CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of varicidin A, an antifungal natural product
CC containing a cis-octahydrodecalin core (PubMed:30609896). The PKS
CC module of pvhA together with the enoylreductase pvhC catalyze the
CC formation of the polyketide unit which is then conjugated to L-
CC isoleucine by the condensation domain of the NRPS module
CC (PubMed:30609896). Activity of the Dieckmann cyclase domain (RED) of
CC pvhA results in release of an acyclic tetramate (PubMed:30609896). The
CC cytochrome P450 monooxygenase pvhE then catalyzes the oxidation of the
CC C21 methyl group to a to carboxylate group (PubMed:30609896). The
CC methyltransferase pvhD then further methylates the pvhE product
CC (PubMed:30609896). The Diels-Alderase pvhB is able to catalyzes Diels-
CC Alder cycloaddition using both pvhE and pvhD products as substrates to
CC form the decalin ring, yielding varicidin B and A, respectively
CC (PubMed:30609896). {ECO:0000269|PubMed:30609896}.
