Oxidoreduction of Protein Thiols in Redox Regulation

Biochem Soc Trans. 2005 Dec;33(Pt 6):1378-81. doi: 10.1042/BST20051378.


Protein cysteines can undergo various forms of oxidation, some of them reversible (disulphide formation, glutathionylation and S-nitrosylation). While in the past these were viewed as protein damage in the context of oxidative stress, there is growing interest in oxidoreduction of protein thiols/disulphides as a regulatory mechanism. This review discusses the evolution of the concept of redox regulation from that of oxidative stress and the redox state of protein cysteines in different cellular compartments.
