Biosynthesis of Astacus protease, a digestive enzyme from crayfish

  title={Biosynthesis of Astacus protease, a digestive enzyme from crayfish},
  author={G{\"u}nter Vogt and Walter St{\"o}cker and Volker Storch and Robert Zwilling},
For the first time, the site of biosynthesis of a well characterized invertebrate digestive enzyme is localized. The enzyme chosen, Astacus protease, is a zinc-metalfoenzyme occuring in high concentration in the gastric fluid of the freshwater crayfish Astacus astacus. Enzyme production was stimulated in adult crayfish either by feeding or by removal of the gastric fluid. Immunohistochemistry, cytology and investigation with radioactive tracers demonstrate that in the hours following… CONTINUE READING
