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