Target type: molecularfunction
Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile. [GOC:mah, https://www.ebi.ac.uk/merops/about/glossary.shtml#CATTYPE]
Cysteine-type peptidase activity is a molecular function characterized by the ability of an enzyme to cleave peptide bonds within a protein or polypeptide chain. This activity is mediated by the catalytic action of a cysteine residue, which acts as a nucleophile in the reaction. The cysteine residue is typically located within a conserved catalytic triad, consisting of a cysteine, a histidine, and an aspartic acid residue. The reaction mechanism involves the formation of a covalent intermediate between the cysteine residue and the peptide substrate. This intermediate is then hydrolyzed, releasing the cleaved peptide and regenerating the active enzyme. Cysteine-type peptidases are involved in a wide range of biological processes, including protein degradation, signal transduction, and immune response. They are also implicated in various diseases, including cancer, Alzheimer's disease, and HIV infection.'
