CC -!- FUNCTION: Terpene cyclase; part of the gene cluster B that mediates the
CC biosynthesis of austinol and dehydroaustinol, two fungal meroterpenoids
CC (PubMed:22329759). The first step of the pathway is the synthesis of
CC 3,5-dimethylorsellinic acid by the polyketide synthase ausA
CC (PubMed:22329759). 3,5-dimethylorsellinic acid is then prenylated by
CC the polyprenyl transferase ausN (PubMed:22329759). Further epoxidation
CC by the FAD-dependent monooxygenase ausM and cyclization by the probable
CC terpene cyclase ausL lead to the formation of protoaustinoid A
CC (PubMed:22329759). Protoaustinoid A is then oxidized to spiro-lactone
CC preaustinoid A3 by the combined action of the FAD-binding
CC 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 -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}.
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 paxB family. {ECO:0000305}.
