Transition state mimicry: Kinetic data from synthetic aryl unsaturated glycosides and unsaturated glucuronyl fluorides provide evidence for a positively charged transition state in Clostridium perfringens unsaturated glucuronyl hydrolase. Testing of inhibitors based on this transition state showed poor inhibition and suggests that the current model is incomplete.
过渡态模拟:合成芳基不饱和糖苷和不饱和葡糖醛酸氟的动力学数据为产气荚膜梭菌不饱和葡糖醛酸水解酶中带正电的过渡态提供了证据。基于此过渡状态的抑制剂测试显示抑制作用较弱,表明当前模型不完整。
