A key characteristic is that each non ribosomal peptide synthetase can typically synthesize only one type of peptide, dictated by the specific arrangement and substrate specificity of its modules作者：M Duban·2022·被引用次数：58—Nonribosomal peptides are microbial secondary metabolitesexhibiting a tremendous structural diversity and a broad range of biological activities.. This precision is crucial for generating the unique structures of nonribosomal peptides.

The journey of non ribosomal peptide synthesis begins with the recognition and activation of specific amino acid or carboxylic acid substrates by adenylation (A) domains. These activated molecules are then transferred to a thiol group on a carrier protein (C) domain. The next critical step involves the condensation (C) domain, which catalyzes the formation of a peptide bond between two activated substrates. Subsequent modification domains, such as epimerization (E) domains for altering stereochemistry, or methylation (MT) domains for adding methyl groups, can further diversify the nascent peptide chain. Finally, a thioesterase (TE) domain is responsible for releasing the completed nonribosomal peptide from the enzyme complex, often resulting in cyclic and/or branched structures. This entire process, as detailed in numerous studies on non ribosomal peptide synthetase structure and function, highlights the elegance of these biological factoriesNonribosomal peptide synthetases and their biotechnological ....

Many clinically important drugs, such as antibiotics like penicillin and vancomycin, and immunosuppressants like cyclosporine, are either directly derived from or inspired by nonribosomal peptides. This underscores the significant biotechnological potential in Penicillium rubens and other microorganisms that harbor NRPS systems. Researchers are actively exploring nonribosomal peptide synthetases and their biotechnological potential for developing new therapeutic agents.

The sheer diversity of nonribosomal peptides is astounding, with NRPS systems capable of producing molecules with large structural and functional diversity. This is partly due to the ability of NRPS to incorporate non-proteinogenic amino acids, D-amino acids, and other unusual building blocks. Furthermore, the modular nature of non ribosomal peptide synthetases has made them attractive targets for evolution-inspired engineering of nonribosomal peptide synthetases. By manipulating the genes encoding these enzymes, scientists can design novel NRPS variants to biosynthesize new peptides with tailored properties.
