The first example of a photoactivated probe of intracellular enzymatic activity is described. The caged derivative of a fluorescent protein kinase C peptide-based sensor was prepared by modifying the free hydroxyl group of a phosphorylatable serine moiety with a photolabile appendage that blocks phosphoryl transfer. We have demonstrated that the caged sensor allows one to (1) sample PKC activity with exquisite temporal precision,(2) control the ...
