Substrate- and ligand-induced conformational changes were studied in a series of thiol-modified derivatives of rabbit muscle creatine kinase that retained different amounts of enzymic activity. The results indicate that the 'reactive' thiol group of the enzyme is required for the conformational changes associated with formation of a 'transition-state analogue' complex.
在一系列保留不同酶活性水平的兔肌肉肌酸激酶硫醇修饰衍生物中,研究了底物和配体诱导的构象变化。结果表明,与“过渡态类似物”复合物形成相关的构象变化需要酶的“活性”硫醇基团。
