CC -!- FUNCTION: Fumigatonoid B endoperoxide isomerase; part of the gene
CC cluster that mediates the biosynthesis of novofumigatonin, a heavily
CC oxygenated meroterpenoid containing a unique orthoester moiety
CC (PubMed:29968715). The first step of the pathway is the synthesis of
CC 3,5-dimethylorsellinic acid (DMOA) by the polyketide synthase nvfA via
CC condensation of one acetyl-CoA starter unit with 3 malonyl-CoA units
CC and 2 methylations (PubMed:29968715). DMOA is then converted to
CC farnesyl-DMOA by the farnesyltransferase nvfB (PubMed:29968715).
CC Epoxydation by FAD-dependent monooxygenase nvfK, followed by a
CC protonation-initiated cyclization catalyzed by the terpene cyclase nvfL
CC leads to the production of asnavolin H (PubMed:29968715). The short
CC chain dehydrogenase nvfC then as a 3-OH dehydrogenase of asnovolin H to
CC yield chemesin D (PubMed:29968715). There are two branches to
CC synthesize asnovolin A from chemesin D (PubMed:29968715). In one
CC branch, chemesin D undergoes Baeyer-Villiger oxidation by nvfH,
CC methylation by nvfJ, and enoyl reduction by the nvfM D enoylreductase
CC that reduces the double bond between C-5'and C-6', to form respectively
CC asnovolin I, asnovolin K, and asnovolin A (PubMed:29968715). In the
CC other branch, the methylation precedes the Baeyer-Villiger oxidation
CC and the enoyl reduction to yield asnovolin A via the asnovolin J
CC intermediate (PubMed:29968715). Asnovolin A is further converted to
CC fumigatonoid A by the Fe(II)/2-oxoglutarate-dependent dioxygenase nvfI
CC that catalyzes an endoperoxidation reaction (PubMed:29968715). The
CC alpha/beta hydrolase nvfD then acts as an epimerase that converts
CC fumigatonoid A to its C-5' epimer, which then undergoes spontaneous or
CC nvfD-catalyzed lactonization (PubMed:29968715). The following step
CC utilizes the ketoreductase nvfG to produce fumigatonoid B
CC (PubMed:29968715). The dioxygenase nvfE further converts fumigatonoid B
CC into fumigatonoid C (PubMed:29968715). Finally the Fe(II)/2-
CC oxoglutarate-dependent dioxygenase nvfF catalyzes two rounds of
CC oxidation to transform fumigatonoid C into the end product,
CC novofumigatonin A (PubMed:29968715). {ECO:0000269|PubMed:29968715}.
