IUBMB Comments

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.

The expected taxonomic range for this enzyme is: Bacteria, Eukaryota
