The nucleotide sequence of the 5S ribosomal RNA from a photobacterium

Journal of Molecular Evolution, 1975
Comparative sequencing studies provide powerful insights into molecular function and evolution. The sequence for 5S ribosomal RNA from Photobacter strain 8265 is eighteen base replacements removed from that of Escherichia coli. Of these, the vast majority involve a G or C becoming an A or U.

Alternative conformers of 5S ribosomal RNA and their biological relevance

Biochemistry, 1985
Different conformational states of Escherichia coli 5S ribosomal RNA that may participate in protein biosynthesis have been either detected experimentally or predicted on the basis of phylogenetic sequence comparisons. The A conformer exists in a high-salt form (AH) that binds ribosomal proteins and assembles into the 50S subunit and in a low-salt form

[49] Primer-directed deletions in 5S ribosomal RNA

1988
Publisher Summary This chapter presents detailed procedure for generating and characterizing deletion mutants in Escherichia coli 5S RNA. There follows a more detailed appraisal of the 5S RNA expression system in plasmids, deletion repair mechanisms in the cell, the possible occurrence of DNA rearrangements, and methods for determining structural ...

Location of the genes for 5S ribosomal RNA in Xenopus laevis

Chromosoma, 1973
In situ hybridization of 5S RNA and cRNA transcribed in vitro from Xenopus laevis 5S DNA shows that 5S DNA is localized at or near the telomere region of the long arm of many, if not all, of the X. laevis chromosomes. No 5S DNA is detected near the nucleolus organizer in the normal X. laevis chromosome complement, but in a X.

Developmental regulation of two 5S ribosomal RNA genes.

Science, 1988
The developmental regulation of two kinds of Xenopus 5S RNA genes (oocyte and somatic types) can be explained by differences in the stability of protein-protein and protein-DNA interactions in a transcription complex that directs transcription initiation

Accessibility of 5S RNA to ribonucleases in Escherichia coli ribosomes

Biochimie, 1971
Summary The accessibility of 5S RNA within 70S ribosomes and 50S subunits to T 1 and pancreatic RNase is studied. It is shown that the ribosomal structure affords a very strong protection to 5S RNA against degradation by ribonucleases. Trypsin digestion can unmask one or several sequences in the 5S RNA which become accessible to pancreatic RNase but

The release of 5S RNA from reticulocyte ribosomes

Biochemical and Biophysical Research Communications, 1970
Abstract Reticulocyte ribosomes were dissociated under various conditions and the release of 5S RNA was assayed. The 5S RNA was released from ribosomes suspended in Tris buffer, pH 9.5, containing EDTA or in Tris buffer, pH 9.5, after dialysis against the same buffer.

Higher order structure of chloroplastic 5S ribosomal RNA from spinach.

Biochemistry, 1988
The secondary and tertiary structure of chloroplastic 5S ribosomal RNA from spinach was investigated by the use of several chemical and enzymatic structure probes.

The nucleotide sequence of ribosomal 5S RNA from sorrel

Biochimie, 1996
The nucleotide sequence of ribosomal 5S RNA from sorrel (Rumex acetosa) was determined. This sequence shows the highest homology to Chenopodiaceae and Cruciferae ribosomal 5S RNA when compared to other dicotyledones' 5S rRNA.

Organization of the 5S ribosomal RNA genes in the genome of tomato

, 1991
The 5S ribosomal RNA (rRNA) genes represent one of the most abundant gene families in eukaryotic genomes and have been a model system for the study of molecular organization and evolution of multigene families in eukaryotes. This paper reports a detailed
