affairs: Phosphoester substrates that release electrophilic quinone‐methides were applied as activity‐based probes in three phosphotriesterases that differ in mechanism and level of activity. Their substrates′ reactivity, and mode of labeling, were systematically investigated with the aim of achieving specific cis labeling rather than trans.
内部事务:释放亲电子醌甲基化物的磷酸酯底物被用作三种不同机制和活性水平的磷酸三酯酶中的基于活性的探针。系统地研究了它们的底物反应性和标记模式,目的是实现特定的顺式标记而不是反式标记。
