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