ABSTRACT

A photo-switchable fluorescent flagging approach has been developed to identify photoaffinity-labeled peptides in target protein. Upon photochemical release of the ligand, the protein was newly modified with a coumarin in place of the previously attached biotin. It allowed us to simplify complex identification processes for labeled sites.
