翻译后修饰(PTMs)改变了蛋白质的结构、功能和定位,在生理和病理生理条件中起着关键作用。许多ptm产生于内源性代谢中间体,并作为代谢反馈的传感器来维持细胞生长和体内平衡。PTMs的一个关键特征是它们的生化发生,可以通过非酶内聚(nPTMs)或酶催化反应(ePTMs)产生。ptm的丰度和位点特异性是由专门的酶类决定的,这些酶添加(写入)或去除(擦除)化学添加物。在这篇综述中,我们将重点介绍已经鉴定的700多个PTMs中的一些的生化发生和调控。
Post-translational modifications (PTMs) alter protein structure, function, and localization and play a pivotal role in physiological and pathophysiological conditions. Many PTMs arise from endogenous metabolic intermediates and serve as sensors for metabolic feedback to maintain cell growth and homeostasis. A key feature to PTMs is their biochemical genesis, which can result from either non-enzymatic adduction (nPTMs) or through enzyme-catalyzed reactions (ePTMs). The abundance and site-specificity of PTMs are determined by dedicated classes of enzymes that add (writers) or remove (erasers) the chemical addition. In this review we will highlight the biochemical genesis and regulation of a few of the 700+ PTMs that have been identified.
