Aminoacyl-tRNA analogues; synthesis, purification and properties of 3'-anthraniloyl oligoribonucleotides.
Reaction of isatoic anhydride with adenosine, adenosine 5'-phosphate, oligoribonucleotides or with the E. coli tRNAVal led to attachment of an anthraniloyl residue at 2'- or 3'-OH groups of 3'-terminal ribose residue. No protection of the 5'-hydroxyl group or internal 2'-hydroxyl groups is required for this specific reaction. Anthraniloyl-tRNA which is an analogue of aminoacyl-tRNA forms a ternary complex with EF-Tu*GTP. The anthraniloyl-residue is used as a fluorescent reporter group to monitor interactions with proteins.
