CC   -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster B
CC       that mediates the biosynthesis of austinol and dehydroaustinol, two
CC       fungal meroterpenoids (PubMed:22329759). The first step of the pathway
CC       is the synthesis of 3,5-dimethylorsellinic acid by the polyketide
CC       synthase ausA (PubMed:22329759). 3,5-dimethylorsellinic acid is then
CC       prenylated by the polyprenyl transferase ausN (PubMed:22329759).
CC       Further epoxidation by the FAD-dependent monooxygenase ausM and
CC       cyclization by the probable terpene cyclase ausL lead to the formation
CC       of protoaustinoid A (PubMed:22329759). Protoaustinoid A is then
CC       oxidized to spiro-lactone preaustinoid A3 by the combined action of the
CC       FAD-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         Evidence={ECO:0000250|UniProtKB:P04798};
CC   -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC       {ECO:0000269|PubMed:22329759}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC       protein {ECO:0000255}.
CC   -!- DISRUPTION PHENOTYPE: Impairs the synthesis of austinol and
CC       dehydroaustinol and accumulates the intermediate compound austinolide
CC       (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 cytochrome P450 family. {ECO:0000305}.
