Featured Products
Papain (CAS 9001-73-4) is a cysteine protease belonging to the peptidase C1 family derived primarily from papaya latex. Mechanistically, it catalyzes the hydrolytic cleavage of peptide bonds via nucleophilic attack facilitated by an active-site cysteine residue. Due to its proteolytic activity, papain is utilized extensively in biomedical research, particularly in studies of protein structure, enzymatic processing, and antibody digestion protocols. Additionally, its enzymatic properties have supported applications across pharmaceutical, food processing, textile, and cosmetic fields.
