Aspartate identity of transfer RNAs

Biochimie, 1996
Structure/function relationships accounting for specific tRNA charging by class II aspartyl-tRNA synthetases from Saccharomyces cerevisiae, Escherichia coli and Thermus thermophilus are reviewed. Effects directly linked to tRNA features are emphasized and aspects about synthetase contribution in expression of tRNA(Asp) identity are also covered.

Aminoacy1 Transfer RNA Formation. VI. Binding of Cations to Transfer RNA and Its Role in Aminoacy1 Transfer RNA Formation1

The Journal of Biochemistry, 1976
The role of cations (polyamines and Mg2+) in isoleucyl-tRNA formation catalyzed by purified isolecuyl-tRNA synthetase [EC 6.1.1.5] from Escherichia coli was studied. It was found that spermine, spermidine, and Mg2+ bind to tRNA and that when bound to these cations, tRNA acts as substrate of aminoacylation without requiring further cations.

Nucleotide Sequence and Function of Transfer RNA and Precursor Transfer RNA

1973
At present, we have to consider the functional interactions of the tRNA molecule without knowing its three-dimensional structure. Comparison of tRNA sequences has shown that they have a common hydrogen-bonded structure defined by the cloverleaf arrangement, and in addition they have certain common sequences or correlated sequences which may also be ...

Studies on transfer RNAs

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972
Abstract 1. 1. Treatment of tRNA fMet with hydroxylamine caused specific modification of cytosine residues among a number of constituent nucleobases and only three out of the 26 cytosine residues in the tRNA were modified. The modified tRNA was found to charge methionine up to 64 % of its original acceptance. 2. 2.

On the origin of the transfer RNA molecule

Journal of Theoretical Biology, 1992
Data and arguments are given in favour of the hypothesis that the primitive tRNA molecule may have originated from a direct duplication event involving one of the two halves of the tRNA molecule. It seems that a molecule capable of assuming a hairpin structure was involved as a precursor in this duplication.

Studies on transfer RNA and transfer RNA genes in Drosophila melanogaster

1977
In the present study Drosophila melanogaster was used to define the organization and expression of tRNA genes. The three major Drosophila valine tRNAs were isolated and purified by standard chromatographic techniques. Nucleoside analysis indicated that of these tRNAs only tRNA₄Val contained inosine.
