Abstract:
"Induced hydrolysis" a new hydrolytic activity, was found by measuring AMP-production during aminoacylation of tRNAPhe-CCA by yeast phenylalanyl-tRNA synthetase in the presence of tRNAPhe-CC under conditions of low ionic strength at pH 8.5. Experiments using the elongation factor Tu . GTP provide evidence that transfer of phenylalanine to the tRNAPhe-CCA is followed by rapid hydrolysis in the presence of tRNAPhe-CC. A simple mechanism shows good agreement with the experimental data.
