| the thermal properties of intestinal alkaline phosphatase of three kinds of deep-water fish. | 1. the thermal properties of intestinal alkaline phosphatase were investigated with three species of deep-water fish in the temperature range of 0-70 c. 2. a relationship was found between the thermal stability of the enzyme and the fish origin. 3. maximum activity of alkaline phosphatase of the fish that originated in tropical water, namely, aphanopus carbo and epigonus telescopus was 60 c, whereas the respective maximum enzyme activity of etmopterus princeps that originated in the burial zone ... | 1989 | 2598626 |
