Abstract

The 3'-CCA end of tRNA(Phe) from E. coli and Thermus thermophilus was modified by stepwise degradation and ligation of the shortened tRNA with different trinucleotides (pUpUpA, (pA)3, (pC)3, (pU)3). Kinetic parameters for the aminoacylation reaction of modified tRNAs have been determined. The role of the 3'-terminal trinucleotide of tRNA(Phe) in tRNA binding and aminoacylation by phenylalanyl-tRNA synthetases from E. coli and Thermus thermophilus is postulated.
