EC 18.104.22.168 - Trypsin
IntEnz Enzyme Nomenclature
sperm receptor hydrolase
- Preferential cleavage: Arg┼, Lys┼.
The single polypeptide chain cattle β-trypsin is formed from trypsinogen by cleavage of one peptide bond. Further peptide bond cleavages produce α and other iso-forms. Isolated as multiple cationic and anionic trypsins  from the pancreas of many vertebrates and from lower species including crayfish, insects (cocoonase) and microorganisms (Streptomyces griseus) . Type example of peptidase family S1. Formerly EC 22.214.171.124.
