[Abstract]  Post-translational protein modifications (PTMs) orchestrate the activity of individual proteins and ensure their proper function. While modifications such as phosphorylation or glycosylation are well understood, more unusual modifications, including nitrosylation or AMPylation remain comparatively poorly characterized. Research on protein AMPylation–which refers to the covalent addition of an AMP moiety to the side chains of serine, threonine or tyrosine–has undergone a renaissance (Yarbrough et al., 2009; Engel et al., 2012; Ham et al., 2014; Woolery et al., ... [摘要]  翻译后蛋白质修饰(PTM)协调各种蛋白质的活性并确保其功能正常。虽然诸如磷酸化或糖基化的修饰被很好地理解,但是更不寻常的修饰,包括亚硝基化或AMP化仍然比较差的表征。关于蛋白质AMP化的研究 - 其是将AMP部分共价加成到丝氨酸,苏氨酸或酪氨酸的侧链,已经经历了复兴(Yarbrough et al。,2009; Engel et al。 2012年; Ham等人,2014年; Woolery等人,2014年; Preissler等人,2015年; ; Sanyal等人,2015; Truttmann等人,2016; Truttmann等人,2017)。鉴定和表征含丝状(fic)结构域的AMPylases引起了对该PTM的新兴趣(Kinch等人,2009; Yarbrough等人,2009)。基于最近的体内和体外研究,我们现在知道分泌的细菌AMPylase共价连接AMP到Rho家族GTP酶的成员,而后生动物AMPylases修饰HSP70家族蛋白在细胞质和内质网(ER)(Itzen等人,2011; Hedberg和Itzen,2015; Truttmann和Ploegh,2017)。认为AMP化学将HSP70置于不能参与蛋白质重折叠反应的引发剂但瞬时失活的状态(Preissler等人,2015)。 ...
