Abstract

A genetically encoded precursor to an aryl nitrene, para-azidophenylalanine, was introduced site specifically into proteins to deduce if distinct environments were capable of caging a reactive organic intermediate. Following photolysis of mutant T4 lysozyme or green fluorescent proteins, EPR spectra showed, respectively, the presence of a triplet nitrene and an anilino radical.
