β-Lactam resistance in limits treatment options. Stp1 and Stk1, a serine-threonine phosphatase and kinase, respectively, mediate serine-threonine kinase (STK) signaling. Loss-of-function point mutations in were detected among laboratory-passaged β-lactam-resistant strains lacking and , the major determinants of β-lactam resistance in the bacteria. Loss of Stp1 function facilitates β-lactam resistance of the bacteria.
β-内酰胺耐药限制了治疗选择。Stp1 和 Stk1 分别是一种丝氨酸-苏氨酸磷酸酶和激酶，介导丝氨酸-苏氨酸激酶 (STK) 信号转导。在缺乏细菌中主要的β-内酰胺耐药决定因子 blaNDM-1 和 blaCTX-M-15 的实验室传代β-内酰胺耐药株中检测到 点突变。Stp1 功能丧失促进了细菌的β-内酰胺耐药性。
