WebPapain (EC 3.4.22.2) is a cysteine protease acquired from the latex of the papaya plant (Carica papaya) and has been used for protecting plants against insects ( Konno et al., 2004 ). The enzyme has been reported to have a high optimal temperature (65°C) and a wide pH range (5–8) for its activity ( Smith and Hong-Shum, 2003 ). WebCysteine proteases, also known as papain-like or thiol proteases, have a catalytic dyad comprising Cys and His residues in close proximity that interact with each other. During proteolysis, the Cys sulfhydryl group acts as a nucleophile to initiate attack on the carbonyl carbon of the peptide bond to be hydrolyzed.
