CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of fungal ergot alkaloid (PubMed:10071219,
CC PubMed:14732265, PubMed:14700635, PubMed:15904941, PubMed:17308187,
CC PubMed:17720822). DmaW catalyzes the first step of ergot alkaloid
CC biosynthesis by condensing dimethylallyl diphosphate (DMAP) and
CC tryptophan to form 4-dimethylallyl-L-tryptophan (PubMed:14732265). The
CC second step is catalyzed by the methyltransferase easF that methylates
CC 4-dimethylallyl-L-tryptophan in the presence of S-adenosyl-L-
CC methionine, resulting in the formation of 4-dimethylallyl-L-abrine (By
CC similarity). The catalase easC and the FAD-dependent oxidoreductase
CC easE then transform 4-dimethylallyl-L-abrine to chanoclavine-I which is
CC further oxidized by easD in the presence of NAD(+), resulting in the
CC formation of chanoclavine-I aldehyde (PubMed:20118373,
CC PubMed:21409592). Agroclavine dehydrogenase easG then mediates the
CC conversion of chanoclavine-I aldehyde to agroclavine via a non-
CC enzymatic adduct reaction: the substrate is an iminium intermediate
CC that is formed spontaneously from chanoclavine-I aldehyde in the
CC presence of glutathione (PubMed:20735127, PubMed:21494745). The
CC presence of easA is not required to complete this reaction
CC (PubMed:21494745). Further conversion of agroclavine to paspalic acid
CC is a two-step process involving oxidation of agroclavine to
CC elymoclavine and of elymoclavine to paspalic acid, the second step
CC being performed by the elymoclavine oxidase cloA (PubMed:16538694,
CC PubMed:17720822). Paspalic acid is then further converted to D-lysergic
CC acid (PubMed:15904941). Ergopeptines are assembled from D-lysergic acid
CC and three different amino acids by the D-lysergyl-peptide-synthetases
CC composed each of a monomudular and a trimodular nonribosomal peptide
CC synthetase subunit (PubMed:14700635, PubMed:15904941). LpsB and lpsC
CC encode the monomodular subunits responsible for D-lysergic acid
CC activation and incorporation into the ergopeptine backbone
CC (PubMed:14700635). LpsA1 and A2 subunits encode the trimodular
CC nonribosomal peptide synthetase assembling the tripeptide portion of
CC ergopeptines (PubMed:14700635). LpsA1 is responsible for formation of
CC the major ergopeptine, ergotamine, and lpsA2 for alpha-ergocryptine,
CC the minor ergopeptine of the total alkaloid mixture elaborated by
CC C.purpurea (PubMed:17560817, PubMed:19139103). D-lysergyl-tripeptides
CC are assembled by the nonribosomal peptide synthetases and released as
CC N-(D-lysergyl-aminoacyl)-lactams (PubMed:24361048). Cyclolization of
CC the D-lysergyl-tripeptides is performed by the Fe(2+)/2-ketoglutarate-
CC dependent dioxygenase easH which introduces a hydroxyl group into N-(D-
CC lysergyl-aminoacyl)-lactam at alpha-C of the aminoacyl residue followed
CC by spontaneous condensation with the terminal lactam carbonyl group
CC (PubMed:24361048). {ECO:0000250|UniProtKB:Q50EL0,

CC -!- DISRUPTION PHENOTYPE: Causes a blockage in the conversion of clavines
CC to D-lysergic acid (PubMed:16538694). Abolishes the production of the
CC peptide alkaloids ergotamine and ergocryptine but accumulates
CC substantial amounts agroclavine accompanied by varying amounts of
CC elymoclavine and chanoclavine which ranged between 10 and 20 percent of
CC the amount of agroclavine formed (PubMed:16538694). Leads also to
