Application

CA-nitrile is a negative control probe that can be used for labeling cysteines through alkylation but lacks an alkyne necessary for labeling. A method was developed using cysteine-reactive compounds including this one to allow for unbiased analysis of proteomic data in quantitave applications (Zanon et al. 2021). The method uses light or heavy labeling with the isotopically labelled desthiobiotin azide (isoDTB) tag for mass spectrometry analysis (Zanon et al. 2020). Analysis then uses the isotopic tandem orthogonal proteolysis activity-based protein profiling (isoTOP-ABPP) workflow (Weerapana et al. 2010, Backus et al. 2016).

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

Small molecules are powerful tools for investigating protein function and can serve as leads for new therapeutics. Most human proteins, however, lack small-molecule ligands, and entire protein classes are considered 'undruggable'. Fragment-based ligand discovery can identify small-molecule probes for proteins
