Understanding its pleiotropic effects requires a deep analysis of the molecular mechanisms underlying its mode of action. In the recent years, efforts have been made in the identification of plant proteins modified by NO at the post-translational level, notably by S-nitrosylation. This reversible process involves the formation of a covalent bond between NO and reactive cysteine residues. This research has now born fruits and numerous proteins regulated by S-nitrosylation have been identified and characterized. This review describes the basic principle of S-nitrosylation as well as the Biotin Switch Technique and its recent adaptations allowing the identification of S-nitrosylated proteins in physiological contexts. The impact of S-nitrosylation on the structure/function of selected proteins is further discussed. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
