<P> Trypsin ( EC 3.4. 21.4 ) is a serine protease from the PA clan superfamily , found in the digestive system of many vertebrates , where it hydrolyzes proteins . Trypsin is formed in the small intestine when its proenzyme form , the trypsinogen produced by the pancreas , is activated . Trypsin cleaves peptide chains mainly at the carboxyl side of the amino acids lysine or arginine , except when either is followed by proline . It is used for numerous biotechnological processes . The process is commonly referred to as trypsin proteolysis or trypsinisation , and proteins that have been digested / treated with trypsin are said to have been trypsinized . Trypsin was discovered in 1876 by Wilhelm Kühne . </P>
