Understanding the Structure of Circular Peptides

The defining feature of circular peptides is their macrocyclic structure. This ring can be formed by linking the amino terminus to the carboxyl terminus of a linear peptide chain, or through side-chain linkages involving amino acid side groups. The specific type of cyclization and the amino acid sequence dictate the peptide's three-dimensional conformation作者：R Jwad·2020·被引用次数：124—Cyclic peptides are promising scaffolds for drug development, attributable in part to their increased conformational order compared to .... This conformational rigidity, compared to the greater flexibility of linear peptides, leads to several advantageous properties. For instance, the defined structure often results in increased stability against enzymatic degradation and improved binding affinity and selectivity for target molecules.
