CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster A
CC that mediates the biosynthesis of botcinic acid and its botcinin
CC derivatives, acetate-derived polyketides that contribute to virulence
CC when combined with the sesquiterpene botrydial (PubMed:18208491,
CC PubMed:21722295). Botcinic acid and its derivatives have been shown to
CC induce chlorosis and necrosis during host plant infection, but also
CC have antifungal activities (PubMed:18208491, PubMed:21722295). Two
CC polyketide synthases, BOA6 and BOA9, are involved in the biosynthesis
CC of botcinins. BOA6 mediates the formation of the per-methylated
CC tetraketide core by condensation of four units of malonyl-CoA with one
CC unit of acetyl-CoA, which would be methylated in activated methylene
CC groups to yield a bicyclic acid intermediate that could then either be
CC converted to botrylactone derivatives or lose the starter acetate unit
CC through a retro-Claisen type C-C bond cleavage to yield botcinin
CC derivatives (PubMed:23203902). The second polyketide synthase, BOA9, is
CC probably required for the biosynthesis of the tetraketide side chain of
CC botcinins (Probable). The methyltransferase (MT) domain within BOA6 is
CC probably responsible for the incorporation of four methyl groups
CC (Probable). The trans-enoyl reductase BOA5 might take over the enoyl
CC reductase function of BOA6 that misses an ER domain (Probable). The
CC monooxygenases BOA2, BOA3 and BOA4 might be involved in further
CC hydroxylations at C4, C5 and C8, whereas BOA7, close to BOA9, could
CC potentially be involved in the hydroxylation at C4 in the side chain of
CC botcinins (Probable). {ECO:0000269|PubMed:18208491,
