组蛋白的翻译后修饰引起染色质内的结构和功能变化,从而调节各种表观遗传过程。表观遗传机制依赖于酶,其活性由辅酶和中间代谢产物驱动。赖氨酸乙酰基转移酶(KAT)催化乙酰基从乙酰辅酶A转移到精氨酸基团。这种关键代谢物的利用表明这些酶受到细胞代谢状态的调节。这篇综述强调了将KAT与代谢联系起来的研究。我们涵盖了新发现的酰基修饰(丙酰化和丁酰化),讨论了细胞乙酰辅酶A水平对KAT活性的控制,并提供了乙酰化如何调节代谢蛋白质的见解。最后,我们总结了目前的方法来确定新的KAT及其代谢底物的讨论。
Post-translational modifications of histones elicit structural and functional changes within chromatin that regulate various epigenetic processes. Epigenetic mechanisms rely on enzymes whose activities are driven by co-enzymes and metabolites from intermediary metabolism. Lysine acetyltransferases (KATs) catalyze the transfer of acetyl groups from acetyl-CoA to epsilon amine groups. Utilization of this critical metabolite suggests these enzymes are modulated by the metabolic status of the cell. This review highlights studies linking KATs to metabolism. We cover newly identified acyl-modifications (propionylation and butyrylation), discuss the control of KAT activity by cellular acetyl-CoA levels, and provide insights into how acetylation regulates metabolic proteins. Lastly, we conclude with a discussion of the current approaches for identifying novel KATs and their metabolic substrates.
