Effects of ionizing radiations on enzymes: The influence of gamma and x-irradiation on phosphatases and aerobic phosphorylation
In recent studies on the effects of ionizing radiations on enzymatic reactions we observed that the rate of hydrolysis of certain phosphate esters by alkaline phosphates was increased after exposure of mice to lethal doses of gamma radiation and X-rays. In our experiments no change in the adenosine triphosphatase activity of several tissues was noted after irradiation but the hydrolysis of {beta}-glycerophosphate and 5-adenylic acid was significantly increased in some tissues. To obtain further information on the nature and extent of the increase in phosphatase activity of tissues after irradiation we have continued investigations on alkaline phosphatases. 13 refs., 1 fig., 7 tabs.
