CC   -!- FUNCTION: Oxidoreductase; part of the gene cluster that mediates the
CC       biosynthesis of macrophorins, isoprenoid epoxycyclohexenones containing
CC       cyclized drimane moieties (PubMed:28926261). The first step of the
CC       pathway is the synthesis of 6-methylsalicylic acid (6-MSA) by the
CC       polyketide synthase macA (PubMed:28926261). 6-MSA is then converted to
CC       m-cresol by the decarboxylase macB (By similarity). The cytochrome P450
CC       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:G3Y423,
CC       ECO:0000269|PubMed:28926261}.
CC   -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC       {ECO:0000269|PubMed:28926261}.
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.
CC       {ECO:0000269|PubMed:28926261}.
CC   -!- SIMILARITY: Belongs to the oxidoreductase OpS7 family. {ECO:0000305}.
