Cysteine is a uniquely reactive amino acid, capable of undergoing both nucleophlilic and oxidative post-translational modifications. One such oxidation reaction involves the covalent modification of cysteine via the gaseous second messenger nitric oxide (NO), termed S-nitrosylation (SNO). This dynamic post-translational modification is involved in the redox regulation of proteins across all phylogenic kingdoms. In mammals, calcium-dependent activation of nitric oxide synthase triggers the local release of nitric oxide, which activates nearby guanylyl cyclases and cGMP-dependent pathways. In parallel, diffusible nitric oxide can locally modify redox active cellular thiols, functionally modulating many redox sensitive enzymes. Aberrant S-nitrosylation is implicated in the pathology of many diseases, including neurodegeneration, inflammation, and stroke. In this review, we discuss current methods to label sites of S-nitrosylation for biochemical analysis. The most popular method involves a series of biochemical steps to mask free thiols followed by selective nitrosothiol reduction and capture. Other emerging methods include mechanism-based phosphine probes and mercury enrichment chemistry. By bridging new enrichment approaches with high-resolution mass spectrometry, large-scale analysis of protein nitrosylation has highlighted new pathways of oxidative regulation.
