Proteolytic cleavage of proteins by proteases plays a critical role in numerous biological processes. The main difference between chymotrypsin and trypsin is the amino acids they select for.Chymotrypsin is the enzyme that selects for the aromatic amino acids: phenylalanine, tryptophan, and tyrosine.Trypsin is the enzyme that selects for the basic amino acids: lysine and arginine. Proteolytic cleavage or proteolysis is the enzymatic hydrolysis of a peptide bond in a peptide or protein substrate by a family of specialized enzymes termed proteases.

How is proteolytic cleavage a post-translational modification? Proteolytic cleavage, the hydrolysis of peptide bonds in a protein, is a ubiquitous reaction in nature catalyzed by enzymes called peptidases (also referred to as proteases, proteinases, and proteolytic enzymes ). A protease (also called a peptidase or proteinase) is any enzyme that performs proteolysis, that is, begins protein catabolism by hydrolysis of the peptide bonds that link amino acids together in a polypeptide chain.Proteases have evolved multiple times, and different classes of protease can perform the same reaction by completely different catalytic mechanisms. The different proteolytic cleavage mechanisms of DNlg2 and mammal Nlg1 suggest a variety of potential regulation manners for Nlg cleavage. Journal of Cell Science, 2010.
