Application
ArVS-alkyne is a Michael acceptor probe that can be used to label cysteines. A method was developed using cysteine-reactive compounds including this one to allow for unbiased analysis of proteomic data in quantitative applications . The method uses light or heavy labeling with the isotopically labelled desthiobiotin azide (isoDTB) tag for mass spectrometry analysis . Analysis then uses the isotopic tandem orthogonal proteolysis activity-based protein profiling (isoTOP-ABPP) workflow.

Rapid development of bacterial resistance has led to an urgent need to find new druggable targets for antibiotics. In this context, residue-specific chemoproteomic approaches enable proteome-wide identification of binding sites for covalent inhibitors. Described here are easily synthesized isotopically labeled

Cysteine is the most intrinsically nucleophilic amino acid in proteins, where its reactivity is tuned to perform diverse biochemical functions. The absence of a consensus sequence that defines functional cysteines in proteins has hindered their discovery and characterization. Here we
