DESCRIPTION OF THE TEXT FILE SUBMITTED ELECTRONICALLY

The contents of the text file submitted electronically herewith are incorporated herein by reference in their entirety: A computer readable format copy of the Sequence Listing (filename: MAN-019PC Sequence Listing_ST25; date recorded: September 6, 2019; file size: 235,920 bytes).

BACKGROUND

Rotundone is an oxygenated sesquiterpene (sesquiterpenoid) that is responsible for a pleasing spicy,‘peppery’ aroma in various plants, including grapes (especially syrah or shiraz, mourvedre, durif, vespolina, and griiner veltliner varietals), and a large number of herbs and spices, such as, e.g., black and white pepper, oregano, basil, thyme, marjoram, and rosemary. Given its aroma, rotundone is an attractive molecule for applications in fragrances and flavors. a-Guaiene is the precursor to (-)-rotundone. a-Guaiene is a sesquiterpene hydrocarbon found in oil extracts from various plants, and is converted to (-)-rotundone by aerial oxidation or enzymatic transformation.

Given the commercial value of rotundone, cost effective, scalable, and/or sustainable processes for its production are needed.

SUMMARY

In various aspects, the present disclosure provides methods and compositions for producing rotundone. In various aspects, the present disclosure provides enzymes, polynucleotides encoding said enzymes, and recombinant microbial host cells (or microbial host strains) for the production of rotundone. In some embodiments, the present disclosure provides microbial host cells for producing rotundone at high purity and/or yield, from either enzymatic transformation of a-guaiene, or from sugar or other carbon source. The present disclosure further provides methods of making products containing rotundone, including flavor or fragrance products, among others.

In some embodiments, the present disclosure provides a microbial host cell expressing an enzyme pathway catalyzing the conversion of famesyl diphosphate (FPP) to rotundone, the enzymatic pathway comprising an a-guaiene terpene synthase enzyme (aGTPS) and an a-guaiene oxidase (aGOX) enzyme. In these embodiments, the microbial cells can synthesize rotundone product from any suitable carbon source. In some embodiments, the specificity of the a-guaiene synthase enzyme enables production of rotundone at high yield with fewer terpenoid byproducts. In some embodiments, the aGOX produces rotundone as the predominant oxygenated product.

In some embodiments, the microbial host cell further expresses or overexpresses one or more enzymes in the methylerythritol phosphate (MEP) and/or the mevalonic acid (MV A) pathway to catalyze the conversion of glucose or other carbon sources to isopentenyl pyrophosphate (IPP) and/or dimethylallyl pyrophosphate (DMAPP). In some embodiments, the microbial host cell further expresses an enzyme catalyzing the conversion of IPP and/or DMAPP to famesyl diphosphate (FPP), allowing for rotundone to be produced from sugar or other carbon sources (carbon substrates such as Cl, C2, C3, C4, C5, and/or C6 carbon substrates). In some embodiments, the host cell is a bacteria engineered to increase carbon flux through the MEP pathway.

In some embodiments, the microbial host cell expresses an a-guaiene oxidase (aGOX) enzyme, which may be a P450 enzyme, non-heme iron oxygenase (NHIO), or laccase providing for biotransformation of a-guaiene substrate. a-Guaiene substrate can be added to whole cell or cellular extracts or purified enzyme. In some embodiments, the cell further expresses at least one cytochrome P450 reductase to support P450 enzyme activity for whole cell bioconversion processes. In some embodiments, the aGOX produces rotundone as the predominant oxygenated product.

In some embodiments, the microbial host cell further expresses one or more alcohol dehydrogenases. In some embodiments, the alcohol dehydrogenase converts one or more alcohol intermediates, produced by the reaction of a-guaiene with aGOX, to rotundone. In some embodiments, the microbial host cell is prokaryotic or eukaryotic, and may be a bacteria or yeast.

Other aspects and embodiments of the invention will be apparent from the following detailed disclosure. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 shows the chemical structure of rotundone.

FIG. 2 illustrates a biosynthetic pathway for the production of rotundone. Famesyl diphosphate is converted to a-guaiene by an a-guaiene terpene synthase (aGTPS) enzyme; and a-guaiene is converted to (-)-rotundone by an a-guaiene oxidase (aGOX) enzyme.

FIG. 3 illustrates that the production of (-)-rotundone from a-guaiene can proceed directly from the sesquiterpene precursor, or can involve the production of one or both alcohol intermediates which are subsequently converted to the ketone by an enzyme with alcohol dehydrogenase activity. FIG. 4 shows results from the screening of amino acid substitutions in an exemplary a-guaiene terpene synthase (AcDGuaS3, SEQ ID NO: 8). Derivatives were tested for a-guaiene production in E. coli. The figure shows fold improvement in a- guaiene production.

FIG. 5 lists the altered profile toward production of a-guaiene in E. coli for several amino acid substitutions in AcDGuaS3. Fold improvement of a-guaiene as a % of the total products is listed.

FIG. 6 shows production of a-guaiene with expression of wild-type AcDGuaS3 (a-GS) and mutant AcDGuaS3 having an F406L mutation (a-GSl) in E. coli.

FIGS. 7 A and 7B show production of rotundol and rotundone in E. coli expressing a-GSl and an exemplary CYP450 system (engineered kaurene oxidase; KOeng). Expression of Vitis vinifera dehydrogenase (VvDH) along with a-GSl, KOeng as the a-guaiene oxidase, and Camptotheca acuminata cytochrome P450 reductase (CaCPR) reduces the titer of rotundol (FIG. 7A) and increases rotundone titer (FIG. 7B). FIGS. 8A and B show Gas-Chromatography/Mass Spectrometry (GC/MS) confirmation of production of rotundone from E. coli strain expressing a-GSl, KOeng, CaCPR, and VvDH. FIG. 8 A shows the abundance of rotundone in GC/MS and FIG. 8B shows the gas chromatogram for rotundone. FIG. 9 shows production of rotundol and rotundone in E. coli expressing a-GSl and an alternative CYP450 system. Expression of a-GSl ,Helianthus annuus germacrene A monooxygenase engineered for expression in E. coli (HaGAO), and AaCPR ( Artemisia annua cytochrome P450 reductase) produces primarily rotundone.

FIG. 10 shows a multiple sequence alignment of five kaurene oxygenases, including KOeng (SEQ ID NO: 51), which functions as a-guaiene oxidase enzyme. The homologs are HaKO (SEQ ID NO: 50), AaKO (SEQ ID NO: 49), CcKO (SEQ ID NO: 47), LsKO (SEQ ID NO: 46), and NtKO (SEQ ID NO: 45).

DETAILED DESCRIPTION

In various aspects, the present disclosure provides microbial host cells (or microbial host strains) and methods for producing rotundone and methods of making products containing rotundone, such as flavor and fragrance products, among others. In other aspects, the present invention provides enzymes and polynucleotides encoding enzymes for the production of rotundone.

In some embodiments, the present disclosure provides a microbial host cell, including bacteria and yeast, expressing an enzyme pathway catalyzing the conversion of famesyl diphosphate (FPP) to rotundone. In various embodiments, the enzymatic pathway comprises a a-guaiene synthase enzyme (aGTPS) and an a-guaiene oxidase (aGOX) enzyme. In these embodiments, the microbial cells can synthesize rotundone product from any suitable carbon source. In some embodiments, the specificity of the a- guaiene synthase enzyme enables production of rotundone at high yield with fewer terpenoid byproducts. In some embodiments, the microbial host cell may further expresses one or more alcohol dehydrogenase enzymes (ADH). In some embodiments, the ADH converts one or more alcohol intermediates, produced by the reaction of a- guaiene with aGOX, to rotundone. In some embodiments, the microbial host cell expresses an a-guaiene oxidase (aGOX) enzyme, providing for biotransformation of a-guaiene substrate. In some embodiments, aGOX is a P450 enzyme, non-heme iron oxygenase (NHIO), or laccase. In some embodiments, the cell may further express a cytochrome P450 reductase to support P450 activity. In some embodiments, the microbial host cell may further express one or more alcohol dehydrogenase enzymes (ADH). In some embodiments, the ADH converts one or more alcohol intermediates, produced by the reaction of a-guaiene with aGOX, to rotundone.

Rotundone comprises a guaiene carbon skeleton with a single ketone group in the carbon 2 position (see FIG. 1). a-Guaiene is the precursor to rotundone. a-Guaiene is a sesquiterpene hydrocarbon found in oil extracts from various plants. While a-guaiene can be converted to rotundone by aerial oxidation or enzymatic transformation, these processes are not efficient, in part due to the specificity of enzymes used.

A biosynthetic pathway for rotundone is shown in FIG. 2. The Cl 5 sesquiterpene precursor substrate famesyl diphosphate (FPP) is cyclized to a-guaiene by an aGTPS terpene synthase enzyme. The a-guaiene (i.e., cyclized FPP) is then oxidized to rotundone via an aGOX enzyme. The production of the ketone moiety in a-guaiene resulting in rotundone can proceed directly, or can alternatively proceed through alcohol intermediates, with either stereochemistry of the alcohol intermediate, i.e., (2R)-rotundol or (2S)-rotundol (see FIG. 3).

The aGTPS enzyme is a terpene synthase enzyme (TPS). TPS enzymes are responsible for the synthesis of the terpene molecules from two isomeric 5-carbon precursor building blocks, leading to 5-carbon isoprene, 10-carbon monoterpenes, 15- carbon sesquiterpenes and 20-carbon diterpenes. The structures and functions of TPS enzymes are described in Chen et al, The Plant Journal, 66: 212-229 (2011). Tobacco 5-epi-aristolochene synthase, a terpene synthase, has been described along with structural coordinates, including key active site coordinates. These structural coordinates can be used for constructing homology models of aGTPS enzymes, which are useful for guiding the engineering of aGTPS enzymes with improved specificity and productivity. See, US 6,645,762, US 6,495,354, and US 6,645,762, which are hereby incorporated by reference in their entireties. In some embodiments, the TPS enzyme is selected from Vitis vinifera GuaS (VvGuas) enzyme (SEQ ID NO: 1), patchouli synthase (PcPS) enzyme from Pogostemon cablin (Uniprot Q49SP3) (SEQ ID NO: 2), Vitis vinifera germacrene D synthase (VvGDS; NCBI Ref #XP_002282488.1) (SEQ ID NO: 21), or a variant thereof In some embodiments, the TPS enzyme is selected from Aquilaria crassna, for example, AcCl (Uniprot D0VMR5); AcC2 (Uniprot D0VMR6) (SEQ ID NO: 3); AcC3 (Uniprot D0VMR7) (SEQ ID NO: 4); or AcC4 (Uniprot D0VMR8) (SEQ ID NO: 5), or a variant thereof.

In some embodiments, the a-guaiene synthase enzyme comprises an amino acid sequence that has at least about 60% sequence identity, or at least about 70% sequence identity, or at least about 80% sequence identity, or at least about 90% sequence identity, or at least about 95% sequence identity, or at least about 98% sequence identity, or at least about 99% sequence identity with the amino acid sequence of any one SEQ ID NOs: 1, 3, 4, 6 to 10, 11 to 15, or 19. In some embodiments, the a-guaiene synthase enzyme includes from 1 to about 20, or from 1 to about 10, or from 1 to about 5 amino acid modifications independently selected from substitutions, deletions, and insertions to an amino acid sequence selected from SEQ ID NOs: 1, 3, 4, 6 to 10, 11 to 15, or 19.

In some embodiments, the a-guaiene synthase enzyme comprises an amino acid sequence that has 50% or more sequence identity with SEQ ID NO: 8. In some embodiments, the a-guaiene synthase enzyme comprises an amino acid sequence that has at least about 60% sequence identity, or at least about 70% sequence identity, or at least about 80% sequence identity, or at least about 90% sequence identity, or at least about 95% sequence identity, or at least about 98% sequence identity, or at least about 99% sequence identity with the amino acid sequence of SEQ ID NO: 8.

In some embodiments, the a-guaiene synthase may have one, two, three, four, five or more amino acid substitutions at positions corresponding to positions selected from 72, 273, 290, 368, 371, 374, 377, 381, 382, 399, 406, 419, 433, 442, 443, 454, 512, and 522 of SEQ ID NO: 8. For example, in some embodiments the a-GTPS comprises an amino acid sequence having one or more (e.g, 2, 3, 4, 5, or all) of the amino acid substitutions selected from T72I, M273L, R290K, F368M, 1371L, S374A, R377V, Y381W, F382L, I399V, F406L, L419T, V433I, Y442L, I443M, E454K, F512L, and K522D relative to SEQ ID NO: 8. In some embodiments, the a-GTPS includes an amino acid substitution at the position corresponding to position 406 of SEQ ID NO: 8, and which is optionally F406L, F406A, F406I, F406V, or F406G. In some embodiments, the a-GTPS enzyme includes an amino acid substitution at the position corresponding to position 443 of SEQ ID NO: 8, which is optionally I443M. In some embodiments, the a- GTPS enzyme includes a mutation at the position corresponding to position 512 of SEQ ID NO: 8, which is optionally F512L, F512A, F512I, F512V, or F512G Amino acid substitutions may be conservative or non-conservative substitutions.

“Conservative substitutions” may be made, for instance, on the basis of similarity in polarity, charge, size, solubility, hydrophobicity, hydrophilicity, and/or the amphipathic nature of the amino acid residues involved. The 20 naturally occurring amino acids can be grouped into the following six standard amino acid groups: (1) hydrophobic: Met, Ala, Val, Leu, Ile;

(2) neutral hydrophilic: Cys, Ser, Thr; Asn, Gln;

(3) acidic: Asp, Glu;

(4) basic: His, Lys, Arg;

(5) residues that influence chain orientation: Gly, Pro; and (6) aromatic: Trp, Tyr, Phe.

As used herein, "conservative substitutions" are defined as exchanges of an amino acid by another amino acid listed within the same group of the six standard amino acid groups shown above. For example, the exchange of Asp by Glu retains one negative charge in the so modified polypeptide. In addition, glycine and proline may be substituted for one another based on their ability to disrupt a-helices. Some preferred conservative substitutions within the above six groups are exchanges within the following sub-groups: (i) Ala, Val, Leu and Ile; (ii) Ser and Thr; (ii) Asn and Gln; (iv) Lys and Arg; and (v) Tyr and Phe.

As used herein,“non-conservative substitutions” or“non-conservative amino acid exchanges” are defined as exchanges of an amino acid by another amino acid listed in a different group of the six standard amino acid groups (1) to (6) shown above. Mutations in a-GTPS enzymes can be guided by homology models using molecular structures/models of sesquiterpene synthase disclosed in Drew et al, J. of Exp. Botany, Vol. 67, No. 3, pp. 799-808 (2015) and/or Kumeta et al, Plant Physiology, Vol. 154, pp. 1998-2007 (2010), which are hereby incorporated by reference in its entirety.

The similarity of nucleotide and amino acid sequences, i.e. the percentage of sequence identity, can be determined via sequence alignments. Such alignments can be carried out with several art-known algorithms, such as with the mathematical algorithm of Karlin and Altschul (Karlin & Altschul (1993) Proc. Natl. Acad. Sci. USA 90: 5873- 5877), with hmmalign (HMMER package, http://hmmer.wustl.edu/) or with the CLUSTAL algorithm (Thompson, J. D., Higgins, D. G. & Gibson, T. J. (1994) Nucleic Acids Res. 22, 4673-80). The grade of sequence identity (sequence matching) may be calculated using e.g. BLAST, BLAT or BlastZ (or BlastX). A similar algorithm is incorporated into the BLASTN and BLASTP programs of Altschul et al (1990) J. Mol. Biol. 215: 403-410. BLAST protein searches may be performed with the BLASTP program, score=50, word length=3. To obtain gapped alignments for comparative purposes, Gapped BLAST is utilized as described in Altschul et al (1997) Nucleic Acids Res. 25: 3389-3402. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs are used. Sequence matching analysis may be supplemented by established homology mapping techniques like Shuffle-LAGAN (Brudno M., Bioinformatics 2003b, 19 Suppl 1 : 154-162) or Markov random fields.

TPS enzymes can generate multiple products with the guaiene skeleton from FPP with varied amounts of a-guaiene produced by different TPS enzymes. In some embodiments, the a-guaiene synthase (or engineered variant) produces predominantly a- guaiene (e.g., greater than 50%) as the product from FPP substrate. In some embodiments, the a-guaiene synthase produces greater than about 75%, or greater than about 80%, or greater than about 85%, or greater than about 90%, or greater than about 95% a-guaiene as the product from FPP. Enzyme specificity can be determined in host microbial cells producing FPP and expressing the a-guaiene synthase, followed by chemical analysis of total terpenoid products. In some embodiments, the a-guaiene produced in the aGTPS reaction is oxidized to rotundone. In some embodiments, an aGOX enzyme oxidizes a-guaiene to rotundone. In some embodiments, the aGOX oxidizes at least one portion of the a-guaiene to a ketone. In some embodiments, the oxidation of a-guaiene by aGOX results in the production of one or more alcohol intermediates. In some embodiments, the alcohol intermediates are converted to rotundone by one or more alcohol dehydrogenases.

In some embodiments, the aGOX enzyme is a cytochrome P450 (CYP450) enzyme. CYP450 enzymes are involved in the formation (synthesis) and breakdown (metabolism) of various molecules and chemicals within cells. CYP450 enzymes have been identified in all kingdoms of life (i.e., animals, plants, fungi, protists, bacteria, archaea, and even in viruses). Illustrative structure and function of CYP450 enzymes are described in Uracher et al, TRENDS in Biotechnology , 24(7): 324-330 (2006). In some embodiments, the P450 enzymes are engineered to have a deletion of all or part of the wild type N-terminal transmembrane region, and the addition of a transmembrane domain derived from an E. coli inner membrane cytoplasmic C-terminus protein. In various embodiments, the transmembrane domain is a single-pass transmembrane domain. In various embodiments, the transmembrane domain (or“N-terminal anchor”) is derived from an E. coli gene selected from waaA, ypfN, yhcB, yhbM, yhhm, zipA, ycgG, djlA, sohB, lpxK, Fl lO, motA, htpx, pgaC, ygdD, hemr, and yds. These genes were identified as inner membrane cytoplasmic C-terminus proteins through bioinformatic prediction as well as experimental validation. The invention may employ an N-terminal anchor sequence that is a derivative of the E. coli wild-type transmembrane domain, that is, having one or more mutations (e.g., amino acid substitutions) with respect to the wild-type sequence. Methods of making such engineered P450 enzymes as well as engineered P450 enzymes are described in U.S. Patent Publication No. 2018/0251738, which is hereby incorporated by reference in its entirety.

In some embodiments, the CYP450 is selected from the V. vinifera VvST02 (CYP71BE5; Uniprot F6I534) (SEQ ID NO: 22); Bacillus subtilis CYP152A1 (Uniprot 031440) (SEQ ID NO: 23); B. subtilis CYP107K1 (Uniprot A5HNX5) (SEQ ID NO: 24); Bacillus cereus CYP106 (Uniprot Q737I9) (SEQ ID NO: 25); and B. cereus CYP107 (Uniprot Q737F2) (SEQ ID NO: 26); or a variant thereof. aGOX variants include enzymes comprising an amino acid sequence that has 50% or more sequence identity with any one of SEQ ID NOS: 22 to 26. In some embodiments, the variant comprises an amino acid sequence that has at least about 60% sequence identity, or at least about 70% sequence identity, or at least about 80% sequence identity, or at least about 90% sequence identity, or at least about 95% sequence identity, or at least about 98% sequence identity, or at least about 99% sequence identity with the amino acid sequence of any one SEQ ID NOS: 22 to 26. In some embodiments, the variant includes from 1 to about 20, or from 1 to about 10, or from 1 to about 5 amino acid modifications independently selected from substitutions, deletions, and insertions to an amino acid sequence selected from SEQ ID NO: 22 to 26. In some embodiments, the oxygenase comprises a substitution to one or more of the substrate binding site or active site. In some embodiments, modifications to enzymes can be informed by construction of a homology model. In some embodiments, selection and modification of enzymes is informed by assaying activity on a-guaiene substrate. In some embodiments, the amino acid modifications can be selected to improve one or more of: enzyme productivity, selectivity for the desired substrate and/or product, stability, temperature tolerance, and expression.

In some embodiments, the aGOX enzyme is a non-heme iron oxygenase (NHIO) or a laccase. In some embodiments, the laccase is derived from bacteria or fungi (including filamentous fungi and yeasts). By way of example, in some embodiments, the laccase is from a species selected from Aspergillus, Neurospora (e.g., N. crassa), Podospora, Botrytis, Collybia, Fomes, Lentinus, Lentinus, Pleurotus, Trametes, Rhizoctonia (e.g., R. solani), Coprinus (e.g., C. plicatilis), P satyr ella, Myceliophtera (e.g., M. thermophila), Schytalidium, and Polyporus, (e.g., P. pinsitus), Phiebia, and Coriolus, or is a derivative thereof.

In some embodiments, the CYP450 (aGOX) comprises an amino acid sequence that has at least 50% identity to SEQ ID NO: 51. In some embodiments, the CYP450 enzyme comprises an amino acid sequence that is at least about 55%, or at least about 60%, or at least about 65%, or at least about 70%, or at least about 75%, or at least about 80%, or at least about 85%, or at least about 90%, or at least about 95%, or at least 98%, or at least 99% identical to SEQ ID NO: 51. For example, the CYP450 enzyme may comprise an amino acid sequence having from 1 to 20 or from 1 to 10 amino acid modifications with respect to SEQ ID NO: 51, the amino acid modifications being independently selected from amino acid substitutions, deletions, and insertions with respect to corresponding positions in SEQ ID NO: 51. In some embodiments, the CYP450 comprises an amino acid sequence that has at least 50% identity to SEQ ID NO: 52. In some embodiments, the CYP450 enzyme comprises an amino acid sequence that is at least about 55%, or at least about 60%, or at least about 65%, or at least about 70%, or at least about 75%, or at least about 80%, or at least about 85%, or at least about 90%, or at least about 95%, or at least 98%, or at least 99% identical to SEQ ID NO: 52. For example, the CYP450 enzyme may comprise an amino acid sequence having from 1 to 20 or from 1 to 10 amino acid modifications with respect to SEQ ID NO: 52, the amino acid modifications being independently selected from amino acid substitutions, deletions, and insertions with respect to corresponding positions in SEQ ID NO: 52.

In some embodiments, the CYP450 comprises an amino acid sequence that has at least 50% identity to SEQ ID NOs: 54, 55, or 56. In some embodiments, the CYP450 enzyme comprises an amino acid sequence that is at least about 55%, or at least about 60%, or at least about 65%, or at least about 70%, or at least about 75%, or at least about 80%, or at least about 85%, or at least about 90%, or at least about 95%, or at least 98%, or at least 99% identical to SEQ ID NOs: 54, 55, or 56. For example, the CYP450 enzyme may comprise an amino acid sequence having from 1 to 20 or from 1 to 10 amino acid modifications with respect to SEQ ID NO: 54, 55, or 56, the amino acid modifications being independently selected from amino acid substitutions, deletions, and insertions with respect to corresponding positions in SEQ ID NO: 54, 55, or 56.

Amino acid modification to CYP450 enzymes can be guided by available structures, including those described in Pallan el al,“Structural and kinetic basis of steroid 17a, 20-lyase activity in teleost fish cytochrome P450 17A1 and its absence in cytochrome P450 17A2,” Journal of Biological Chemistry 290.6 (2015): 3248-3268, which is hereby incorporated by reference in its entirety. Pallan et al. describe a Zebra fish cytochrome P450 17A2 along with structural coordinates, including key active site coordinates. These structural coordinates can be used for constructing homology models of CYP450 enzymes, which are useful for guiding the engineering of CYP450 enzymes with improved specificity and productivity.

In some embodiments, the CYP450 enzyme requires the presence of an electron transfer protein capable of transferring electrons to the CYP450 protein. In some embodiments, this electron transfer protein is a cytochrome P450 reductase (CPR), which can be expressed by the microbial host cell. Various reductases that may be used are described in U.S. Patent Publication No. 2018/0135081, which is hereby incorporated by reference in its entirety.

Exemplary P450 reductase enzymes include those shown herein as SEQ ID NOs: 27 to 34 or 53, or a variant thereof. Variants generally include enzymes comprising an amino acid sequence that has 50% or more sequence identity with any one of SEQ ID NOs: 27 to 34 or 53. In some embodiments, the variant comprises an amino acid sequence that has at least about 60% sequence identity, or at least about 70% sequence identity, or at least about 80% sequence identity, or at least about 90% sequence identity, or at least about 95% sequence identity, or at least about 98% sequence identity, or at least about 99% sequence identity with the amino acid sequence of any one SEQ ID NOs: 27 to 34 or 53.

In some embodiments, the aGOX reaction results in hydroxylation of a-guaiene, thereby producing one or more alcohol intermediates, e.g., (2R)-rotundol or (2S)- rotundol (see FIG. 3). In some embodiments, the aGOX further oxidizes at least a portion of the a-guaiene to a ketone. In some embodiments, the alcohol intermediates (e.g., (2R)- rotundol or (2S)-rotundol) are converted to rotundone by one or more alcohol dehydrogenases (ADHs). Thus, in some embodiments, the microbial host cell expresses one or more alcohol dehydrogenases (ADH). By way of example, in some embodiments, the ADH is selected from an enzyme comprising an amino acid sequence selected from SEQ ID NOs: 35 to 44, or a variant thereof. Variants generally include enzymes comprising an amino acid sequence that has 50% or more sequence identity with any one of SEQ ID NOs: 35 to 44. In some embodiments, the variant comprises an amino acid sequence that has at least about 60% sequence identity, or at least about 70% sequence identity, or at least about 80% sequence identity, or at least about 90% sequence identity, or at least about 95% sequence identity, or at least about 98% sequence identity, or at least about 99% sequence identity with the amino acid sequence of any one SEQ ID NOS: 35 to 44. In some embodiments, the variant includes from 1 to about 20, or from 1 to about 10, or from 1 to about 5 amino acid modifications independently selected from substitutions, deletions, and insertions to an amino acid sequence selected from SEQ ID NO: 35 to 44. In some embodiments, the amino acid modifications can be selected to improve one or more of: enzyme productivity, selectivity for the desired substrate and/or product, stability, temperature tolerance, and expression.

In some embodiments, the ADH comprises an amino acid sequence that has at least 50% identity to SEQ ID NO: 43 (VvDH). In some embodiments, the ADH enzyme comprises an amino acid sequence that is at least about 55%, or at least about 60%, or at least about 65%, or at least about 70%, or at least about 75%, or at least about 80%, or at least about 85%, or at least about 90%, or at least about 95%, or at least 98%, or at least 99% identical to SEQ ID NO: 43. For example, the ADH enzyme may comprise an amino acid sequence having from 1 to 20 or from 1 to 10 amino acid modifications with respect to SEQ ID NO: 43, the amino acid modifications being independently selected from amino acid substitutions, deletions, and insertions with respect to corresponding positions in SEQ ID NO: 43.

In some embodiments, the microbial cell expresses an aGOX, and produces predominately rotundone (e.g., at least 75% of the oxygenated product is rotundone), without expression of an ADH enzyme.

In various embodiments, the aGTPS and aGOX are expressed together in an operon, or are expressed individually. The enzymes may be expressed from extrachromosomal elements such as plasmids, or bacterial artificial chromosomes, or may be chromosomally integrated. In some embodiments, the cell does not express an aGTPS, but expresses an a- guaiene oxidase (aGOX), allowing enzymatic biotransformation of a-guaiene, which can take place with whole cells or whole or partially purified extracts of cells.

In some embodiments, the aGOX and/or the ADH are provided in a purified recombinant form for production of rotundone from a-guaiene, or (2R)-rotundol or (2S)- rotundol, in a cell free system.

In some embodiments, the microbial host cell is also engineered to express or overexpress one or more enzymes in the methylerythritol phosphate (MEP) and/or the mevalonic acid (MV A) pathway to catalyze isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP) from glucose or other carbon source.

In some embodiments, the microbial host cell is engineered to express or overexpress one or more enzymes of the MEP pathway. In some embodiments, the MEP pathway is increased and balanced with downstream pathways by providing duplicate copies of certain rate-limiting enzymes. The MEP (2-C-methyl-D-erythritol 4- phosphate) pathway, also called the MEP/DOXP (2-C-methyl-D-erythritol 4- phosphate/l-deoxy-D-xylulose 5-phosphate) pathway or the non-mevalonate pathway or the mevalonic acid-independent pathway refers to the pathway that converts glyceraldehyde-3-phosphate and pyruvate to IPP and DMAPP. The pathway typically involves action of the following enzymes: l-deoxy-D-xylulose-5-phosphate synthase (Dxs), l-deoxy-D-xylulose-5-phosphate reductoisomerase (IspC), 4-diphosphocytidyl- 2-C-methyl-D-erythritol synthase (IspD), 4-diphosphocytidyl-2-C-methyl-D-erythritol kinase (IspE), 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase (IspF), l-hydroxy- 2-methyl-2-(E)-butenyl 4-diphosphate synthase (IspG), and isopentenyl diphosphate isomerase (IspH). The MEP pathway, and the genes and enzymes that make up the MEP pathway, are described in US 8,512,988, which is hereby incorporated by reference in its entirety. For example, genes that make up the MEP pathway include dxs, ispC, ispD, ispE, ispF, ispG, ispH, idi, and ispA. In some embodiments, the microbial host cell expresses or overexpresses of one or more of dxs, ispC, ispD, ispE, ispF, ispG, ispH, idi, ispA, or modified variants thereof, which results in the increased production of IPP and DMAPP. In some embodiments, rotundone is produced at least in part by metabolic flux through an MEP pathway, and wherein the microbial host cell has at least one additional gene copy of one or more of dxs. ispC, ispD, ispE, ispF, ispG, ispH, idi, ispA, or modified variants thereof.

In some embodiments, the microbial host cell is engineered to express or overexpress one or more enzymes of the MVA pathway. The MVA pathway refers to the biosynthetic pathway that converts acetyl-CoA to IPP. The mevalonate pathway typically comprises enzymes that catalyze the following steps: (a) condensing two molecules of acetyl-CoA to acetoacetyl-CoA (e.g., by action of acetoacetyl-CoA thiolase); (b) condensing acetoacetyl-CoA with acetyl-CoA to form hydroxymethylglutaryl- CoenzymeA (HMG-CoA) (e.g., by action of HMG-CoA synthase (HMGS)); (c) converting HMG-CoA to mevalonate (e.g., by action of HMG-CoA reductase (HMGR)); (d) phosphorylating mevalonate to mevalonate 5-phosphate (e.g., by action of mevalonate kinase (MK)); (e) converting mevalonate 5-phosphate to mevalonate 5- pyrophosphate (e.g., by action of phosphomevalonate kinase (PMK)); and (f) converting mevalonate 5 -pyrophosphate to isopentenyl pyrophosphate (e.g., by action of mevalonate pyrophosphate decarboxylase (MPD)). The MVA pathway, and the genes and enzymes that make up the MVA pathway, are described in US 7,667,017, which is hereby incorporated by reference in its entirety. In some embodiments, the microbial host cell expresses or overexpresses one or more of acetoacetyl-CoA thiolase, HMGS, HMGR, MK, PMK, and MPD or modified variants thereof, which results in the increased production of IPP and DMAPP. In some embodiments, rotundone is produced at least in part by metabolic flux through an MVA pathway, and wherein the microbial host cell has at least one additional gene copy of one or more of acetoacetyl-CoA thiolase, HMGS, HMGR, MK, PMK, MPD, or modified variants thereof.

In some embodiments, the microbial host cell is engineered to increase production of IPP and DMAPP from glucose as described in PCT Application Nos. PCT/US2018/016848 and PCT/US2018/015527, the contents of which are hereby incorporated by reference in their entireties. For example, in some embodiments the microbial host cell overexpresses MEP pathway enzymes, with balanced expression to push/pull carbon flux to IPP and DMAPP. In some embodiments, the microbial host cell is engineered to increase the availability or activity of Fe-S cluster proteins, so as to support higher activity of IspG and IspH, which are Fe-S enzymes. In some embodiments, the host cell is engineered to overexpress IspG and IspH, so as to provide increased carbon flux to l-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBPP) intermediate, but with balanced expression to prevent accumulation of HMBPP at an amount that reduces cell growth or viability, or at an amount that inhibits MEP pathway flux. Conversion of IPP and DMAPP precursors to famesyl diphosphate (FPP) is typically through the action of a famesyl diphosphate synthase (FPPS). Exemplary FPPS enzymes are disclosed in US 2018/0135081, which is hereby incorporated by reference in its entirety.

In some embodiments, the host cell is engineered to downregulate the ubiquinone biosynthesis pathway, e.g., by reducing the expression or activity of IspB, which uses IPP and FPP substrate.

In some embodiments, the microbial host cell is a bacteria selected from Escherichia spp., Bacillus spp., Corynebacterium spp., Rhodobacter spp., Zymomonas spp., Vibrio spp., and Pseudomonas spp. For example, in some embodiments, the bacterial host cell is a species selected from Escherichia coli, Bacillus subtilis, Corynebacterium glutamicum, Rhodobacter capsulatus, Rhodobacter sphaeroides, Zymomonas mobilis, Vibrio natriegens, or Pseudomonas putida. In some embodiments, the bacterial host cell is E. coli.

In some embodiments, the microbial host cell is a species of Saccharomyces, Pichia, or Yarrowia, including, but not limited to, Saccharomyces cerevisiae, Pichia pastoris, and Yarrowia lipolytica.

In another aspect, the present disclosure provides a method for making rotundone. The method comprises providing a microbial host cell (or microbial host strain) as disclosed herein. The microbial host cell expresses an aGOX enzyme, and optionally an aGTPS enzyme as described herein. Cells expressing an aGOX enzyme can be used for bioconversion of a-guaiene using whole cells or cell extracts. Cells expressing an aGOX enzyme and an aGTPS enzyme can produce rotundone from a carbon source.

In some embodiments, the microbial host cell further expresses one or more alcohol dehydrogenases (ADHs) disclosed herein. Cells expressing ADHs can convert alcohol intermediates produced by the aGOX reaction into rotundone. In some embodiments, the host cell is cultured to produce rotundone. In some embodiments, microbial cells are cultured with carbon substrates (sources) such as Cl, C2, C3, C4, C5, and/or C6 carbon substrates. In exemplary embodiments, the carbon source is glucose, sucrose, fructose, xylose, and/or glycerol. Culture conditions are generally selected from aerobic, microaerobic, and anerobic.

In various embodiments, the host cell is cultured at a temperature between 22° C and 37° C. While commercial biosynthesis in bacteria such as E. coli can be limited by the temperature at which overexpressed and/or foreign enzymes (e.g., enzymes derived from plants) are stable, recombinant enzymes (including the terpenoid synthase) may be engineered to allow for cultures to be maintained at higher temperatures, resulting in higher yields and higher overall productivity. In some embodiments, the host cell is a bacterial host cell, and culturing is conducted at about 22° C or greater, about 23° C or greater, about 24° C or greater, about 25° C or greater, about 26° C or greater, about 27° C or greater, about 28° C or greater, about 29° C or greater, about 30° C or greater, about 31° C or greater, about 32° C or greater, about 33° C or greater, about 34° C or greater, about 35° C or greater, about 36° C or greater, or about 37° C.

Rotundone can be extracted from media and/or whole cells, and recovered. In some embodiments, the oxygenated rotundone product is recovered and optionally enriched by fractionation (e.g. fractional distillation). The oxygenated product can be recovered by any suitable process, including partitioning the desired product into an organic phase. The production of the desired product can be determined and/or quantified, for example, by gas chromatography (e.g., GC-MS). The desired product can be produced in batch or continuous bioreactor systems. Production of product, recovery, and/or analysis of the product can be done as described in US 2012/0246767, which is hereby incorporated by reference in its entirety. For example, in some embodiments, oxidized oil is extracted from aqueous reaction medium, which may be done by partitioning into an organic phase, followed by fractional distillation. Sesquiterpene and sesquiterpenoid components of fractions may be measured quantitatively by GC/MS, followed by blending of the fractions.

In some embodiments, the microbial host cells and methods disclosed herein are suitable for commercial production of rotundone, that is, the microbial host cells and methods are productive at commercial scale. In some embodiments, the size of the culture is at least about 100 L, at least about 200 L, at least about 500 L, at least about 1,000 L, at least about 10,000 L, at least about 100,000 L, or at least about 1,000,000 L. In some embodiment, the culturing may be conducted in batch culture, continuous culture, or semi-continuous culture.

In some aspects, the present disclosure provides methods for making a product comprising rotundone, including flavor and fragrance compositions or products. In some embodiments, the method comprises producing rotundone as described herein through microbial culture, recovering the rotundone, and incorporating the rotundone into the flavor or fragrance composition, or a consumable product (e.g., a food product).

As used in this specification and the appended claims, the singular forms“a”, “an” and“the” include plural referents unless the content clearly dictates otherwise. For example, reference to“a cell” includes a combination of two or more cells, and the like.

As used herein, the term“about” in reference to a number is generally taken to include numbers that fall within a range of 10% in either direction (greater than or less than) of the number.

EXAMPLES

Rotundone is a bicyclic sesquiterpene (FIG. 1) and is responsible for pepper aromas in grapes and wine and in herbs and spices, especially black and white pepper, where it has a high odor activity value (OAV). The biosynthesis of rotundone involves cyclization of the Cl 5 sesquiterpene precursor substrate famesyl diphosphate (FPP) to a-guaiene by an a-GTPS terpene synthase (FIG. 2). Enzymatic oxygenation of a-guaiene can produce rotundone, and may proceed through an alcohol intermediate (FIGS. 2 and 3). For example, a-guaiene may be converted to (2S)-rotundol or (2R)-rotundol by the action of aGOX, and the alcohol intermediate(s) (rotundol) can be converted to rotundone by the action of the aGOX or an alcohol dehydrogenase.

Example 1: Engineering q-Guaiene Synthase to Improve a-Guaiene Production

The a-guaiene precursor, rotundol, or rotundone can be produced by biosynthetic fermentation processes, using microbial strains that produce high levels of MEP pathway products, along with heterologous expression of rotundone biosynthesis enzymes, including, enzymes that catalyze 1) cyclization of FPP to a-guaiene; 2) oxidation of a- guaiene to rotundone, which can include 3) dehydrogenation of rotundol to rotundone. For example, in bacteria such as E. coli, isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP) can be produced from glucose or other carbon source, and which can be converted to famesyl diphosphate (FPP) by recombinant famesyl diphosphate synthase (FPPS). FPP is converted to a-guaiene by a-guaiene synthase (aGTPS) by cyclization. The a-guaiene is converted to rotundol or rotundone by oxygenation reaction catalyzed by an a-guaiene oxidase (aGOX). In instances where the aGOX enzyme catalyzes the production of (2S)-rotundol or (2R)-rotundol from a- guaiene, the conversion of rotundol to rotundone may be catalyzed by a dehydrogenase.

Using an E. coli background strain that produces high levels of the MEP pathway products IPP and DMAPP (see US 2018/0245103 and US 2018/0216137, which are hereby incorporated by reference), candidate aGTPS enzymes were screened by co expression with FPPS. Fermentation was performed in 96 well plates for 48 hours. The following synthase enzymes demonstrated production of a-guaiene in E. coli : AcC 1 mut 1 _M42, AcClmut2_M50, AcC2, AcC3, AcDGuaS2, AcDGuaS3, AcDGuaS4, AcDGuaS5, AmaDGuaSl, AmiDGuaSl, AmiDGuaS2, AmiDGuaS3, AsDGuaS3, PcPS, and VvGuaS. In addition to the desired a-guaiene product, active enzymes had varying product profiles. For example, all active Aquilaria enzymes showed a-bulnesene as a major product with a-guaiene. VvGuaS accumulated a-bulnesene and globulol in similar levels to a-guaiene. AcDGuaS3 was selected for subsequent studies based on its productivity and product profile.

A panel of amino acid substitutions to the AcDGuaS3 sequence were screened for their ability to convert FPP to a-guaiene in E. coli. The fermentation was conducted in 96 well plates for 48 hours. FIG. 4 shows several mutants (i.e., amino acid substitutions) and the associated fold-improvement in a-guaiene production. For example, F406L substitution in AcDGuaS3 demonstrated a significantly improved titer of a-guaiene (1.71 fold higher than wild-type). Amino acid substitutions were further evaluated for substitutions that shift the product profile toward a-guaiene. See FIG. 5. As shown, a single substitution in wild-type AcDGuaS3 (I443M) shows a 2.4 fold improvement in % a-guaiene relative to other products. Similarly, a F406L substitution shows a 2.12 fold improvement in % a-guaiene relative to other products. A F512 mutation demonstrated a 1.23 fold improvement in % a-guaiene relative to other products. FIG. 6 shows the fold improvement in titer of a-guaiene, based on expression of a variant having an F406L substitution in AcDGuaS3 (a-GSl) as compared to the parent enzyme.

Example 2: Production of Rotundone

Candidate a-guaiene oxidase enzymes where screened by co-expression in E. coli with FPPS and a-GSl. Production of rotundol and rotundone were observed with expression of an engineered Kaurene Oxidase (KOeng). See, US 2018/0135081, which is hereby incorporated by reference in its entirety. Co-expression of Vitis vinifera dehydrogenase (VvDH) along with a-GSl, KOeng, and Camptotheca acuminata cytochrome P450 reductase (CaCPR) reduces the titer of rotundol (FIG. 7A) and increases rotundone titer (FIG. 7B). Rotundone derived from oxidation of a-guaiene by cytochrome P450 was confirmed by GC/MS (FIG. 8A and 8B). The KOeng can be further engineered to improve specificity for the a-guaiene substrate. An alignment with wild-type kaurene oxidase enzymes is shown in Example 10, which can assist this engineering.

Figure 9 shows in vivo production of rotundol and rotundone using an alternative CYP450 system, based on expression of Helianthus annuus germacrene A monooxygenase (HaGAO). The A. coli strain included expression of a-GSl, engineered HaGAO for expression in E. coli (SEQ ID NO:52), and AaCPR ( Artemisia annua cytochrome P450 reductase; SEQ ID NO: 33). The fermentation was conducted in 96 well plates for 48 hours. As shown in FIG. 9, the oxygenated product was substantially rotundone, with only minor amounts of the rotundol intermediate.
