Application
HMP-alkyne is a probe that can be used to photochemically label tryptophans. A method was developed using cysteine-reactive compounds including this one to allow for unbiased analysis of proteomic data in quantitative 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)

The biotin-tagged electrophiles 1-biotinamido-4-(4'-[maleimidoethylcyclohexane]-carboxamido)butane (BMCC) and N-iodoacetyl-N-biotinylhexylenediamine (IAB) have been used as model electrophile probes in complex proteomes to identify protein targets associated with chemical toxicity. Whereas IAB activates stress signaling and apoptosis in HEK293 cells, BMCC does not. Cysteine
