Anion Sensor-Based Ratiometric Peptide Probe for Protein Kinase Activity
摘要:
A new fluorescent sensor consisting of Cd-II-cylcen appended aminocoumarin and a substrate peptide for protein kinase A (PKA) has been designed. Upon phosphorylation by PKA, the metal complex moiety binds to a phosphorylated residue, which in turn displaces the coumarin fluorophore, and this event results in ratiometric change of excitation spectrum in neutral aqueous solution.

Heterobifunctionalfluorescent reagents of coumarin type are synthesized. They possess, in position 7, a rigidized or un-rigidized amino group and, in position 3 or 4, a carboxylic function. The fluorescence characteristics of these compounds are described and compared with the 7-amino-4-methylcoumarin. The influence of the relative freedom of rotation of the amino group or the position of the acid
