Transfer RNA (tRNA) from all organisms on this planet contains modified nucleosides, which are derivatives of the four major nucleosides. tRNA from Escherichia coli/Salmonella enterica contains 31 different modified nucleosides, which are all, except for one (Queuosine[Q]), synthesized on an oligonucleotide ...

Origins of Life, 1984
Phylogenetic trees of transfer RNA specific for phenylalanine, methionine initiator glycine and valine are constructed. Although the exact relationships between taxa cannot be obtained from the mere analysis of the sequences some conclusions can be drawn about the evolution of this molecule.

Crystallization of Transfer RNA
Nature, 1968A bacterial transfer RNA (tRNAFMet) has been obtained in micro-crystalline form. Its probable unit cell dimensions have been deduced from X-ray powder photographs.

Journal of Molecular Biology, 1973
Abstract Evolution by gene duplication and subsequent divergence is indicated by similarities common to 43 different transfer RNAs. Pairwise comparisons of these tRNAs reveal additional similarity, greatest for certain pairs of tRNAs for the same amino acid in the same organism, and also occurring in certain pairs of tRNAs for different amino acids ...

Transfer RNAs and transfer RNA-derived small RNAs in cerebrovascular diseases
Experimental NeurologyThis article explores the important functions of transfer RNA and - transfer RNA derived small RNAs (tsRNAs) in cellular processes and disease pathogenesis, with a particular emphasis on their involvement in cerebrovascular disorders. It discusses the biogenesis and structure of tsRNAs, including types such as tRNA halves and tRNA-derived fragments ...

Annual Review of Genetics, 1972
Initially the only way of identifying tRNA genes was by DNA-RNA hy bridization. The discovery that informational suppression may result from muta tions in tRNA genes has not only allowed their genetic analysis but has led to the isolation of mutants important in understanding the function, structure, and synthesis of tRNA.

1. Altered column-chromatographic profiles of a number of hepatoma and other tumor aminoacyl-tRNAs have been observed, most frequently for tRNAPhe, tRNAAsp, tRNAAsn, tRNATyr, tRNAHis, and tRNASer. 2. The chemical basis for the chromatographic alterations is still obscure, except that a tRNAPhe in Morris hepatoma 7777, which is not ...

Transfer RNA nucleotidyltransferase repairs all transfer RNAs randomly
Journal of Molecular Biology, 1977Total Escherichia coli transfer RNA was converted to tRNA-C-C by periodate oxidation and partially repaired with either E. coli or rabbit liver tRNA nucleotidyltransferase. Aminoacylation of the partially repaired molecules indicated that individual tRNA species were each repaired to the same extent as the total population of molecules.

Mitochondrial transfer RNAs in yeast: identification of isoaccepting transfer RNAs
Biochemistry, 1978To delineate the total number of tRNAs encoded by yeast mitochondrial DNA (mtDNA), we have examined mitochondrial tRNA preparations for the presence of heterogenic isoaccepting tRNAs. Analyses of /sup 3/H-labeled aminoacylated mitochondrial tRNAs by reversed-phase column chromatography (RPC-5) coupled with hybridization to mtDNA detected only one major

Transfer RNA in RNA Tumor Viruses
1977Publisher Summary This chapter reviews that the presence of the majority of the tRNAs inside an RNA tumor virus remains an enigma. The finding that specific tRNA molecules can serve as primers for DNA synthesis is of fundamental importance in the field of molecular biology.
