CC -!- FUNCTION: O-Mevalon transferase; part of the gene cluster that mediates
CC the biosynthesis of macrophorins, isoprenoid epoxycyclohexenones
CC containing cyclized drimane moieties (PubMed:28926261). The first step
CC of the pathway is the synthesis of 6-methylsalicylic acid (6-MSA) by
CC the polyketide synthase macA (PubMed:28926261). 6-MSA is then converted
CC to m-cresol by the decarboxylase macB (By similarity). The cytochrome
CC P450 monooxygenase macC then catalyzes the oxidation of m-cresol to
CC toluquinol (By similarity). Epoxidation of toluquinol is then performed
CC by the short chain dehydrogenase macD, with the help of macE, and a
CC further prenylation by macG leads to 7-deacetoxyyanuthone A (By
CC similarity). The next step is the hydroxylation of C-22 of 7-
CC deacetoxyyanuthone A by the cytochrome P450 monooxygenase macH to yield
CC 22-deacetylyanuthone A (By similarity). O-Mevalon transferase macI then
CC attaches mevalon to the hydroxyl group of 22-deacetylyanuthone A to
CC produce yanuthone E (By similarity). The terpene cyclase macJ catalyzes
CC the cyclization of 22-deacetylyanuthone A to macrophorin A
CC (PubMed:28926261). MacJ is also able to catalyze cyclization of
CC yanuthone E and 7-deacetoxyyanuthone A to their corresponding
CC macrophorins (PubMed:28926261). The macJ products can be further
CC modified by macH and macJ, as well as by the FAD-dependent
CC monooxygenase macF, to produce additional macrophorins, including 4'-
CC oxomacrophorin A, 4'-oxomacrophorin D and 4'-oxomacrophorin E
CC (PubMed:28926261). {ECO:0000250|UniProtKB:G3Y421,
CC ECO:0000269|PubMed:28926261}.
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|PubMed:28926261}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}.
CC -!- MISCELLANEOUS: The macrophorins cluster contains a single gene
CC insertion (encoding for the terpene cyclase macJ) compared with the
CC yanuthone cluster that produces the linear compound yanuthone.
