  可逆抑制剂以可被ClpX协会撤销的确定构象状态逮捕ClpP

  摘要：

  酪蛋白水解蛋白酶P（ClpP）是金黄色葡萄球菌发病机理的重要调节剂。对ClpP肽酶活性抑制剂的高通量筛选导致鉴定出该酶类别的第一个非共价结合物。小分子与金黄色葡萄球菌ClpP的共结晶揭示了一种新颖的结合模式：由于保守残基脯氨酸125的旋转，ClpP被锁定在确定的构象状态，这导致催化三联体的扭曲并抑制了三聚体。肽酶活性。基于这些结构见解，通过合理的设计和虚拟筛选对分子进行了优化，从而使衍生物的效力超过了以前的ClpP抑制剂。令人惊讶的是，构象锁被ClpX的绑定所推翻，一种相关的分子伴侣，可通过ClpXP复合物中的底物展开来进行蛋白水解。因此，通过相关的伴侣蛋白调节抑制剂结合是对于ClpP药物开发重要的出乎意料的机制。
