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 …
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.
