چکیده

Mutation of the Arabidopsis thaliana tRNA (Trp)(CCA) anticodon or of the A73 discriminator base greatly diminishes in vitro aminoacylation with tryptophan, indicating the importance of these nucleotides for recognition by the plant tryptophanyl-tRNA synthetase. Mutation of the tRNA (Trp)(CCA) anticodon to CUA so as to translate amber nonsense codons permits tRNA (Trp)(CCA) to be aminoacylated by A.thaliana lysyl-tRNA synthetase. Thus, translational suppression by tRNA (TRP)(CCA) observed in plant cells includes significant incorporation of lysine into protein.

Identity elements for the aminoacylation of metazoan mitochondrial tRNAArg have been widely conserved throughout evolution and ensure the fidelity of the AGR codon reassignment

Eumetazoan mitochondrial tRNAs possess structures (identity elements) that require the specific recognition by their cognate nuclear-encoded aminoacyl-tRNA synthetases. The AGA (arginine) codon of the standard genetic code has been reassigned to serine/glycine/termination in eumetazoan organelles and is translated in some organisms by a mitochondrially encoded tRNA(Ser)UCU. One mechanism to pre...

Two conformations of a crystalline human tRNA synthetase-tRNA complex: implications for protein synthesis.

Aminoacylation of tRNA is the first step of protein synthesis. Here, we report the co-crystal structure of human tryptophanyl-tRNA synthetase and tRNATrp. This enzyme is reported to interact directly with elongation factor 1alpha, which carries charged tRNA to the ribosome. Crystals were generated from a 50/50% mixture of charged and uncharged tRNATrp. These crystals captured two conformations ...

Competition of aminoacyl-tRNA synthetases for tRNA ensures the accuracy of aminoacylation.

The accuracy of protein biosynthesis rests on the high fidelity with which aminoacyl-tRNA synthetases discriminate between tRNAs. Correct aminoacylation depends not only on identity elements (nucleotides in certain positions) in tRNA (1), but also on competition between different synthetases for a given tRNA (2). Here we describe in vivo and in vitro experiments which demonstrate how variations...

Identity elements of tRNA(Thr) towards Saccharomyces cerevisiae threonyl-tRNA synthetase.

Identity elements of tRNA(Thr) towards Saccharomyces cerevisiae threonyl-tRNA synthetase were examined using in vitro transcripts. By mutation studies, a marked decrease in aminoacylation with threonine showed that the first base pair in the acceptor stem and the second and third positions of the anticodon are major identity elements of tRNA(Thr), which are essentially the same as those of Esch...

Structural requirements for binding of bovine tRNATrp with avian myeloblastosis virus DNA polymerase

Avian DNA polymerases use host tRNATrp as the primer for transcription. Bovine tRNATrp has been previously shown to be a biologic substitute for the avian primer. A bovine tRNATrp fragment has been identified as having a high binding affinity for the polymerase. The fragment is assigned to be 67 nucleotides, and contains most of the elements required to maintain the secondary and tertiary struc...
