Webnoncognate tRNAs via the use of chimeric tRNAs, we have discovered a second recognition site for the E. coliTGT in the TCC arm of in vitro-transcribed yeast tRNAPhe. Kinetic analyses of synthetic mutant oligoribonucleotides corresponding to the TCC arm of the yeast tRNAPhe indicate that the specific site of TGT action is G53 (within a U-G-U WebA chimeric tRNA with the human acceptor stem and other sequences from the yeast molecule acts similarly to the human tRNASer. The 3:70 base pair in the acceptor stem (C:G in yeast and A:U in humans) is a prime determinant of the specificity.
