evaluated as transition state analogue inhibitors for thermolysin. A linear correlation is observed between the K(i) values of these inhibitors and the kinetic parameters (K(M)/k(cat)) of the parallel series of related substrates, satisfying the criterion stipulated for transition state analogue inhibitors by Bartlett and Marlowe. Furthermore, examination of the binding mode of a related reversed hydroxamate
已经评估了一系列带有反向异羟肟酸酯部分的抑制剂作为嗜热菌素的过渡态类似物抑制剂。观察到这些抑制剂的K(i)值与平行系列相关底物的动力学参数(K(M)/ k(cat))之间存在线性相关性,满足Bartlett和他对过渡态类似物抑制剂规定的标准。马洛 此外,与假定的酶催化蛋白水解反应的过渡态相比,对相关的带有反向异羟肟酸酯的嗜热菌素抑制剂的结合模式的研究表明,所研究的抑制剂模拟了过渡态的电子和几何特征。
