CC -!- FUNCTION: FAD-dependent monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of paraherquonin, a meroterpenoid with a
CC unique, highly congested hexacyclic molecular architecture
CC (PubMed:27602587). The first step of the pathway is the synthesis of
CC 3,5-dimethylorsellinic acid (DMOA) by the polyketide synthase prhL (By
CC similarity). Synthesis of DMOA is followed by farnesylation by the
CC prenyltransferase prhE, methylesterification by the methyl-transferase
CC prhM, epoxidation of the prenyl chain by the flavin-dependent
CC monooxygenase prhF, and cyclization of the farnesyl moiety by the
CC terpene cyclase prhH, to yield the tetracyclic intermediate,
CC protoaustinoid A (By similarity). The short chain dehydrogenase prhI
CC then oxidizes the C-3 alcohol group of the terpene cyclase product to
CC transform protoaustinoid A into protoaustinoid B (PubMed:27602587). The
CC FAD-binding monooxygenase prhJ catalyzes the oxidation of
CC protoaustinoid B into preaustinoid A which is further oxidized into
CC preaustinoid A1 by FAD-binding monooxygenase phrK (PubMed:27602587).
CC Finally, prhA leads to berkeleydione via the berkeleyone B intermediate
CC (PubMed:27602587, PubMed:29317628). PrhA is a multifunctional
CC dioxygenase that first desaturates at C5-C6 to form berkeleyone B,
CC followed by rearrangement of the A/B-ring to form the cycloheptadiene
CC moiety in berkeleydione (PubMed:27602587, PubMed:29317628).
CC Berkeleydione serves as the key intermediate for the biosynthesis of
CC paraherquonin as well as many other meroterpenoids (Probable). The
CC cytochrome P450 monooxygenases prhB, prhD, and prhN, as well as the
CC isomerase prhC, are probably involved in the late stage of
CC paraherquonin biosynthesis, after the production of berkeleydione
CC (Probable). Especially prhC might be a multifunctional enzyme that
CC catalyzes the D-ring expansion via intramolecular methoxy
CC rearrangement, as well as the hydrolysis of the expanded D-ring
CC (Probable). {ECO:0000250|UniProtKB:Q5ATJ7, ECO:0000269|PubMed:27602587,
