CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of the indole diterpenes penitrems
CC (PubMed:26213965). The geranylgeranyl diphosphate (GGPP) synthase penG
CC catalyzes the first step in penitrem biosynthesis via conversion of
CC farnesyl pyrophosphate and isopentyl pyrophosphate into geranylgeranyl
CC pyrophosphate (GGPP) (Probable). Condensation of indole-3-glycerol
CC phosphate with GGPP by the prenyl transferase penC then forms 3-
CC geranylgeranylindole (3-GGI) (Probable). Epoxidation by the FAD-
CC dependent monooxygenase penM leads to a epoxidized-GGI that is
CC substrate of the terpene cyclase penB for cyclization to yield
CC paspaline (Probable). Paspaline is subsequently converted to 13-
CC desoxypaxilline by the cytochrome P450 monooxygenase penP, the latter
CC being then converted to paxilline by the cytochrome P450 monooxygenase
CC penQ (PubMed:26213965). Paxilline is converted to beta-paxitriol via C-
CC 10 ketoreduction by the short-chain dehydrogenase PC-15 which can be
CC monoprenylated at the C-20 by the indole diterpene prenyltransferase
CC penD (Probable). A two-step elimination (acetylation and elimination)
CC process performed by the O-acetyltransferase PC-16 and the
CC P.simplicissimum ptmI-ortholog not yet identified in P.crustosum, leads
CC to the production of the prenylated form of penijanthine (Probable).
CC The FAD-linked oxidoreductase ptmO then converts the prenylated form of
CC penijanthine into PC-M5 which is in turn transformed into PC-M4 by the
CC aromatic dimethylallyltransferase PC-22 (Probable). A series of
CC oxidation steps involving 4 cytochrome P450 monooxygenases (PC-21, PC-
CC 05, PC-23, PC-20) and a FAD-dependent monooxygenase (PC-14) are
CC required for the transformation of PC-M4 to penitrems A and E.
CC Synthesis of these final products is proposed to proceed via penitrems
CC D and C (PC-21, PC-05, PC-14) and penitrems B and F (PC-21, PC-05, PC-
CC 14, PC-23) (Probable). {ECO:0000269|PubMed:26213965,
