Cysteine proteases, also known as thiol proteases, are hydrolase enzymes that degrade proteins. These proteases share a common catalytic mechanism that involves a nucleophilic cysteine thiol in a catalytic triad or dyad. Discovered by Gopal Chunder Roy in 1873, the first cysteine protease to be isolated and characterized was papain, obtained from Carica papaya. Cystein… how a sound is createdWebAbstract. 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.
