ABSTRACT
Modifications of cysteine residues in redox-sensitive proteins are key to redox signaling and stress response in all organisms. A novel type of redox switch was recently discovered that comprises lysine and cysteine residues covalently linked by an nitrogen-oxygen-sulfur (NOS) bridge. Here, we discuss chemical and biological implications of this discovery.
