| Résumé : | Using histochemical techniques, trypsin and chymotrypsin-like proteases have been detected in the gland cells of enteroids in the gastroderm of Cerianthus lloydi Gosse. These enzymes seem to be concentrated in granules resembling the zymogen granules of mammalian pancreas; the mechanisms of synthesis and the form of their membranes seem to be the same. Trypsin and chymotrypsin of C. lloydi resemble the vertebrates enzymes with respect to their properties and reaction with certain substrates and inhibitors. Trypsin appears to exist as an inactive precursor in the gastroderm of C. lloydi with spontaneous activation at 25°C. © 1975. |
