Reaction(IUBMB)
Preferential cleavage: Arg!, Lys!
Comment
The single polypeptide chain cattle beta-trypsin is formed from trypsinogen by cleavage of one peptide bond. Further peptide bond cleavages produce alpha and other iso-forms. Isolated as multiple cationic and anionic trypsins [5] from the pancreas of many vertebrates and from lower species including crayfish, insects (cocoonase) and microorganisms (Streptomyces griseus) [3]. Type example of peptidase family S1.
History
EC 3.4.21.4 created 1961 as EC 3.4.4.4, transferred 1972 to EC 3.4.21.4
