WebS-nitrosylation (or S-nitrosation, SNO) is an oxidative posttranslational modification to the thiol group of a cysteine amino acid residue. There are several methods to detect SNO modifications, mostly based on the classic biotin-switch assay, where the labile SNO sites are replaced with a stable biotin moiety to facilitate enrichment of the modified proteins. WebThe assay is a variation of the modified biotin switch assay. The reaction mixture is treated with the thiol blocking reagent (BR): methylsulfonyl benzothiazole (MSBT), followed by treatment with a methylcyanoacetate (MCA) derivative that comprises a nucleophilic component and a biotin moiety as a reporter.
WebThe standard biotin switch assay was used to reveal the presence of NO-induced modifications in GSNO-treated HPAEC lysates (Fig. 2A). Silver stain gel analysis shows a clear increase in the amount of protein labeled following GSNO treatment when compared with the untreated, GSH or GSSG treated samples ( n = 3), indicating these proteins are ...
