WebSulfhydryls, also called thiols, exist in proteins in the side-chain of cysteine (Cys, C) amino acids. Pairs of cysteine sulfhydryl groups are often linked by disulfide bonds (–S–S–) within or between polypeptide chains as the basis of native tertiary or quaternary protein structure. WebAbstract. Cysteine proteases represent one of the four main groups of peptide-bond hydrolases. They all use a S − anion of a cysteine side chain as the nucleophile in peptide-bond hydrolysis. Cysteine proteases are found in all forms of life and mediate a wide variety of physiological and pathological processes, from the bulk digestion of ...
