WebCysteine proteases generally may be assigned to one of the following four groups according to their side chain specificities: (1) papain-like (includes clostripain and streptopain), (2) trypsin-like with preference for cleavage at the arginine residue, (3) specific to glutamic acid, and (4) others. Most have neutral pH optima. WebAlkaline hydrolysis typically uses NaOH or KOH as the reagent. However, alkaline hydrolysis cannot replace acid hydrolysis for the quantitation of all amino acids.
