This review will discuss some recent work describing the role of Ser/Thr phosphorylation as a post-translational mechanism of regulation in bacteria. I will discuss the interaction between bacterial eukaryotic-like Ser/Thr kinases (eSTKs) and two-component systems as well as hints as to physiological function of eSTKs and their cognate eukaryotic-like phosphatases (eSTPs). In particular, I will highlight the role of eSTKs and eSTPs in the regulation of peptidoglycan metabolism and protein synthesis. In addition, I will discuss how data from phosphoproteomic surveys suggest that Ser/Thr phosphorylation plays a much more significant physiological role than would be predicted simply based on in vivo and in vitro analyses of individual kinases.
本综述将讨论一些近期的研究工作,这些工作描述了丝氨酸/苏氨酸磷酸化作为细菌中一种翻译后调控机制的作用。我将讨论细菌类真核丝氨酸/苏氨酸激酶(eSTK)与双组分系统之间的相互作用,以及关于eSTK及其同源类真核磷酸酶(eSTP)生理功能的线索。特别地,我将强调eSTK和eSTP在肽聚糖代谢和蛋白质合成调控中的作用。此外,我将讨论磷酸化蛋白质组学调查的数据如何表明,丝氨酸/苏氨酸磷酸化所起的生理作用比仅基于对单个激酶的体内和体外分析所预测的要重要得多。
