CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of the meroterpenoids nectripenoids A and B,
CC as well as cochliquninone D and isocochliquninone E (PubMed:29797385).
CC The pathway probably begins with the HR-PKS ntnH that catalyzes two
CC chain-extension steps to form a reduced triketide, which then primes
CC the SAT domain in the NR-PKS ntnG to initiate three more cycles of
CC extension to give a linear hexaketide corresponding to the polyketide
CC part of nectripenoids (Probable). The FAD-dependent monooxygenase ntnJ
CC then performs an oxidative decarboxylation at C11 of the ntnH/ntnG
CC product, via an electrophilic aromatic hydroxylation with concomitant
CC ipso-decarboxylation (Probable). The membrane-bound polyprenyl
CC transferase ntnF then introduces a farnesyl group before the FAD-
CC dependent monooxygenase ntnK functions as the first epoxidase on
CC terminal C12'-C13' olefin, followed by a second epoxidation on C7'-C8'
CC catalyzed by ntnA (Probable). The terpene cyclase/mutase ntnI then
CC initiates the sequential tricyclic ring formation through protonation
CC of the terminal epoxide and catalyzes the regioselective and
CC stereoselective 6/6/6-tricyclic ring formation (Probable). The
CC cytochrome P450 monooxygenase ntnM may then hydroxylate C1' (Probable).
