Abstract

Disclosed herein is a cell containing a modified peptide. More specifically, the N-terminal amino acid residue of the peptide is modified by the addition of an aryl ketone group which, when contacted with an appropriate substrate, and exposed to light having a wavelength of about 330 nm or greater, results in the covalent bonding of the peptide to the substrate by a C--H insertion dominant mechanism. In preferred, embodiments, the aryl ketone is a benzophenone moiety. The peptide can be designed to specifically bind to a protein of interest in the cell. The cell is then contacted with light having a wavelength of greater than about 330 nm to bind the peptide covalently to the binding site on the intracellular protein of interest. In this way, the modified peptide can be used to specifically and irreversibly block a binding site on an intracellular protein of interest.
