WebNov 23, 2024 · Thiols are a good choice as a reactive group because of their levels of nucleophilicity and their participation in radical-mediated reactions. Because thiols are optimally reactive and naturally abundant, thiol-based chemistry is an obvious choice for protein modification. 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. Cysteine …
