Kinetic measurements were performed to test the effect of uranyl ions on the enzymatic hydrolysis of pyrophosphate. A strong inhibition of the enzyme was found. From a Dixon-plot an inhibition competitive to the substrate magnesium pyrophosphate and an inhibitory constant of Ki = 3 . 10(-7) M was deduced.
进行动力学测量以测试铀酰离子对焦磷酸酶促水解的影响。发现该酶受到强烈抑制。从狄克逊图中推断出对底物焦磷酸镁具有竞争性抑制作用,抑制常数Ki = 3×10⁻⁷ M。
