| 1 | The functional roles of phenylalanine and ATP in productive binding of the tRNA(Phe) acceptor end have been studied by photoaffinity labeling (cross-linking) of T. thermophilus phenylalanyl-tRNA synthetase (PheRS) with tRNA(Phe) analogs containing the s(4)U residue in different positions of the 3"-terminal single-stranded sequence. | Phenylalanine | mitochondrially encoded tRNA glycine | Homo sapiens |
| 2 | Phenylalanine affects the positioning of the base and ribose moieties of the 76th nucleotide, and the recorded effects do not depend on structural differences between bacterial and eukaryotic tRNA(Phe)s. Both in the absence and presence of phenylalanine, ATP more effectively inhibits the PheRS labeling with the s(4)U76-substituted analog of human tRNA(Phe) (tRNA(Phe)-s(4)U76) than with E. coli tRNA(Phe)-s(4)U76: in the first case the labeling of the alpha-subunits is inhibited more effectively; the labeling of the beta-subunits is inhibited in the first case and increased in the second case. | Phenylalanine | mitochondrially encoded tRNA glycine | Homo sapiens |
