Compositions including orthogonal aminoacyl-tRNA synthetases (O-RS) that preferentially aminoacylate an orthogonal tRNA (O-tRNA) with trifluoromethoxyphenylalanine are provided. Nucleic acids encoding these aminoacyl-tRNA synthetases are also provided.

UV-cleavage of the nitrobenzyl-photocage from oNBTyr re-established binding. These data suggest not onlyrobust methods for using unnatural amino acids to study large proteins by NMR but also establish a new avenue for the site-specific labeling of proteins at individual residues without altering the protein sequence, a feat that can currently not be accomplished with any other method.
