Advances in the nonribosomal peptide synthetases

Nonribosomal peptide synthetases (NRPS) catalyze the synthesis of nonribosomal peptide (NRP) compounds with structural and functional diversities, including more than 20 marketed drugs. This review focuses on the recent advances in the functional domains of NRPS and their mechanisms of action, as well as the unconventional assembly patterns such as iterative NRPS, module skipping, in trans aminoacylation and tandem adenylation domains. This review provides the theoretical basis for exploring new nonribosomal peptide compounds and the development of new drugs.
