Functional Classification and Experimental Applications of Cysteine Endopeptidases: Plant Proteases, Cathepsins, and Arg-Specific Endoproteases

Cysteine endopeptidases are a class of proteases in which a catalytic cysteine residue participates in peptide bond hydrolysis. They include plant-derived proteolytic enzymes, lysosomal cathepsins, and endoproteases with specific cleavage-site preferences. Papain, ficin, and chymopapain are ...
