The comprehensive identification of ATP-binding proteins, such as the important class of kinases, and the dynamic analysis of nucleotide-protein interactions at the proteomic scale are fundamental for better understanding of the regulatory mechanisms of nucleotide-binding proteins.
ATP binding activities as well as specific binding sites of proteins can be detected globally in any biological sample or tissue from any species by using Biotin/Desthiobiotin-conjugated acyl-ATP probes (AcATP)[2-6].
