Status
Functioni
Nonribosomal peptide synthetase; part of the gene cluster that mediates the biosynthesis of sirodesmin PL, an epipolythiodioxopiperazine (ETP) characterized by a disulfide bridged cyclic dipeptide and that acts as a phytotoxin which is involved in the blackleg didease of canola (PubMed:15387811, PubMed:18272357, PubMed:19762440). SirD catalyzes the O-prenylation of L-tyrosine (L-Tyr) in the presence of dimethylallyl diphosphate (DMAPP) to yield 4-O-dimethylallyl-L-Tyr, and therefore represents probably the first pathway-specific enzyme in the biosynthesis of sirodesmin PL (PubMed:19762440, PubMed:21038099, PubMed:24083562). 4-O-dimethylallyl-L-Tyr, then undergoes condensation with L-Ser in a reaction catalyzed by the non-ribosomal peptide synthase sirP to form the diketopiperazine (DKP) backbone (PubMed:18272357). Further bishydroxylation of the DKP performed by the cytochrome P450 monooxygenase sirC leads to the production of the intermediate phomamide (PubMed:27390873). This step is essential to form the reactive thiol group required for toxicity of sirodesmin PL (PubMed:27390873). The next steps of sirodesmin biosynthesis are not well understood yet, but some predictions could be made from intermediate compounds identification (PubMed:18272357). Phomamide is converted into phomalizarine via oxidation, probably by sirT (PubMed:18272357). Further oxidation, methylation (by sirM or sirN) and reduction steps convert phomalizarine to deacetyl sirodesmin (PubMed:18272357). Finally, acetyltransferase sirH probably acetylates deacetyl sirodesmin to produce sirodesmin PL (PubMed:18272357).2 Publications4 Publications

Domaini
NRP synthetases are composed of discrete domains (adenylation (A), thiolation (T) or peptidyl carrier protein (PCP) and condensation (C) domains) which when grouped together are referred to as a single module (By similarity). Each module is responsible for the recognition (via the A domain) and incorporation of a single amino acid into the growing peptide product (By similarity). Thus, an NRP synthetase is generally composed of one or more modules and can terminate in a thioesterase domain (TE) that releases the newly synthesized peptide from the enzyme (By similarity). Occasionally, epimerase (E) domains (responsible for L- to D-amino acid conversion) are present within the NRP synthetase (By similarity). NRPS10 has the foolowing architecture: A-T-C-A-T-C (PubMed:15387811).By similarity1 Publication
