At their core, nonribosomal peptide synthetases are large, multimodular enzymes. Each module within an NRPS is specialized for a particular step in the peptide assembly process, typically involving the activation, modification, and condensation of amino acid substrates. This modular architecture allows for immense combinatorial possibilities, leading to the generation of Nonribosomal peptides (NRPs) that often possess unique and valuable properties. These microbial secondary metabolites are distinct from proteins synthesized by ribosomes and are not templated by mRNA.NRPSsp: non-ribosomal peptide synthase substrate predictor

The process of nonribosomal peptide synthesis is initiated by the recognition and activation of specific amino acid substrates by the adenylation (A) domain within the first module. These activated amino acids are then transferred to a phosphopantetheine arm, a crucial cofactor attached to a peptidyl carrier protein (PCP) domainNRPS13 - Nonribosomal peptide synthetase 13. Subsequent modules, through their condensation (C) domains, facilitate the formation of peptide bonds between these activated amino acids.Ribosome Biogenesis is Necessary for Skeletal Muscle Hypertrophy Further modifications, such as epimerization (E) or oxidation, can occur within specific domains, contributing to the structural complexity of the final NRPs.作者：W Suring·2023·被引用次数：8—Nonribosomal peptide synthetases (NRPSs) are a class of cytosolic enzymes thatsynthesize a range of bio-active secondary metabolitesincluding ...
