Electrophilic groups that undergo sulfur-exchange chemistry with protein nucleophiles can serve as the functional basis of chemical proteomic probes. A new addition to this class, sulfuramidimidoyl fluoride (SAF), which can be included in an array of covalent small molecule probes, exhibits a unique reactivity profile with proteins.
