摘要

磷酸泛硫乙烯基转移酶通过连接辅酶 A 衍生的磷酸泛硫乙烯基连接体来激活载体蛋白。本研究介绍了一种通过带有炔基的改性 HSCoA 监控这一过程的方法，该方法允许铜催化的炔吖啶环加成荧光标签。在酶筛选中应用这种方法，发现了新的杂合 PPT 酶。

A clickable coenzyme A derived probe for investigating phosphopantetheinyl transferase activity in natural product biosynthesis†

Phosphopantetheinyl transferases activate carrier proteins through attachment of a coenzyme A derived phosphopantetheinyl linker. This study describes a method to monitor this process through a modified HSCoA with an alkyne group, allowing for the Cu-catalysed alkyne–azide cycloaddition of a fluorescent tag. Application of the method in an enzyme screening resulted in the identification of new promiscuous PPTases.
