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 ...

Papain is one of the most representative cysteine proteases in the latex of unripe papaya fruit. With relatively mild reaction conditions, broad substrate tolerance, and good formulatability, it has long supported applications in food processing, industrial processing aids, biological sample ...
Papain is an enzyme with a protein hydrolytic function and cysteine protease activity. The enzyme belongs to a superfamily that consists of a single polypeptide chain containing three disulfide bonds and a sulfhydryl group essential for enzymatic activity and is derived from the green papaya， ...
