as Seq. ID no. 16 and 17, respectively. Diagrams thereof are shown in figure 13. Three MopEH* -nodavirus capsid constructs were made, as shown in figure 14.

DNA from Atlantic halibut Nodavirus was a gift from Audun Nerland. Based on the published capsid sequence (Accesion number AJ245641, Seq. ID no 18 in the attatched patentln file) the primers listed in table 6 were ordered from Sigma- Aldrich.

Tableό. List of primers used to create the Atlantic halibut Nodavirus capsid and Mo EH* fusion proteins

Also two new versions of the mopEH* expressions system where made. One version with a BspHl restriction site replacing the stop codon of mopEH* (Seq. ID no 16) and a second version where a Nhel restriction site where mutated into a predicted surface loop of MopEH* (Seq. ID no. 17). The mopEH* plasmids are base don the pBBRl-MCS2 plasmid, and Seq. ID no 19 shows the original, unmodefied pBBRl-mopEH* .

In the first construct, AHNVC-MopEH*, the known sequence of Atlantic halibut

Nodavirus capsid protein (AHNVC) were fused to MopEH* using the Ncol restriction enzyme site at the start of MopEH* giving a protein of 72.4 kDa. The leader sequence should be cleaved off when exported from the cytoplasm giving a protein of 72.5 kDa. The DνA and protein sequences of AHνVC-MopEH* are given as Seq. ID 10 and 11, respectively.

In the second construct, MopEH*-AHνVCc, the predicted surface part of Atlantic halibut Nodavirus capsid protein (AHNVCc) were fused to MopEH* using the BspHl restriction enzyme site at the end of MopEH* giving a protein of 52.5 kDa. The leader sequence should be cleaved off when exported from the cytoplasm giving a protein of 49.5 kDa. The DNA and protein sequences of MopE*-AHNVCc are given as Seq. ID no 12 and 13, respectively.

In the third construct, MopEH*-AHNVC-20, aa a 20 amino acid fragment of Atlantic halibut Nodavirus capsid protein (AHNVC-20aa) were inserted into a predicted surface loop of MopEH* using the Ndel restriction enzyme site giving a protein of 41.5 kDa. The leader sequence should be cleaved off when exported from the cytoplasm giving a protein of 38.5 kDa. The DNA and protein sequences of MopEH*-AHNVC-20aa are given as Seq. ID no 14 and 15, respectively.

Expression of Atlantic halibut Nodavirus capsid MopEH* recombinant proteins

The tree recombinant proteins where conjugated into M. capsulatus AmopEH*. To express the recombinant protein M. capsulatus AmopEH were grown in a low copper medium. At late log phase growth the cultures were harvest and fractionated into:

1 : Spent medium (S)

2: Periplasmic fraction (P)

3: Cytoplasmic fraction (C)

4: Inner membrane (I) 5 : Outer membrane (O)

Figure 15 shows the scheme for localization of the recombinant MopEH*.

The presence of recombinant protein where checked with protein- immunoblot using either AHNV antibodies or MopEH antibodies. The results are given in figure 16. As can bee seen in figure 16 a, for the MopEH*-AHNVCc construct the majority of recombinant MopEH* -AHNVcc was degraded to MopEH*, although some intact fusion protein is left.Fig 16b shows that for the MopEH*-AHNVC 20 aa peptid the MopEH*-AHNVC seems to be misfolded. Figure 16c shows that the AHNVC- MopEH* seems to be intact, allthough the plasmid is a bit unstable.

Figure 17 shows the results of using antibodies against the MopEH* -AHNVC 20 aa peptid. This clearly shows that the translocated MopEH*-AHNVC is antigenic.

In conclusion, the above results thus show that MopEH* fusion proteins can be successfully constructed, and successfully translocated thrugh the outer membrane of M. capsulatus and there expressed.
