Controlled S-nitrosation
&
Abstract
Nitrosation of thiol groups on peptides and proteins has emerged as a major mechanism of cellular signaling and has been the subject of numerous recent articles and reviews. Although evidence for S-nitrosation (the nitric oxide (NO) adduct with cysteine) is unequivocal in vivo, the missing link has been the question of whether S-nitrosation is a random, nonselective process or whether it is directed to specific sites on specific proteins like other post-translational modifications.
