<Papain> is an <enzyme> used for <proteolysis>, including limited <Papain digestion of IgG>.
It is a <cysteine> <protease>: a catalytic <cysteine> participates directly in peptide-bond <hydrolysis>. Limited digestion can cleave accessible regions while preserving folded domains, which is why carefully interpreted fragment patterns can reveal aspects of <antibody> architecture. <PeptideCutter - Cleavage specificities of selected enzymes and chemicals (ExPASy)>[Papain cleavage-specificity entry]{ref}
