4-dimethylallyltryptophan N-methyltransferase; part of the gene cluster that mediates the biosynthesis of fungal ergot alkaloid (PubMed:10071219, PubMed:14732265, PubMed:14700635, PubMed:15904941, PubMed:17308187, PubMed:17720822). DmaW catalyzes the first step of ergot alkaloid biosynthesis by condensing dimethylallyl diphosphate (DMAP) and tryptophan to form 4-dimethylallyl-L-tryptophan (PubMed:14732265). The second step is catalyzed by the methyltransferase easF that methylates 4-dimethylallyl-L-tryptophan in the presence of S-adenosyl-L-methionine, resulting in the formation of 4-dimethylallyl-L-abrine (By similarity). The catalase easC and the FAD-dependent oxidoreductase easE then transform 4-dimethylallyl-L-abrine to chanoclavine-I which is further oxidized by easD in the presence of NAD+, resulting in the formation of chanoclavine-I aldehyde (PubMed:20118373, PubMed:21409592). Agroclavine dehydrogenase easG then mediates the conversion of chanoclavine-I aldehyde to agroclavine via a non-enzymatic adduct reaction: the substrate is an iminium intermediate that is formed spontaneously from chanoclavine-I aldehyde in the presence of glutathione (PubMed:20735127, PubMed:21494745). The presence of easA is not required to complete this reaction (PubMed:21494745). Further conversion of agroclavine to paspalic acid is a two-step process involving oxidation of agroclavine to elymoclavine and of elymoclavine to paspalic acid, the second step being performed by the elymoclavine oxidase cloA (PubMed:16538694, PubMed:17720822). Paspalic acid is then further converted to D-lysergic acid (PubMed:15904941). Ergopeptines are assembled from D-lysergic acid and three different amino acids by the D-lysergyl-peptide-synthetases composed each of a monomudular and a trimodular nonribosomal peptide synthetase subunit (PubMed:14700635, PubMed:15904941). LpsB and lpsC encode the monomodular subunits responsible for D-lysergic acid activation and incorporation into the ergopeptine backbone (PubMed:14700635). LpsA1 and A2 subunits encode the trimodular nonribosomal peptide synthetase assembling the tripeptide portion of ergopeptines (PubMed:14700635). LpsA1 is responsible for formation of the major ergopeptine, ergotamine, and lpsA2 for alpha-ergocryptine, the minor ergopeptine of the total alkaloid mixture elaborated by C.purpurea (PubMed:17560817, PubMed:19139103). D-lysergyl-tripeptides are assembled by the nonribosomal peptide synthetases and released as N-(D-lysergyl-aminoacyl)-lactams (PubMed:24361048). Cyclolization of the D-lysergyl-tripeptides is performed by the Fe2+/2-ketoglutarate-dependent dioxygenase easH which introduces a hydroxyl group into N-(D-lysergyl-aminoacyl)-lactam at alpha-C of the aminoacyl residue followed by spontaneous condensation with the terminal lactam carbonyl group (PubMed:24361048).By similarity2 Publications12 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
