蛋白质AMP化-使用ATP作为供体将腺苷5 '-单磷酸(AMP)残基共价连接到氨基酸侧链-是一种翻译后修饰,越来越多地被认为与正常和病理细胞信号传导相关。在后生动物中,单拷贝的含fic结构域的AMP酶(负责AMP化的酶)优先修饰一组专用靶标,并有助于感知细胞应激及其调节。病原菌可以利用真核靶蛋白的AMP化来重新连接宿主细胞信号传导机制,以支持其繁殖和存活。本文综述了后生动物中内源性和寄生性蛋白的AMP化,并总结了目前关于含Fic结构域的AMP酶如何促进细胞蛋白质稳态的观点。
Protein AMPylation – the covalent attachment of an adenosine 5’-monophosphate (AMP) residue to amino acid side chains using ATP as the donor – is a post-translational modification increasingly appreciated as relevant for both normal and pathological cell signaling. In metazoans, single copies of fic-domain-containing AMPylases, the enzymes responsible for AMPylation, preferentially modify a set of dedicated targets and contribute to the perception of cellular stress and its regulation. Pathogenic bacteria can exploit AMPylation of eukaryotic target proteins to rewire host cell signaling machinery in support of their propagation and survival. We review endogenous as well as parasitic protein AMPylation in metazoans and summarize current views of how Fic-domain containing AMPylases contribute to cellular proteostasis.
