Cystine rich peptides
WebCystine-knot peptides are attractive templates in drug discovery due to a number of features they possess including their 3D conformation, … WebAn inhibitor cystine knot (aka ICK or Knottin) is a protein structural motif containing three disulfide bridges. Knottins are one of three folds in the cystine knot motif; the other closely related knots are the Growth Factor Cystine Knot (GFCK) and the Cyclic Cystine Knot (CCK; cyclotide). [2]

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. Metal binding See more CRPs are numerous in plants, with 756 CRP-encoding genes in the Arabidopsis thaliana genome. Several CRPs bind known receptors, but most CRP signaling mechanisms and … See more
