General Information

General Information Comment Organism
additional information the enzyme shows completely conserved structural features for catalytic function of trypsins, but possesses the four Met residues, Met135, Met145, Met175, and Met242, in their molecules and the deletion of Tyr151 and substitution of Pro152 for Gly in their autolysis loops Gadus chalcogrammus
