Supplementary Material

By using binuclear TbIII complexes, phosphorylation of tyrosine in peptides by protein tyrosine kinases (PTKs) and dephosphorylation by protein tyrosine phosphatases (PTPs) can be successfully visualized in a real-time fashion. The activities of various inhibitors on these enzymes are quantitatively evaluated, indicating a strong potential of the method to efficient screening of eminent inhibitors from a number of candidates.
