AbstractPhenylalanyl-tRNA synthetase from the extreme thermophilic bacterium Thermus thermophilus can incorporate more than one molecule of phenylalanine into the tRNAPhe. It is shown that the ‘hyperaminoncylated’ tRNAPPhe is the bis-2′,3′-O-phenylalanyl-tRNAPhe, and its formation is typical for the thermophilic enzyme but does not occur for E. coli phenylalanyl-tRNA synthetase under the same conditions
