TrypsinTrypsin
Trypsin is a medium sized, globular, digestive serine protease that is synthesized by the pancreas and secreted into the duodenum of the small intestine. Trypsin hydrolyzes peptide bonds based on side chain specificities of the amino acids surrounding the bond to be cleaved. Trypsin's specificity is for the positively charged side chains of lysine and arginine.
StructureStructure
Trypsin's primary structure is a polypeptide chain of 237 amino acids. These amino acids interact with each other mostly through hydrogen bonding to form trypsin's secondary structural units. Trypsin has many important , including two alpha helices (blue), an anti-parallel beta sheet (green), and random coils (gray). The arrows on these elements point toward the carboxy terminus of the protein. These secondary structures interact together to form the fully folded, native trypsin.
