在最近一期的《结构》杂志上,考德威尔等人(1999)发表了一篇关于结构的文章。(2016)确定了APH(2″)-Ia与氨基糖苷和核苷的各种组合的复合物的晶体结构,这令人信服地揭示了这种抗性酶的催化活性受到GTP三磷酸的构象变化的调节,这是一种以前未知的抗生素激酶机制。
In a recent issue ofStructure, Caldwell et al. (2016) determined crystal structures of APH(2″)-Ia in complex with various combinations of aminoglycosides and nucleosides, which compellingly revealed that the catalytic activity of this resistance enzyme is regulated by a conformational change of the triphosphate of GTP, a mechanism previously unknown for antibiotic kinases.
