CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of fumiclavanine C, a fungal ergot alkaloid
CC (PubMed:15933009, PubMed:26972831). DmaW catalyzes the first step of
CC ergot alkaloid biosynthesis by condensing dimethylallyl diphosphate
CC (DMAP) and tryptophan to form 4-dimethylallyl-L-tryptophan
CC (PubMed:15870460). The second step is catalyzed by the
CC methyltransferase easF that methylates 4-dimethylallyl-L-tryptophan in
CC the presence of S-adenosyl-L-methionine, resulting in the formation of
CC 4-dimethylallyl-L-abrine (By similarity). The catalase easC and the
CC FAD-dependent oxidoreductase easE then transform 4-dimethylallyl-L-
CC abrine to chanoclavine-I which is further oxidized by EasD in the
CC presence of NAD(+), resulting in the formation of chanoclavine-I
CC aldehyde (PubMed:20039019, PubMed:20526482, PubMed:21409592). EasA
CC reduces chanoclavine-I aldehyde to dihydrochanoclavine-I aldehyde that
CC spontaneously dehydrates to form 6,8-dimethyl-6,7-didehydroergoline
CC (PubMed:20526482). EasG then catalyzes the reduction of 6,8-dimethyl-
CC 6,7-didehydroergoline to form festuclavine (PubMed:20526482).
CC Hydrolysis of festuclavine by easM then leads to the formation of
CC fumigaclavine B which is in turn acetylated by easN to fumigaclavine A
CC (PubMed:26972831). Finally, easL catalyzes the conversion of
CC fumigaclavine A into fumigaclavine C by attaching a dimethylallyl
CC moiety to C-2 of the indole nucleus (PubMed:19672909).

CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000250|UniProtKB:P04798};
CC -!- PATHWAY: Alkaloid biosynthesis; ergot alkaloid biosynthesis.
CC {ECO:0000269|PubMed:26972831}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC protein {ECO:0000255}.
CC -!- INDUCTION: The expression of the ergot alkaloid synthesis cluster which
CC leads to the synthesis of fumigaclavines is positively regulated by the
CC brlA and stuA transcription factors (PubMed:19028996).
CC {ECO:0000269|PubMed:19028996}.
CC -!- DISRUPTION PHENOTYPE: Blocks the ergot alkaloid pathway at
CC festuclavine, and downstream products are eliminated (PubMed:26972831).
CC {ECO:0000269|PubMed:26972831}.
CC -!- BIOTECHNOLOGY: Ergot alkaloids are known for their toxic effects on
CC humans who consume contaminated grains or livestock that graze on
CC grasses harboring ergot alkaloid-producing fungi (PubMed:19523108). Due
CC to their strong affinity for monoamine neurotransmitter receptors they
CC may also have clinical uses such as treatment of migraines, Parkinson's
CC disease and cerebrovascular insufficiency (PubMed:19523108).
CC {ECO:0000305|PubMed:19523108}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
