Can cysteine form disulfide bonds
WebDisulfide bonds are made in nearly one-third (7000) of the proteins in the eukaryotic proteome,11 many of which are destined for contact with the relatively nonreducing extracellular environment as secretory or cell surface proteins. Disulfide bond formation involves a reaction between the sulfhydryl (SH) side chains of two cysteine residues ... WebWhat can form disulfide bonds? cysteine residues Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative folding.
