CC -!- FUNCTION: 6-hydroxytryprostatin B O-methyltransferase; part of the gene
CC cluster that mediates the biosynthesis of fumitremorgins, indole
CC alkaloids that carry not only intriguing chemical structures, but also
CC interesting biological and pharmacological activities
CC (PubMed:23649274). The biosynthesis of fumitremorgin-type alkaloids
CC begins by condensation of the two amino acids L-tryptophan and L-
CC proline to brevianamide F, catalyzed by the non-ribosomal peptide
CC synthetase ftmA (PubMed:16755625). Brevianamide F is then prenylated by
CC the prenyltransferase ftmPT1/ftmB in the presence of dimethylallyl
CC diphosphate, resulting in the formation of tryprostatin B
CC (PubMed:16000710, PubMed:21105662, PubMed:23090579). The three
CC cytochrome P450 monooxygenases, ftmP450-1/ftmC, ftmP450-2/ftmE and
CC ftmP450-3/FtmG, are responsible for the conversion of tryprostatin B to
CC 6-hydroxytryprostatin B, tryprostatin A to fumitremorgin C and
CC fumitremorgin C to 12,13-dihydroxyfumitremorgin C, respectively
CC (PubMed:19226505). The putative methyltransferase ftmMT/ftmD is
CC expected for the conversion of 6-hydroxytryprostatin B to tryprostatin
CC A (Probable). FtmPT2/FtmH catalyzes the prenylation of 12,13-
CC dihydroxyfumitre-morgin C in the presence of dimethylallyl diphosphate,
CC resulting in the formation of fumitremorgin B (PubMed:18683158).
CC Fumitremorgin B is further converted to verruculogen by ftmOx1/ftmF via
CC the insertion of an endoperoxide bond between the two prenyl moieties
CC (PubMed:19763315). In some fungal species, verruculogen is further
CC converted to fumitremorgin A, but the enzymes involved in this step
CC have not been identified yet (Probable). {ECO:0000269|PubMed:16000710,
