The defining characteristic of non-ribosomal peptide synthetases is their modular organization. Each NRPS complex is typically composed of multiple modules, and within each module, specific functional domains are responsible for distinct steps in the synthesis.Structural Biology of Non-Ribosomal Peptide Synthetases - PMC The core domains generally include:
* Adenylation (A) domain: Selects and activates the specific amino acid or precursor building block.Evolution-inspired engineering of nonribosomal peptide ...
* Thiolation (T) domain, also known as peptidyl carrier protein (PCP): Covalently attaches the activated building block to itself via a phosphopantetheine arm.Nonribosomal peptide
* Condensation (C) domain: Catalyzes the formation of the peptide bond between the growing peptide chain and the newly activated building block.
Additional domains can be present, such as epimerization domains for altering stereochemistry, methylation domains for adding methyl groups, and thioesterase (TE) domains that often catalyze the release of the completed peptide, sometimes in a cyclic form作者：Z Li·2024·被引用次数：4—Nonribosomal peptide synthetases (NRPSs) aremultienzyme complexes that produce natural products(nonribosomal peptides, NRPs) with enormous chemical ....

Subsequent modules then sequentially add further activated precursors作者：M Strieker·2010·被引用次数：584—Nonribosomal peptide synthetases (NRPSs) arelarge multimodular biocatalyststhat utilize complex regiospecific and stereospecific reactions to assemble .... The C domain of one module catalyzes the formation of a peptide bond with the growing chain held by the T domain of the next module. This chain elongation continues module by module. Finally, a TE domain at the end of the NRPS complex typically cleaves the completed peptide from the enzyme, often resulting in cyclization or other modifications that yield the final nonribosomal peptide product作者：BR Miller·2016·被引用次数：211—Thenon-ribosomal peptide synthetasesare modular enzymes that catalyze synthesis of important peptide products from a variety of standard and ....
The nonribosomal peptide synthetic route is responsible for the production of an astonishing variety of secondary metabolites with diverse and often potent bioactivities. Many clinically important drugs, including antibiotics (e.g., penicillin, vancomycin), immunosuppressants (eRefining and expanding nonribosomal peptide synthetase ....g., cyclosporine), and antifungals, are derived from or inspired by these natural products. The ability of NRPSs to incorporate non-proteinogenic amino acids, chemical modifications, and unusual stereochemistries contributes to the structural complexity and functional diversity of the resulting peptides.
