NO2-alkyne is a linear C-nucleophile based chemoselective probe for detecting sulfenylated proteins.
Highlights:
Mild oxidation can convert the sulfhydryl group of cysteine residues on proteins to cysteine-sulfenic acid derivatives (Cys-SOH). Protein sulfenylation is a post-translational modification that is relevant to redox signaling. NO2-alkyne shows more than 40-fold enhanced reactivity (compared to dimedone) towards a peptide based small molecule sulfenic acid model.
