WebProteases represent the largest segment of the industrial enzyme market where they are used in detergents, in food processing, in leather and fabric upgrading, as catalysts in organic synthesis, and as therapeutics. Proteases are involved in digesting long protein chains into shorter fragments by splitting the peptide bonds that link amino acid residues. Some detach the terminal amino acids from the protein chain (exopeptidases, such as aminopeptidases, carboxypeptidase A); others attack internal peptide bonds of a protein (endopeptidases, such as trypsin, chymotrypsin, pepsin, papain, elastase).
