Abstract

The kinetics for the inactivation of thrombin (EC 3.4.21.5) by a series of peptides containing C-terminal arginyl chloromethane in the presence of substrate were determined. The inhibitor effectiveness was analysed so as to allow for both the evaluation of the affinity with which the enzyme binds the inhibitor before irreversible modification and also the rate of covalent-bond formation between enzyme and inhibitor. The results obtained show that the observed large range in inhibitor effectiveness can be accounted for almost entirely by marked differences in affinity, with only small variations in rates of formation of covalent complex.

摘要

在底物存在的情况下，测定了一系列含有C端精氨酰氯甲烷的肽对凝血酶（EC 3.4.21.5）的失活动力学。分析了抑制剂的有效性，以便评估酶在不可逆修饰之前与抑制剂结合的亲和力，以及酶与抑制剂之间共价键形成的速率。所得结果表明，观察到的抑制剂有效性的大范围差异几乎完全可以由亲和力的显著差异来解释，而共价复合物形成速率的变化很小。
