由细胞氧化水平升高引起的蛋白质的氧化翻译后修饰在生理和病理生理过程中起重要作用。由于方法学的进步使得检测、量化和鉴定细胞和组织中的这种变化成为可能,对蛋白质氧化还原状态变化的评估越来越普遍。这篇综述概述了生化方法,这些方法可用于监测蛋白质硫醇发生的一系列不同的氧化和亲电修饰,这些修饰在氧化剂对生物系统的调节或不适应影响中很重要。讨论的几种方法对于监测已建立的氧化还原传感蛋白(如Keap1)的氧化还原状态是有价值的。
Oxidative post-translational modifications of proteins resulting from events that increase cellular oxidant levels play important roles in physiological and pathophysiological processes. Evaluation of alterations to protein redox states is increasingly common place because of methodological advances that have enabled detection, quantification and identification of such changes in cells and tissues. This mini-review provides a synopsis of biochemical methods that can be utilized to monitor the array of different oxidative and electrophilic modifications that can occur to protein thiols and can be important in the regulatory or maladaptive impact oxidants can have on biological systems. Several of the methods discussed are valuable for monitoring the redox state of established redox sensing proteins such as Keap1.
