CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of pyranoviolin A, a pyranonigrin analog with
CC a C-3 methoxy group (PubMed:33117309). Initially, the PKS portion of
CC pyvA synthesizes C-10 carbon chain from 5 molecules of malonyl-CoA,
CC which is then condensed with the thiolation (T) domain-bound glycine
CC activated by the adenylation (A) domain (PubMed:33117309). The
CC subsequent chain release by Dieckmann condensation (DKC) could be
CC catalyzed by the TE domain present at the C-terminus of pyvA and/or the
CC alpha/beta hydrolase pyvD, installing the tetramic acid moiety
CC (Probable). The FAD-dependent monooxygenase pyvC next epoxidizes one of
CC the olefins of the polyketide part, and the epoxide ring-opening
CC induces the dihydro-gamma-pyrone ring formation (Probable). The
CC cytochrome P450 monooxygeanse pyvB would be responsible for the 2
CC consecutive reactions, in which the dihydro-gamma-pyrone is oxidized to
CC gamma-pyrone and C-7 is hydroxylated to yield pyranonigrin F
CC (Probable). Finally, the O-methyltransferase pyvH methylates the C-3
CC hydroxy group to complete the biosynthesis (Probable).
