摘要: A specific illumination approach has been developed for identification of adenosine triphosphate (ATP)-binding proteins. This strategy utilizes a tandem photoactivatable unit that consists diazirine group as carbene precursor and an o-hydroxycinnamate moiety coumarin precursor. The photolysis induces cross-link on target proteins is followed by photoactivation generation with concomitant release the pre-installed affinity ligand. ATP, installed this cross-linker at γ-position, successfully transferred onto ATP-binding using only UV-irradiation.
