CC   -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC       mediates the biosynthesis of pyranonigrins, a family of antioxidative
CC       compounds (PubMed:24106156, PubMed:26414728). The first step of
CC       pyranonigrins biosynthesis is performed by the hybrid PKS-NRPS
CC       synthetase that condenses 6 malonyl-CoA units to an acetyl starter
CC       unit, to form a 1,3,5-trioxotetradecane-6,8-dienyl-ACP
CC       (PubMed:24106156). The enoyl reducrase (ER) domain of pynA is likely to
CC       be functional during the first two rounds of polyketide chain
CC       extension, to generate the saturated C-C bonds of the alkyl side chain
CC       (Probable). PynA subsequently forms the amide bond between the acyl
CC       chain and L-serine (PubMed:24106156, PubMed:26414728). Although pynA
CC       has a terminal reductase domain, it appears to require the thioesterase
CC       pynI for the release of the straight-chain intermediate from pynA via
CC       the formation of a tetramic acid pyranonigrin J (PubMed:26414728). The
CC       methyltransferase pynC then coverts pyranonigrin J to pyranonigrin I
CC       via N-methylation (PubMed:26414728). The FAD-dependent monooxygenase
CC       pynG catalyzes an epoxidation-mediated cyclization to form the dihydro-
CC       gamma-pyrone moiety, followed by pynD-catalyzed oxidation of the
CC       alcohol to the ketone and enolization to yield the characteristic
CC       tetramic acid-fused gamma-pyrone core of pyranonigrin H
CC       (PubMed:26414728). Pyranonigrin H is substrate of pynH for dehydration-
CC       mediated exo-methylene formation from the serine side chain to produce
CC       pyranonigrin E, before the oxidase pynE reduces the exo-methylene of
CC       pyranonigrin E into a pendant methyl to form pyranonigrin G
CC       (PubMed:26414728). The FAD-linked oxidoreductase pynB performs the
CC       reverse reaction and converts pyranonigrin G back to pyranonigrin E
CC       (PubMed:26414728). {ECO:0000269|PubMed:24106156,
