FIELD OF THE INVENTION
The invention relates to the fields of microbiology and molecular biology. In particular, the invention relates to the field of mycology and the production of secondary metabolites from fungi.
SUMMARY OF THE RELATED ART
Secondary metabolites are a major source of commercially useful products such as food additives, vitamins, and medicines for the treatment of a wide variety of infections and diseases. By way of example, in 1997 the statin drugs lovastatin, simvastatin, and pravastatin, fungal secondary metabolites used in the treatment of hypercholesteremia, together had US sales of US$7.53 billion (Sutherland et al., Current Opinion In Drug Discovery & Development 4:229–236 (2001)). The cost and availability of these plant, bacterial and fungal metabolites are frequently determined by limitations imposed on production and purification of these compounds from culture. This problem is frequently exacerbated by the fact that these products are generally produced during the stationary phase of bacterial and fungal growth.
A wide variety of methods have been utilized to increase the amount of secondary metabolite produced in culture. Studies have demonstrated the importance of carefully designing the medium in which a fungus is grown to maximize the amount of a secondary metabolite produced (see, e.g., Hajjaj H, et al., Appl. Environ. Microbiol. 67:2596–602 (2001); Lesova, K., et al., J. Basic Microbiol. 40:369–75 (2000)). In addition, the method of culture or fermentation also impacts directly on the amount of secondary metabolite produced. For example, see Robinson, T., et al. (Appl. Microbiol. Biotechnol. 55:284–289 (2001)), which demonstrates the advantages of solid state (substrate) fermentation.
In addition to the manipulation of culture and media conditions, genetic approaches have been taken to increase secondary metabolite production. For example, the production of penicillin is limited by the activity of two enzymes, encoded by the ipnA and acvA genes, both of which are regulated by the pacC protein, a zinc-finger transcription factor. Naturally occurring mutant alleles of the pacC locus are known to possess more transcription-activating activity than the cognate, wild-type allele (see, e.g., Tilburn et al. EMBO J. 14(4):779–790 (1995)). Thus, one genetic approach to increasing secondary metabolite production is to identify and isolate naturally occurring mutant alleles, the expression of which leads to increased secondary metabolite production.
Although many regulators of secondary metabolite production in many organisms are known, not all of the organisms that produce secondary metabolites are amenable to genetic or molecular genetic manipulation. Thus, these systems are not generally useful as a source for the isolation of naturally occurring mutant alleles and are even less useful for the deliberate manipulation of secondary metabolite regulator protein structure with the aim of creating improved regulators of secondary metabolite production.
It would be advantageous to have improved regulators of the biosynthetic enzymes responsible for secondary metabolite production. For example, recent studies suggest increasing usage of statin drugs, e.g., see Waters D. D., Am. J. Cardiol. 88: 10F–5F (2001)). Thus, demand for statin drugs is likely to increase substantially. In order to meet the demand for these and other secondary metabolites, new and improved methods for the production of secondary metabolites must be identified.
BRIEF SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The invention provides variant secondary metabolite regulator proteins that enable production of secondary metabolites. The invention also provides methods to make these variant regulator proteins. Certain of the variant secondary metabolite regulator proteins have increased ability to stimulate production of secondary metabolites in at least some strains of certain fungal species, e.g., certain strains of Aspergillus terreus or Saccharomyces cerevisiae, compared to the cognate wild-type protein.
In certain embodiments of the aspects of the invention, the invention relates to the biosynthesis and improved production of secondary metabolites. The invention provides variant regulator proteins useful for the production of secondary metabolites, nucleic acid molecules encoding variant regulator proteins, and methods for their production.
As used herein, the terms “fungal” and “fungus” refer generally to eukaryotic, heterotrophic organisms with an absorptive mode of nutrition. Fungi typically contain chitin in their cell walls and exhibit mycelial or yeast-like growth habits (More Gene Manipulations in Fungi, edited by J. W. Bennet and L. L. Lasure, Academic Press Inc. (1991), ISBN 0120886421). More specifically, the terms refer to secondary metabolite producing organisms including, without limitation, Aspergillus sp., Penicillium sp., Acremonium chrysogenum, Yarrowia lipolytica, Nodulisporium sp., Fusarium sp., Monascus sp., Claviceps sp., Trichoderma sp., Tolypocladium sp., Tricotheicium sp., Fusidium sp., Emericellopsis sp., Cephalosporium sp., Cochliobolus sp., Helminthosporium sp., Agaricus brunescens, Ustilago maydis, Neurospora sp., Pestalotiopsis sp. and Phaffia rhodozyma (See, Fungal Physiology, Chapter 9 (Secondary(Special) Metabolism), Griffin, D. H., John Wiley & Sons, Inc.; ISBN: 0471166154).
The term “variant regulator protein” is used herein to refer to any regulatory protein having at least one change or difference in the amino acid sequence of the protein when compared to its cognate, wild-type regulatory protein sequence. The term does not include naturally occurring allelic variations of the cognate, wild-type regulatory protein.
The term “regulator protein” is meant to refer to a protein having a positive or negative function that modifies the production of a secondary metabolite. The function of the protein may be at the level of transcription, e.g., repression or activation, protein synthesis, or transport. The regulator may alter the level of transcription, RNA stability, translation, post-translational modification, or cellular localization of proteins involved in secondary metabolite synthesis and/or transport. The regulator may also have effects on precursor metabolite pools, flux through specific pathways and metabolite resistance.
By way of non-limiting example, certain embodiments of the aspects of the invention relate to a regulator protein that is a protein that contributes and/or promotes transcription of a gene sequence, i.e., a transcription-activating protein. “Transcription-activating” is a term used to refer to characteristics of a protein that promote transcription. As used herein, a transcription-activating protein would include proteins that increase accessibility of the DNA to transcription complexes, for example, by opening or relaxing chromatin structure, proteins that promote the recognition and/or binding of transcription complexes to a target gene sequence, and/or proteins that promote transcription complex movement along the length of the template DNA sequence.
Regulatory proteins of secondary metabolite production and the nucleic acid sequences encoding these are known to those skilled in the art. Non-limiting examples of regulatory proteins of secondary metabolite synthesis include: regulator proteins of the aflatoxin/sterigmatocystin biosynthetic cluster (Woloshuk, C. P., et al., Appl, Environ. Microbiol. 60:2408–2414 (1994) and Brown, D. W., et al., Proc Natl Acad Sci USA. 93:1418–1422 (1996)); regulator proteins of the paxilline biosynthetic cluster (Young, C., et al., Mol, Microbiol. 39:754–764 (2001)); regulator proteins of the cephalosporin and penicillin biosynthetic clusters (Litzka O., et al., Antonie Van Leeuwenhoek 75:95–105 (1999); Schmitt E. K. and Kuck U., J. Biol. Chem. 275:9348–9357 (2000); MacCabe et al. Mol. Gen. Genet. 250:367–374 (1996); Suarez et al. Mol. Microbiol. 20:529–540 (1996); Lambert et al. Mol. Cell. Biol. 17:3966–3976 (1997); Su et al. Genetics 133:67–77 (1993); regulator proteins of tricothecene synthesis (Trapp S. C., et al., Mol. Gen. Genet. 257:421–432 (1998); Brown D. W., et al., Fungal Genet. Biol. 32:121–133 (2001); and Matsumoto G., et al. Biosci. Biotechnol. Biochem. 63:2001–2004 (1999)); and regulator proteins of lovastatin synthesis (Kennedy, J., et al., Science 284:1368–1372 (1999); Hendrickson et al., Chem. Biol. 6:429–439 (1999) Tag, A. et al., Mol Microbiol. 38:658–65 (2000)).
Certain embodiments of the aspects of the invention disclosed herein relate to the lovE regulator protein, a protein which plays a key role in the biosynthesis of lovastatin. More particularly, certain embodiments of the aspects of the invention relate to variant proteins of the lovE regulator protein and methods of making the same. Such proteins are variant with respect to the following A. terreus wild-type lovE sequences (SEQ ID NOS:91 and 92).

As used herein, the term “secondary metabolite” means a compound, derived from primary metabolites, that is produced by an organism, is not a primary metabolite, is not ethanol or a fusel alcohol, and is not required for growth under standard conditions. Secondary metabolites are derived from intermediates of many pathways of primary metabolism. These pathways include, without limitation, pathways for biosynthesis of amino acids, the shikimic acid pathway for biosynthesis of aromatic amino acids, the polyketide biosynthetic pathway from acetyl coenzyme A (CoA), the mevalonic acid pathway from acetyl CoA, and pathways for biosynthesis of polysaccharides and peptidopolysaccharides. Collectively, secondary metabolism involves all primary pathways of carbon metabolism. Particularly preferred in embodiments of the aspects of the invention are fungal secondary metabolites (See, Fungal Physiology, Chapter 9 (Secondary(Special) Metabolism), Griffin, D. H., John Wiley & Sons, Inc.; ISBN: 0471166154).
“Secondary metabolite” also includes intermediate compounds in the biosynthetic pathway for a secondary metabolite that are dedicated to the pathway for synthesis of the secondary metabolite. “Dedicated to the pathway for synthesis of the secondary metabolite” means that once the intermediate is synthesized by the cell, the cell will not convert the intermediate to a primary metabolite. “Intermediate compounds” also include secondary metabolite intermediate compounds which can be converted to useful compounds by subsequent chemical conversion or subsequent biotransformation. As such, providing improved availability of such intermediate compounds would still lead to improved production of the ultimate useful compound, which itself may be referred to herein as a secondary metabolite. The yeast Saccharomyces cerevisiae is not known to produce secondary metabolites.
The term “primary metabolite” means a natural product that has an obvious role in the functioning of almost all organisms. Primary metabolites include, without limitation, compounds involved in the biosynthesis of lipids, carbohydrates, proteins, and nucleic acids. The term “increasing the yield of the secondary metabolite” means increasing the quantity of the secondary metabolite present in the total fermentation broth per unit volume of fermentation broth or culture.
As used herein, the phrase “modulate production of a secondary metabolite” refers to a positive or negative or desirable change in one or more of the variables or values that affect the process or results of production of the primary or secondary metabolites in a liquid or solid state fungal fermentation. These positive or negative or desirable changes include, without limitation, an increase or decrease in the amount of a primary or secondary metabolite being produced (in absolute terms or in quantity per unit volume of fermentation broth or per unit mass of solid substrate); a decrease in the volume of the broth or the mass/quantity of substrate required for the production of sufficient quantities; a decrease in the cost of raw materials and energy, the time of fermentor or culture run, or the amount of waste that must be processed after a fermentor run; an increase or decrease in the specific production of the desired metabolite (both in total amounts and as a fraction of all metabolites and side products made by the fungus); an increase or decrease in the percent of the produced secondary metabolite that can be recovered from the fermentation broth or culture; and an increase in the resistance of an organism producing a primary or secondary metabolite to possible deleterious effects of contact with the secondary metabolite.

The phrase “increased activity” is used herein to refer to a characteristic that results in an augmentation of the inherent negative or positive function of the regulatory protein.
The invention provides variant regulator proteins of secondary metabolite production with increased activity and methods of producing the same. The invention further provides for the identification of specific amino acid residues that are important to the functioning of secondary metabolite regulator proteins. By way of non-limiting example, variant regulator proteins of the secondary metabolite regulator lovE are presented herein.
As known to those skilled in the art, certain substitutions of one amino acid for another may be tolerated at one or more amino acid residues of a wild-type regulator protein absent a change in the structure, activity and/or function of the wild-type protein. Such substitutions are referred to in the art as “conservative” substitutions, and amino acids may be categorized into groups that identify which amino acids may be substituted for another without altering the structure and/or function of the protein.
As used herein, the term “conservative substitution” refers to the exchange of one amino acid for another in the same conservative substitution grouping in a protein sequence. Conservative amino acid substitutions are known in the art and are generally based on the relative similarity of the amino acid side-chain substituents, for example, their hydrophobicity, hydrophilicity, charge, size, and the like. In a preferred embodiment, conservative substitutions typically include substitutions within the following groups: Group 1: glycine, alanine, and proline; Group 2: valine, isoleucine, leucine, and methionine; Group 3: aspartic acid, glutamic acid, asparagine, glutamine; Group 4: serine, threonine, and cysteine; Group 5: lysine, arginine, and histidine; Group 6: phenylalanine, tyrosine, and tryptophan. Each group provides a listing of amino acids that may be substituted in a protein sequence for any one of the other amino acids in that particular group.
As stated supra, there are several criteria used to establish groupings of amino acids for conservative substitution. For example, the importance of the hydropathic amino acid index in conferring interactive biological function on a protein is generally understood in the art (Kyte and Doolittle, Mol. Biol. 157:105–132 (1982). It is known that certain amino acids may be substituted for other amino acids having a similar hydropathic index or score and still retain a similar biological activity. Amino acid hydrophilicity is also used as a criteria for the establishment of conservative amino acid groupings (see, e.g., U.S. Pat. No. 4,554,101).
Information relating to the substitution of one amino acid for another is generally known in the art (see, e.g., Introduction to Protein Architecture: The Structural Biology of Proteins, Lesk, A. M., Oxford University Press; ISBN: 0198504748; Introduction to Protein Structure, Branden, C.-I., Tooze, J., Karolinska Institute, Stockholm, Sweden (Jan. 15, 1999); and Protein Structure Prediction: Methods and Protocols (Methods in Molecular Biology), Webster, D. M. (Editor), August 2000, Humana Press, ISBN: 0896036375).
In one embodiment of the first aspect, the invention provides an improved regulator protein comprising an amino acid sequence coding for a variant of the lovE protein having at least one specific mutation that gives rise to greater transcription-activating properties of the regulator protein and/or increased lovastatin synthesis.
By way of non-limiting example, certain amino acid residues and mutations thereof in the lovE regulatory protein of A. terreus (SEQ ID NO:91) are identified by the invention described herein. Mutations at residues 31, 41, 52, 73, 101, 111, 133, 141, 153, 281, 367, and 389 of the wild-type lovE protein of A. terreus have been identified as being critical for the improvement of lovE regulator protein function. Those mutations include: F31L, Q41K, Q41R, T52I, T52N, C73R, P101S, P101Q, V111I, S133L, E141V, E141K, C153Y, C153R, T281A, N367I, N367Y, P389S and P389L. Each mutation, therefore, represents a change of one conservative class of amino acids for another. For example, the mutation F31L represents a change from a Group 6 amino acid residue to a Group 2 amino acid residue at position 31 of the wild-type, lovE regulator protein. Other mutations include the mutations described herein, e.g., V17L, H39L, A40T, R76H, H96R, S112P, T119I, P183L, S186R, A204T, the deletion of amino acids 271–373, I283L, L288Q, M299I, E303V, R312K, D314E, the deletion of S316, S317, S318, or S319, T396K, M418L, S421T, L461F, and I467N.
Poor transformation efficiency and the lack of efficient selection systems frequently preclude the screening of large numbers of variant regulator proteins of secondary metabolites in the organism from which the regulator protein is isolated. For example, there are currently certain technical obstacles to the successful screening of large numbers of variant regulator proteins in the fungus A. terreus, an organism that produces the secondary metabolite lovastatin.
The invention described herein takes advantage of the genetically tractable and experimentally amenable organism (e.g., Saccharomyces cerevisiae and other fungal organisms) for screening large numbers of variant regulator proteins of secondary metabolite production. Techniques common to the field of molecular biology are well developed in S. cerevisiae, and large numbers of vectors are available to assist the genetic manipulation and cloning of variant regulator proteins involved in secondary metabolite production. Other genetically tractable organisms could also be used for this purpose.
As used herein, “mutating” is used to refer to the deliberate alteration of at least one nucleotide residue of a wild-type, cognate nucleic acid sequence encoding a regulator protein of secondary metabolite production. A deliberate alteration or change in at least one nucleotide residue of a polynucleotide may be accomplished by any method known in the art. The mutation(s) can be made in vivo or in vitro and can include random, partially random or not random, i.e., directed, mutagenesis techniques.
By way of non-limiting example, in vivo mutagenesis can be done by placing this nucleic acid molecule in a cell with a high mutation frequency, i.e. a mutagenic strain. By way of non-limiting example, Muhlrad et al. (Yeast 8:79–82 (1992)) have developed a rapid method for localized mutagenesis of yeast genes. As a first step, the region of interest of a gene sequence is first amplified in vitro under error-prone polymerase chain reaction (PCR) conditions. Error-prone polymerase chain reaction (PCR) is a method of introducing amino acid changes into proteins. With this technique, mutations are deliberately introduced during the PCR reaction through the use of error-prone DNA polymerases under specific reaction conditions. With the Muhlrad et al. procedure, the PCR product is then co-transformed with a gapped plasmid containing homology to both ends of the PCR product, resulting in in vivo recombination to repair the gap with the mutagenized DNA.
There are a variety of commercially available kits that may be used to produce mutant nucleic acid molecules by error-prone PCR (see, e.g., GeneMorphTM PCR Mutagenesis Kit (Stratagene, La Jolla, Calif.); and DiversifyTM PCR Random Mutagenesis Kit (BD Biosciences Clontech, Palo Alto, Calif.). Thus, a plurality of variant, i.e., mutated, regulator proteins of secondary metabolite production may be produced using established mutagenesis techniques.
As used herein, the term “activity” refers to a characteristic of the regulator protein that negatively or positively affects the biological system to bring about a modulation in secondary metabolite production. By way of non-limiting example, the activity is the transcription of downstream genes involved in the biosynthetic pathway of the secondary metabolite of choice. Thus, in the present example, the phrase “more activity” refers to the property of a variant regulator protein to bring about more transcription than that effected by the cognate, wild-type regulator protein.
In certain embodiments of the third aspect, the selected variant regulator protein has more activity in a fungal cell than the cognate, wild-type protein. In certain embodiments of the third aspect, the protein regulator of secondary metabolite production is a transcription factor. In certain embodiments of the fourth aspect, the protein regulator of secondary metabolite production is a transmembrane transporter, a protein that mediates secretion, a kinase, a G-protein, a cell surface receptor, a GTPase activating protein, a guanine nucleotide exchange factor, a phosphatase, a protease, a phosphodiesterase, a bacterial protein toxin, an importin, an RNA-binding protein, an SCF complex component, an adherin, or a protein encoded within a biosynthetic cluster. In certain other embodiments of the third aspect, the selected variant regulator protein has more activity in a heterologous cell than the cognate, wild-type protein. In certain embodiments thereof, the heterologous cell is an organism selected from the group consisting of S. cerevisiae, E. coli, A. nidulans, Candida sp., and N. crassa.

In certain embodiments of the third aspect, the selected variant regulator protein has more activity in a heterologous cell and a homologous cell than the cognate, wild-type protein. In certain embodiments thereof, the heterologous cell is an organism selected from the group consisting of S. cerevisiae, E. coli, A. nidulans, Candida sp., and N. crassa and the homologous cell is an organism selected from the group consisting of Aspergillus sp., Penicillium sp., Acremonium chrysogenum, Yarrowia lipolytica, Nodulisporium sp., Fusarium sp., Monascus sp., Claviceps sp., Trichoderma sp., Tolypocladium sp., Tricotheicium sp., Fusidium sp., Emericellopsis sp., Cephalosporium sp., Cochliobolus sp., Helminthosporium sp., Agaricus brunescens, Ustilago maydis, Neurospora sp., Pestalotiopsis sp. and Phaffia rhodozyma. 
As used herein, the phrase “heterologous cell” refers to a system for gene expression, i.e., an organism for gene expression, that is one other than the organism from which the selected regulator protein of secondary metabolite production has been isolated. Preferred heterologous cells include, but are not limited to, S. cerevisiae, E. coli, A. nidulans, and Candida sp., and N. crassa. Particularly preferred are fungal heterologous cells. In an embodiment of the third aspect, the method comprises: (a) selecting a nucleic acid comprising a polynucleotide encoding a protein regulator of secondary metabolite production; (b) mutating the nucleic acid to create a plurality of nucleic acid molecules encoding variant regulator proteins of secondary metabolite production; and (c) selecting a mutagenized nucleic acid encoding a variant regulator protein with increased activity in a homologous cell than the cognate, wild-type protein.
As used herein, the phrase “homologous cell” refers to a system for gene expression, i.e., an organism for gene expression, that is the organism from which the regulator protein of secondary metabolite production has been isolated. Preferred homologous cells are fungal homologous cells, including, but not limited to, Aspergillus sp., Penicillium sp., Acremonium chrysogenum, Yarrowia lipolytica, Nodulisporium sp., Fusarium sp., Monascus sp., Claviceps sp., Trichoderma sp., Tolypocladium sp., Tricotheicium sp., Fusidium sp., Emericellopsis sp., Cephalosporium sp., Cochliobolus sp., Helminthosporium sp., Agaricus brunescens, Ustilago maydis, Neurospora sp., Pestalotiopsis sp and Phaffia rhodozyma. (See, Fungal Physiology, Chapter 9 (Secondary(Special) Metabolism), Griffin, D. H., John Wiley & Sons, Inc.; ISBN: 0471166154).
In certain embodiments of the third aspect, the method further comprises selecting a variant regulator protein that also increases production of a secondary metabolite in a cell when compared to the cognate, wild-type protein. In certain embodiments thereof, the cell is a fungal cell. In certain embodiments thereof, the cell is a heterologous cell, preferably selected from the group consisting of S. cerevisiae, E. coli, A. nidulans, Candida sp., and N. crassa. 
In certain embodiments thereof, the cell is a homologous cell, preferably selected from the group consisting of Aspergillus sp., Penicillium sp., Acremonium chrysogenum, Yarrowia lipolytica, Nodulisporium sp., Fusarium sp., Monascus sp., Claviceps sp., Trichoderma sp., Tolypocladium sp., Tricotheicium sp., Fusidium sp., Emericellopsis sp., Cephalosporium sp., Cochliobolus sp., Helminthosporium sp., Agaricus brunescens, Ustilago maydis, Neurospora sp., Pestalotiopsis sp., and Phaffia rhodozyma. 
Certain embodiments of the aspects of the invention relate to regulator proteins that promote secondary metabolite production by increasing transcription of one or more genes involved with secondary metabolite production. These wild-type sequences may be selected for mutagenesis to create a plurality of variant regulator proteins. The activity of these transcription-activating variant regulator proteins may be determined by measuring the activity of a reporter gene having the appropriate promoter sequences. These tests are done in a homologous and/or a heterologous cell. Certain embodiments of aspects of the invention are directed to fungal regulator proteins with transcription-activating activity that is tested in fungal heterologous and homologous cells.
Reporter genes are useful for isolating transformants expressing improved variant regulator proteins. The reporter genes may be operably linked to a promoter sequence that is normally regulated by the wild-type regulator protein. Reporter genes include, but are not limited to, genes encoding β-galactosidase (lacZ), β-glucoronidase (GUS), β-glucosidase, amylase and invertase, amino acid biosynthetic genes, e.g., the yeast LEU2, HIS3, LYS2, TRP1 genes (or homologous genes from other fungi, such as filamentous fungi, that encode proteins with the similar functional activities), nucleic acid biosynthetic genes, e.g., the yeast URA3 and ADE2 genes (or homologous genes from other fungi, such as filamentous fungi, that encode proteins with the similar functional activities), the mammalian chloramphenicol transacetylase (CAT) gene, or any surface antigen gene for which specific antibodies are available. A reporter gene can also be a neomycin phosphotransferase(neo) gene, which encodes neomycin, kanamycin resistance gene, a ble gene, which encodes phleomycin resistance, or a G418 (geneticin) resistance gene. A reporter gene may encode a protein detectable by luminescence or fluorescence, such as green fluorescent protein (GFP). Reporter genes may additionally or alternatively encode any protein that provides a phenotypic marker, for example, a protein that is necessary for cell growth or viability, or a toxic protein that causes cell death. Alternatively, the reporter gene may encode a protein detectable by a color assay leading to the presence or absence of color.
The choice of reporter gene will depend on the type of cell to be transformed. Preferred reporter genes are those that are operable in fungal cells. It is preferable to have two reporter genes within the cell. One reporter gene, when expressed, provides a growth advantage to transformed cells that are expressing the variant regulator protein. This allows for the isolation of such transformants though selective pressures. The other reporter gene provides a colorimetric marker, such as the lacZ gene and its encoded protein, β-galactosidase. Alternatively, the second reporter provides a fluorescent or luminescent marker, such as green fluorescent protein (GFP).

Preparation of Strains and Plasmids
Strain MY2124 was derived from the Sigma 1278b strain background of S. cerevisiae and its complete genotype is as follows: MATα/MATα:LEU2 ura3Δ0/ura3α0 leu2Δ0/leu2Δ0 trp1Δ0::hisG/trp1Δ0::hisG his3Δ0::hisG/his3Δ0::hisG ura3Δ0::lovF-HIS3p-neo/ura3Δ0. MY2124 can be constructed by mating S. cerevisiae strains MY2112 (MATα ura3Δ0 leu2Δ0 trp1Δ0::hisG his3Δ0::hisG ura3Δ0::lovFp-HIS3p-neo) with MY1555 (matα::LEU2 ura3Δ0 leu2Δ0 trp1Δ0::hisG his3Δ0::hisG) and isolating zygotes. The ura3Δ0::lovFp-HIS3p-neo allele of MY2112 was derived by cotransforming SfiI-linearized plasmid MB2254 with pRS424 (Sikorski and Hieter (1989) Genetics 122:19–27) into MY1413 (MATα leu2Δ0 trp1Δ0::hisG his3Δ0::hisG). Transformants were selected on SC-Trp media and subsequently screened for 5-fluoro-orotic acid resistance to identify those transformants containing the ura3Δ0::lovFp-HIS3p-neo allele. Trp− segregants lacking plasmid pRS424 were isolated by growing the strain under non-selective conditions.
The following oligonucleotides were used in the construction of plasmids.

Plasmid MB2254 contains the lovFp-HIS3p-neo reporter gene flanked by URA3 sequence. First primers MO664 (SEQ ID NO:1) and MO665 (SEQ ID NO:2) were annealed and inserted into the KpnI-SacI sites of plasmid pBluescript II KS (Stratagene,). The resulting vector, MB1038, contains a SalI site in the polylinker. Next, the SpeI-XhoI fragment from pJL164 (Brachmann et al. Yeast 14:115–132 (1998)) containing a deletion of the URA3 gene with additional flanking sequences was inserted into the NheI-SalI sites of MB1038 to create MB1053. Primers MO666 (SEQ ID NO:3) and MO667 (SEQ ID NO:4) that contain multiple restriction sites (NotI, XbaI, SpeI, XhoI and KpnI) were then annealed together and ligated into the SmaI site of MB1053 to create MB1054. Next, the following four fragments were combined in MB1054 to obtain plasmid MB2254. The lovF promoter from A. terreus genomic DNA was PCR amplified with MO1794 (SEQ ID NO:5) and MO1793 (SEQ ID NO:6) and inserted into MB1054 on a NotI-SpeI fragment. The HIS3 basal promoter from pRS403 (Sikorski and Hieter, Genetics 122:19–27 (1989)) was PCR amplified with primers MO1785 (SEQ ID NO:7) and MO1786 (SEQ ID NO:8) and inserted into MB1054 on a SpeI-BamHI fragment. Finally, the neo gene (PCR amplified with MO195 (BamHI) (SEQ ID NO:) and MO196 (EcoRI) (SEQ ID NO:10) from plasmid pYX11 (Xiao and Weaver, Nucl. Acids Res. 25:2985–2991 (1997)) and CYC1 terminator sequences (XhoI-KpnI fragment from pRS426-GAL-S (Mumberg, et al., Nucl. Acids. Res. 22:5767–5768 (1994)) were first combined in pRS416 (Sikorski and Hieter, Genetics 122:19–27 (1989)) and then cut out with BamHI-KpnI and inserted into MB1054 to create MB2254.
The lovFp-HIS3p-neo reporter in MY2124 can confer resistance to the drug geneticin (G418). It was empirically determined that MY2124 (untransformed or transformed with parental plasmids MB2478 (CYC1-lovE/CEN) or MB2848 (CYC1-lovE/At274/CEN) was unable to grow on YPD media supplemented with 100 μg/ml G418. Plasmid MB2478 contains the CYC1 promoter operationally linked to the entire A. terreus lovE open reading frame. The CYC1 promoter is a relatively weak promoter and thus the lovE ORF in MB2478 was expressed at low levels. MB2478 was the parental vector plasmid for creating full length lovE variants. Plasmid MB2848 contains the CYC1 promoter operationally linked to a chimeric open reading frame consisting of the A. terreus lovE DNA binding domain fused to the carboxy-terminal portion of the At274 gene (U.S. Ser. No. 60/257,431, filed Dec. 22, 2000).
MB2848 was used to create lovE variants in which the DNA binding domain was not mutated. Both MB2478 and MB2848 contain yeast CEN and autonomously replicating sequences and both are maintained at 1–2 copies per cell. In contrast to strains transformed with MB2478 or MB2848, strains transformed with plasmid MB1644 (TEF1-lovE/2 micron) were able to grow on G418-supplemented YPD media. The lovE gene of MB1644 is under control of the constitutively strong S. cerevisiae TEF1 promoter. MB1644 contains a 2-micron origin for high-copy replication in yeast. An objective of these studies was to identify lovE variants which when expressed at low levels could confer G418 resistance similar to the highly expressed wild-type lovE molecule of MB1644. S. cerevisiae expression vectors used in these studies were constructed as follows.
MB968 is a low copy S. cerevisiae URA3 based expression vector. MB968 was created by inserting the EcoRV fragment (containing the destination cassette) from gateway pEZC7201 (InvitrogenTM, Carlsbad, Calif.) into XhoI/SalI (filled in with Klenow) linearized pRS416 CYC1 (Mumberg, et al., Gene 156:119–122 (1995)).
MB1644 and MB2478 are URA3-based S. cerevisiae expression plasmids that contain the wild-type lovE gene. They are both derivatives of MB1199. MB1199 was created by using primers MO841 (SEQ ID NO:11) and MO842 (SEQ ID NO:12) to amplify the lovE ORF from A. terreus cDNA. Gateway (InvitrogenTM, Carlsbad, Calif.) Cloning Technology (U.S. Pat. No. 5,888,732) was used to clone the lovE PCR fragment into the gateway entry vector pDONR206 (InvitrogenTM, Carlsbad, Calif.) to create MB1199. Similarly, Gateway Cloning Technology was used to transfer the lovE ORF from MB1199 into MB968 to create MB2478 and into MB969 (U.S. Ser. No. 60/198,335, filed Apr. 18, 2000) to create MB1644.
MB2848 is a derivative of MB968 that contains a lovE-AT274 chimera. The lovE portion of MB2848 was derived by using oligos MO841 (SEQ ID NO:11) and MO2278 (SEQ ID NO:13) to PCR amplify the lovE DNA binding domain from A. terreus cDNA. A second round of PCR was performed with primers MO343 (SEQ ID NO:14) and MO2278 to add appropriate Gateway Cloning Technology compatible sequences. The At274 portion of MB2848 can be derived by using primers MO2273 (SEQ ID NO:15) and MO2274 (SEQ ID NO:16) to PCR amplify the carboxy-terminal domain of At274 from A. terreus cDNA. A second round of PCR was performed with primers MO344 (SEQ ID NO:17) and MO2273 to add appropriate Gateway Cloning Technology compatible sequences. The lovE and At274 PCR products were cut with BamHI and purified over a QIAquick PCR purification kit (Qiagen, Valencia, Calif.) according to manufacturer's instructions. Finally, the products were mixed 3–4 hours in a standard ligation reaction and used in Gateway entry and destination reactions to create MB2848.
Gateway cloning technology was used to clone the lovE variants of interest into plasmid MB1419 which is a filamentous fungal expression vector. The MB1419 fungal selection marker is the A. nidulans GPD promoter controlling the ble gene from S. hindustanus. The transgene is controlled by the A. nidulans PGK promoter. A. terreus strain MF117 is a derivative of A. terreus strain ATCC 20542.
Example 2
PCR Mutagenesis of the lovE DNA Binding Domain
The zinc finger DNA binding domain of lovE is encoded by nucleotides 100–201 (SEQ ID NO:92). Oligos MO2624 (SEQ ID NO:18) and MO2654 (SEQ ID NO:19) were used to PCR amplify a lovE containing fragment from plasmid MB2478. The 1.7 kb product contains nucleotides 212–1410 of lovE and  ̃500 bp of flanking vector sequence. Two rounds of standard PCR (1.5 mM MgCl2) were performed with Amplitaq DNA polymerase (Applied Biosystems, Foster City, Calif.) according to the manufacturer's instructions.
Plasmid MB2848 was cut with KpnI-BamHI to release a 1.1 kb fragment containing the At274 portion of the lovE-At274 chimeric open reading frame. The remaining 5.5 kb vector sequence retains the lovE DNA binding domain.
Example 3
PCR Mutagenesis of the lovE Open Reading Frame
lovE open reading frame insert was prepared according to the following procedure. Oligo pairs MO2680 (SEQ ID NO:20)/MO2686 (SEQ ID NO:21), MO2681 (SEQ ID NO:22)/MO2686, and MO2700 (SEQ ID NO:23)/MO2701 (SEQ ID NO:24) were used to PCR amplify the entire lovE open reading frame from plasmid MB2478. The PCR products differ in the amount of 5′ and 3′ vector sequence flanking the lovE open reading frame.
PCR was performed using a GeneMorph PCR mutagenesis kit (Stratagene, La Jolla, Calif.) according to manufacturer's instructions to achieve medium and high range mutation frequencies.
Plasmid MB2478 was cut with Asp718/XbaI to release a 1.7 kb fragment. The remaining 5.0 kb vector sequence completely lacks lovE ORF sequence.
Example 4
Transformation and Selection for G418R Isolates
All PCR products were purified using a QIAquick PCR purification kit (Qiagen) according to manufacturer's instructions. All vectors were gel purified using a QIAquick gel extraction kit (Qiagen) according to manufacturer's instructions.
The mutagenesis strategy of Muhlrad et al. (Yeast 8:79–82 (1992)) was used which involves cotransforming a mutated PCR product and gapped plasmids into S. cerevisiae, and then screening for in vivo recombinants having the desired phenotype).
Transformation of Saccharomyces cerevisiae was accomplished by the lithium acetate/single-stranded carrier DNA/polyethylene glycol (LiAc/ss-DNA/PEG) protocol (Woods R. A. and Gietz R. D. Methods Mol. Biol. 177:85–97 (2001)) with a 1:5 molar ratio of vector:insert DNA to generate >55,000 in vivo recombinant transformants on SC-Ura plates. Transformants were transferred by replica printing to YPD plates containing 100 μg/ml G418 and allowed to grow for 2–4 days at 30° C. (FIG. 1).
Drug resistant clones were confirmed in secondary assays including growth on G418 concentrations up to 2000 μg/ml. The plasmid-dependence of the phenotype was determined by observing the re-appearance of drug sensitivity correlating with loss of the library plasmid. lovE variant plasmids were recovered from promising candidates (Hoffman and Winston (1986) Gene 57:267). More than 70 lovE variants were identified and definitively characterized by DNA sequence and/or restriction digestion analysis.
Table 3 summarizes the G418 resistance phenotype and sequence analysis of 26 of these variants.

Increased lovF-lacZ Expression in S. cerevisiae 
In order to quantify the increase in lovF expression, β-galactosidase activity was measured in lovE variant transformed S. cerevisiae strains that also harbored lovFp-lacZ reporter derivative plasmids. lovF-lacZ reporter derivative plasmids were constructed as follows.
Plasmid MB1918 contains the lovFp-lacZ reporter gene. It can be derived from pRS424 (Sikorski and Hieter (1989) Genetics 122:19–27). First, primers MO107 (SEQ ID NO:25) and MO197 (SEQ ID NO:26) are used to PCR amplify the lacZ gene from Yep355 (Myers, et al., Gene 45:299–310 (1986)). This lacZ-containing fragment was inserted into the BamHI-HindIII sites of pRS416 (Sikorski and Hieter, Genetics 122:19–27 (1989)). This same lacZ fragment can be cut out of the resulting vector with KpnI-NotI and inserted into the same sites of pRS424 to create pRS424-lacZ. Primers MO1293 (SEQ ID NO:27) and MO1294 (SEQ ID NO:28) are used to PCR amplify a 2.09 kb fragment of the lovF promoter from A. terreus genomic DNA. The lovF promoter fragment was then cut with NotI-BglII and inserted into NotI-BamHI linearized pRS424-lacZ.
Plasmid MB2114 contains the lovFp-CYC1p-lacZ reporter gene. It can be derived from pRS424-lacZ (see MB1918 plasmid construction). Primers MO1787 (SEQ ID NO:29) and MO1788 (SEQ ID NO:30) are used to amplify the 264 bp basal CYC1 element from pRS415 CYC1 (Mumberg, et al., Gene 156:119–122 (1995)). This 264 bp fragment was inserted upstream of the pRS424-lacZ derivative which has been digested with SpeI-BamHI. Finally, the lovF promoter from MB1918 was PCR amplified with MO1793 (SEQ ID NO:31) and MO1794 (SEQ ID NO:32) and inserted into the NotI-SpeI sites to create MB2114.
Yeast strains utilized in this study include strains MY2145 and MY2159, which are both derived from the S. cerevisiae sigma 1278b strain background; the genotypes are both strains are as follows: MATa ura3Δ0 leu2Δ0 his3Δ::hisG trp1Δ0::hisG. MY2145 and MY2159 contain the lovFp-lacZ reporter plasmids MB2114 and MB1918, respectively.
MY2124 transformed with individual lovE variant plasmids was mated to S. cerevisiae strains MY2154 and MY2159. Diploids were selected on SC-UraTrp media. Multiple diploids from each individual mating were assayed for lovFp-lacZ expression using 96 well format β-galactosidase assays. For β-galactosidase assays, cells were transferred from transformation plates to 96-well microtiter plates containing 200 μl Z buffer. 12 strains were transferred simultaneously using a 12-channel multi-pipettor to scoop cells from transformation plates. Duplicate samples were prepared for all assays. OD600 readings were taken on samples in Z buffer. These values were used to normalize for equal cell number in all assays. After determining OD600, 150 μl of each sample in Z buffer was transferred onto a Millipore Multiscreen Assay System (Nitrocellulose Immobilon NC), filtered, and then washed by filtering 200 μl Z buffer. 100 μl Z buffer with βME and detergents was then added to each well, as was 20 μl 4 mg/ml ONPG. Reactions were incubated at 30° C., stopped with 50 μl 1 M Na2CO3, filtered into a polystyrene 96-well assay plate, and OD420 was determined for each assay well. β-galactosidase units were determined using the Miller formula (O.D. 420×1000)/(OD600*minutes*volume in mL). Z buffer is made by dissolving the following in 1 L of water (16.1 g Na2HPO4-7H2O, 5.5 g NaH2PO4—H2O, 0.75 g KCl and 0.246 g MgSO4-7H2O). Z buffer with detergents and βME is made as follows: 9.8 ml Z buffer, 100 μl 20 mg/ml CTAB, 100 μl 10 mg/ml sodium deoxycholate, and 69 μl βME. Control plasmids utilized in these studies included MB968, MB2478 and MB1644.
Results of these studies are presented in FIGS. 2–5, demonstrating increased transcription-activating properties of the lovE variants disclosed herein.
Example 6
Secondary Metabolite Production
Transformation of filamentous fungi was performed according to the following procedure. Protoplasts were generated by inoculating rich media with spores. Spores were allowed to germinate for about 20 hrs or until germ tubes were between 5 and 10 spore lengths. The germlings were centrifuged and washed twice with sterile distilled water and once with 1 M magnesium sulfate. Germlings were then resuspended in 1M magnesium sulfate containing approximately 2 mg/ml of Novozyme. Tubes were then incubated at 30° C. shaking at 80 RPM for about 2 hrs or until most of the hyphae were digested and protoplasts were abundant. Protoplasts were filtered through one layer of Miracloth. At least one volume of STC was added and protoplasts were centrifuged. Protoplasts were washed twice with STC. Protoplasts then were resuspended in 1 ml STC and counted in a hemacytometer. A final concentration of approximately 5×107 protoplasts/ml were frozen in a 9:1:0.1 solution of STC, SPTC and DMSO in a Nalgene Cryo cooler at −80° C. (cools −1° C./min).
Solutions for transformation were as follows: STC (0.8 M Sorbitol, 25 mM Tris-HCl pH 7.5, 25 mM CaCl2) and SPTC (0.8 M Sorbitol, 40% PEG 4000, 25 mM Tris-HCl pH 8, 50 mM CaCl2). Transformation was accomplished according to the following protocol. 1–5 μg of DNA comprising a lovE variant according to the invention in a fungal expression vector was placed in a 50 ml Falcon tube. 100 μl of previously frozen protoplasts were added to the DNA, gently mixed, and then incubated on ice for 30 min. 15 μl of SPTC was added, followed by mixing by tapping and incubation at RT for 15 min. 500 μl SPTC was added and mixed well by tapping and rolling, then incubated at RT for 15 min. 25 mls of regeneration minimal medium was added, mixed well and poured on plates containing 25 mls of regeneration minimal medium with 2× the concentration of selection drug.
Transformation plates were incubated at 26° C. for 5–6 days or until colonies started to appear. Regeneration minimal medium contains trace elements, salts, 25 mM sodium nitrate, 0.8 M Sucrose, and 1% agarose at pH 6.5. The selection drug that was used successfully with A. terreus is phleomycin, a broad-spectrum glycopeptide antibiotic. Transformants were picked onto new plates with a toothpick (if the fungus was sporulating) or with sterile forceps (if the fungus did not sporulate). Purification plates contained minimal medium (same as regeneration minimal medium but containing 2% instead of 0.8 M sucrose) and 1× drug concentration. Picked transformants were incubated at 26° C. for 5–6 days.
Transformants were grown in production media for secondary metabolite production. Briefly, for A. terreus and lovastatin production, spores were used as the inoculum. Spores were obtained from the purification plate by using a wooden inoculation stick. The medium was RPM containing corn steep liquor, sodium nitrate, potassium phosphate, magnesium sulfate, sodium chloride, P2000 (Dow chemical), trace elements and lactose or glucose as carbon source. The medium was pH 6.5. Flasks were incubated at 26° C. with shaking at 225 RPM. For static 96-well cultures, the same medium was used and the spores were obtained from the purification plate with a wooden toothpick. 96-well plates were incubated, without shaking at 26° C.
Sampling was done after 5 days for lovastatin. For shake flask experiments 1–1.5 mls of supernatant was placed into 96-well plates, which were centrifuged and supernatants transferred to new 96-well plates. Samples were frozen at −80° C. for storage or for later assays.
Cultures that were grown standing in a 96-well plate were centrifuged and the supernatant was transferred to a new 96 well plate. Samples were frozen at −80° C.
Example 7
Measurement of Secondary Metabolite Production
The concentration of the secondary metabolite lovastatin was determined by enzyme inhibition assay (FIG. 6). Briefly, 10 μL of sample was removed and diluted 1:100 in H2O. 10 μl of this diluted broth was assayed in a reaction (200 μL total) containing 1 mM HMGCoA, 1 mM NADPH, 0.005 mM DTT and 5 μl (His)6HMGR. The disappearance of absorbance at 340 nm was observed over time. This represents the disappearance of NADPH, and lovastatin inhibits this reaction.
The initial velocities were calculated for the reactions containing samples, adjusted for dilution, and compared to reactions containing lovastatin standards to determine levels of metabolite produced. (His)6HMGR was expressed in Saccharomyces cerevisiae and purified with a nickel column.
The results from ten individual transformants for each allele are shown in standard box plot format in FIG. 6. Lovastatin concentration from the corresponding wild-type lovE control is shown in matching fill pattern. For example, lovE alleles 2, 7, 8 and 9 were all transformed and assayed at the same time as the non-hatched wild-type control. The horizontal line in each individual box represents the median.
Lovastatin concentration was also determined by high pressure liquid chromatography (HPLC). Briefly, 100 μL of broth sample was removed and diluted 1:10 into 70% H2O-30% acetonitrile (900 μl). This mixture was spun down to pellet debris at 13000 RPM for 5 minutes. 900 μl of this diluted broth was transferred to a vial and the sample was analyzed by HPLC. 10 μl were injected into a Waters HPLC system (996 photo-diode array detector, 600 E pump controller and 717 autosampler) equipped with a YMC-Pack ODS column (Aq-302-3, 150×4.6 mm ID, S-3 μM pore size) and eluted with isocratic 40% aqueous acetic acid (0.7%)-60% acetonitrile for 8 minutes. Lovastatin was detected at 238 nm to have a retention time of 6.5 minutes and was quantified using a calibration curve created from pure lovastatin samples.
The results from ten individual transformants for each lovE variant are shown in standard box plot format in FIGS. 7A and 7B. Thirty individual wild-type lovE transformants and ten individual MB2143 negative control transformants were tested. Identical controls are plotted in FIGS. 7A and 7B.
PCR analysis of A. terreus transformants demonstrates that greater than fifty percent of the transformants contain the transgene. Variability in levels of transgene expression can presumably be influenced by integration site and copy number. lovE variants containing identical amino acid substitutions are labeled.
The amino acid and nucleic acid sequences of lovE variant sequences are presented in Table 5 and Table 6, respectively.
Example 8
Isolation of Additional Forms of lovE
An A. terreus cDNA was screened to identify sequences that increase expression of a lovF reporter gene in A. terreus. This analysis led to the identification of two cDNAs that could encode lovE variants having additional amino acids at their amino terminus compared to the love of SEQ ID NO:91. One variant, at242, has the amino sequence mtqdtaqyrga (SEQ ID NO:95) preceding the sequence of SEQ ID NO:91. The entire amino acid sequence of at242 (SEQ ID NO:93) is shown in Table 7. The other variant, at258, has the amino sequence mlmtqdtaqyrga (SEQ ID NO:96) preceding the sequence of SEQ ID NO:91. The entire amino acid sequence of at258 (SEQ ID NO:94) is shown in Table 7. Thus, both variants appear to encode forms of lovE that is longer than the lovE of SEQ ID NO:91. The various amino acid changes present in the various love variants of Table 5 can be introduced into the at242 or at258 to generate additional forms of lovE.
Example 9
Generation of Additional lovE Variants
New lovE variants were generated using plasmid MB3048 as a template for mutagenic PCR. MB3048 is a gateway entry plasmid which encodes the at242 form of lovE. The Gene Morph® PCR kit (Stratagene) was used with oligos MO985 (5′TTACCGCTAGCATGGATCTCG3′) (SEQ ID NO:115) and MO986 (5′TCTTGTGCAATGTAACATCAG3′) (SEQ ID NO:116) to generate PCR products containing mutations in the lovE coding sequence. Gateway Cloning Technology® was used to generate an E. coli library of mutants in plasmid MB3647. The lovE coding sequences in the MB3647 plasmid are operably linked to the A. nidulans PGK promoter. DNA was isolated from the libraries using a Qiagen Maxi® kit and transformed into fungal reporter strains MF186 and MF191. These strains contain the lovF promoter fused to the ble gene which confers resistance to phleomycin (Drocourt et al. Nucl. Acids Res. 18:4009, 1990). These strains also contain an endogenous copy of wild type lovE which activates the lovF promoter, and thus are able to grow at phleomycin concentrations of 10 μg/ml or less. Transformants expressing a functional lovE variant should be capable of growing at phleomycin concentrations above 10 μg/ml. Transformants which grew at elevated phleomycin concentrations (concentrations of 75, 150, 300, and 600 μg/ml) were picked to 12 well plates of identical phleomycin concentration, or to minimal plates, grown for 5 days and analyzed for lovastatin production.
Genomic DNA was prepared from selected transformants exhibiting increased phleomycin resistance and PCR-amplified using Pfu polymerase and oligos MO3100 (GAGCTGTATCTGGAAGAGG) (SEQ ID NO:117) and MO3452 (CGTCCATCTCTCTCCGTA) (SEQ ID NO:118), in order to amplify the transfected lovE sequences without amplifying the native, wild type lovE gene. PCR products were introduced into GatewayTM Entry vectors (Invitrogen) via a “BP” reaction and sequenced by established protocols (Seqwright, Inc.). Three clones were identified which contained one PGK-lovE variant (lovE 198, lovE 22409, and lovE 32403A4). In addition, three clones were identified which contained two different PGK-lovE variants in the original isolate (lovE 199-1 and lovE 199-2; lovE 32691A2-1 and lovE 32691A2-2; and lovE 32701C1-1 and lovE 32701C1-2). The amino acid and nucleotide sequences of these variants are shown in Table 5 and Table 6, respectively. The amino acid changes present in each clone are shown in Table 8, below.
The lovE variants were cloned into a Gateway vector and re-transformed into a parental strain of the fungal strain used for selection. Levels of lovastatin production in transformants expressing lovE variants are depicted in FIGS. 8 and 9. Briefly, transformants were cultured and lovastatin levels were assayed by HPLC as described in Example 7, above. FIG. 8 shows lovastatin levels produced by MF172 harboring a vector expressing various lovE variants. Transformants containing empty vector (MB2153) (n=24) produced between 1.5 and 2.4 g/l of lovastatin, with an average production of approximately 2 g/l. Transformants containing the At242 lovE isoform (n=48) produced between 1.8 and 3 g/l of lovastatin, with an average production of approximately 2.5 g/l. Transformants expressing lovE variant AT32403A4 (n=48) produced between 0.8 and 3.4 g/l of lovastatin, with an average of approximately 2.78 g/l. (numbers were changed based on looking at the original data, the scale is every 0.5 not every 1) Transformants expressing the lovE variant 198 (n=24) produced between 1.8 and 3.36 g/l of lovastatin, with an average of approximately 2.6 g/l.
FIG. 9 shows lovastatin levels produced by MF172 harboring a vector expressing various lovE variants. Transformants containing empty vector (n=12) produced between 2.6 and 3.75 g/l of lovastatin, with an average of approximately 3.3 g/l Transformants containing At242 (n=12) produced between 1.75 and 4.4 g/l of lovastatin. Transformants containing lovE variant AT32403A4 (n=24) produced between 0.66 and 5 g/l of lovastatin.
