Aminotripeptidase (EC E.4.1.3) activity in the digestive system of some teleost fishes.
Aminotripeptidase (EC 3.4.1.3) has been found to be present in the intestinal mucosa, hepatopancreas and the pyloric caeca of the three fished examined. The pH optimum of the enzyme ranges from 6.6 to 7.6. The pH optimum varies from species to species and also from section to section of the gut in the same species. The enzyme is most active in the carnivorous Channa gachua in comparison to the other fishes studied.
