Abstract
Protein S-nitrosation is an important post-translational modification. However, the detection of S-nitrosation is still problematic because S-nitrosation products, that is, S-nitrosothiols, are unstable species. Here a new reaction which can selectively convert unstable S-nitrosothiols to stable thioethers in one-pot under very mild conditions is reported. This reaction has the potential to be applied in the detection of protein S-nitrosation.
