"WebTrypsin, chymotrypsin, and elastase are collectively called protein scissors. They cleave the protein bonds and release the amino acids. Each one of these enzymes cut the proteins at specific places of amino acid. Namely the trypsin cleaves at the end of lysine and arginine. Chymotrypsin cuts near the large amino acids and phenylalanine. " - Trypsin enzyme substrate
