We have determined a 1.18 Å resolution X-ray crystal structure of a novel ruthenocenyle-6-aminopenicillinic acid in complex with CTX-M β-lactamase, showing unprecedented details of interactions between ruthenocene and protein. As the first product complex with an intact catalytic serine, the structure also offers insights into β-lactamase catalysis and inhibitor design.
我们已经确定了一种新型钌茂烯基-6-氨基青霉烷酸与CTX-Mβ-内酰胺酶复合物的X射线晶体结构,分辨率为1.18Å,展示了钌茂烯与蛋白质之间前所未有的相互作用细节。作为第一个与完整催化丝氨酸形成的产物复合物,该结构还为β-内酰胺酶催化和抑制剂设计提供了见解。
