Understanding the Diversity of Peptide Natural Products
The structural diversity of peptide natural products is immense, stemming from variations in amino acid sequences, post-translational modifications, and intricate three-dimensional folding.作者：JM Pelton·2024·被引用次数：13—Canonical and Non-Canonical Amino Acids inPeptide Natural Products. Given the bulk biophysical properties of the peptide NPs, we sought to assess what mixtures ... These modifications can include the incorporation of non-canonical amino acids, cyclization, and glycosylation, all contributing to their unique physicochemical properties and biological functionsChapter 5: Peptide Natural Products II: Nonribosomal Peptides.
* Ribosomally Synthesized and Post-Translationally Modified Peptides (RiPPs): This class is derived from short precursor peptides encoded by ribosomal genes. Following translation, these precursors undergo extensive modifications by dedicated enzyme systems, leading to a wide spectrum of complex structures. Examples include lantibiotics and bacteriocins, known for their antimicrobial activities.
* Non-Ribosomal Peptides (NRPs): Synthesized by large enzyme complexes called non-ribosomal peptide synthetases (NRPSs), NRPs do not originate from a ribosomal template. This biosynthetic pathway allows for the incorporation of a broader range of amino acids, including D-amino acids and unusual side chains, resulting in highly complex cyclic or linear structures. Many potent antibiotics and immunosuppressants, such as penicillin and cyclosporine, are NRPs.作者：D Buchanan·2025·被引用次数：12—Naturalcyclicpeptides, isolated from variousnaturalsources (i.e., bacteria, fungi, plants, and marine species), have emerged as an interesting biomolecule ...
