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(More)
Coupling the activities of normally disparate proteins into one functional unit has significant potential in terms of constructing novel switching components for synthetic biology or as biosensors. It also provides a means of investigating the basis behind transmission of conformation events between remote sites that is integral to many biological(More)
There are many approaches to introduce non-native functionality into proteins either translationally or post-translationally. When a noncanonical amino acid (NAA) is incorporated translationally, the host organism's existing translational machinery is relied upon to insert the amino acid by the same well-established mechanisms used by the host to achieve(More)
