CC -!- FUNCTION: Methyltransferase; part of the gene cluster A that mediates
CC the biosynthesis of austinol and dehydroaustinol, two fungal
CC meroterpenoids (PubMed:22329759). The first step of the pathway is the
CC synthesis of 3,5-dimethylorsellinic acid by the polyketide synthase
CC ausA (PubMed:22329759). 3,5-dimethylorsellinic acid is then prenylated
CC by the polyprenyl transferase ausN (PubMed:22329759). Further
CC epoxidation by the FAD-dependent monooxygenase ausM and cyclization by
CC the probable terpene cyclase ausL lead to the formation of
CC protoaustinoid A (PubMed:22329759). Protoaustinoid A is then oxidized
CC to spiro-lactone preaustinoid A3 by the combined action of the FAD-
CC binding monooxygenases ausB and ausC, and the dioxygenase ausE
CC (PubMed:22329759, PubMed:23865690). Acid-catalyzed keto-rearrangement
CC and ring contraction of the tetraketide portion of preaustinoid A3 by
CC ausJ lead to the formation of preaustinoid A4 (PubMed:22329759). The
CC aldo-keto reductase ausK, with the help of ausH, is involved in the
CC next step by transforming preaustinoid A4 into isoaustinone which is in
CC turn hydroxylated by the P450 monooxygenase ausI to form austinolide
CC (PubMed:22329759). Finally, the cytochrome P450 monooxygenase ausG
CC modifies austinolide to austinol (PubMed:22329759). Austinol can be
CC further modified to dehydroaustinol which forms a diffusible complex
CC with diorcinol that initiates conidiation (PubMed:22234162,
CC PubMed:22329759). Due to genetic rearrangements of the clusters and the
CC subsequent loss of some enzymes, the end products of the Emericella
CC nidulans austinoid biosynthesis clusters are austinol and
CC dehydroaustinol, even if additional enzymes, such as the O-
CC acetyltransferase ausQ and the cytochrome P450 monooxygenase ausR are
CC still functional (PubMed:29076725). {ECO:0000269|PubMed:22234162,
CC ECO:0000269|PubMed:22329759, ECO:0000269|PubMed:23865690,
CC ECO:0000269|PubMed:29076725}.
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|PubMed:22329759}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q3J7D1}.
CC -!- DISRUPTION PHENOTYPE: Impairs the synthesis of austinol and
CC dehydroaustinol (PubMed:22329759). {ECO:0000269|PubMed:22329759}.
CC -!- MISCELLANEOUS: In A.calidoustus, the austinoid gene cluster lies on a
CC contiguous DNA region, while clusters from E.nidulans and P.brasilianum
CC are split in their respective genomes. Genetic rearrangements provoked
CC variability among the clusters and E.nidulans produces the least number
CC of austionoid derivatives with the end products austinol and
CC dehydroaustinol, while P.brasilianum can produce until
CC acetoxydehydroaustin, and A.calidoustus produces the highest number of
CC identified derivatives. {ECO:0000305|PubMed:29076725}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. {ECO:0000305}.
