應用

EBX2-alkyne is a hypervalent iodine reagent used for labeling 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
