A light switch for phosphotyrosine- recognizing proteins: Irradiation of the bioisosteric benzoylphosphonate suffices to “turn off” the activity of target proteins and to label them covalently (see scheme). Photoactive bioisosters may find applications in functional cell biology, bioanalytics, and proteome research.
