"Cysteine-rich proteins (also cysteine-rich peptide, CRP, disulphide-rich peptide) are small proteins that contain a large number of cysteines. These cysteines either cross-link to form disulphide bonds, or bind metal ions by chelation, stabilising the protein's tertiary structure. CRPs include a highly conserved … See more Disulphides In an oxidising environment cysteines cross-link to form disulphide bonds. CRPs that form these typically have an even number of cysteines.

WebApr 8, 2024 · Recently, a novel type of nonsecreted small peptide termed the cysteine-rich transmembrane module (CYSTM) was characterized. As its name implies, this type of peptide is enriched with cysteines and is, therefore, also called a nonsecreted cysteine-rich peptide (NCRP). WebSeveral macrocyclic peptides (∼30 amino acids), with diverse biological activities, have been isolated from the Rubiaceae and Violaceae plant families over recent years. We have significantly expanded the range of known macrocyclic peptides with the discovery of 16 novel peptides from extracts of Viola hederaceae, Viola odorata and Oldenlandia affinis.
