Nucleotide sequences of accessible regions of 23S RNA in 50S ribosomal subunits

Biochemistry, 1978
Nucleotide sequences around kethoxal-reactive guanine residues of 23S RNA in 50S ribosomal subunits have been determined. By use of the diagonal paper electrophoresis method )Noller, H.F. (1974), Biochemistry 13, 4694-4703), 41 ribonuclease T1 oligonucleotides, originating from about 25 sites, were identified and sequenced.

Thiostrepton resistance mutations in the gene for 23S ribosomal RNA of Halobacteria

Biochimie, 1987
Mutants of Halobacterium (H.) halobium and H. cutirubrum were isolated which are resistant to the 70S ribosome inhibitor thiostrepton. Using primer extension analysis, resistance was shown to correlate with base changes at position 1159, which corresponds to position 1067 of the E. coli 23S rRNA.

Sequence Analysis of Specific Areas of the 16S and 23S Ribosomal RNAs

Nature, 1968
These ribosomal RNAs seem to be largely homogeneous, at least with respect to the methylated sequences. Methylation is very specific and occurs at a small number of loci.

Atypical Structure of the 23S Ribosomal RNA Molecule in Certain Oral Bacteria

Journal of Dental Research, 1991
Ribosomal RNA (rRNA) isolated from Wolinella recta and seven related bacteria was examined by agarose gel electrophoresis. The 23S rRNA molecule could not be detected in W. recta, Wolinella curva, Bacteroides gracilis, or Bacteroides ureolyticus. In place of the 23S molecule, there were three smaller molecules of approximately 1700, 650, and 600 bases

[74] Photoaffinity labeling of 23 S RNA in ribosomes

1977
Publisher Summary Photoaffinity labeling—a well known technique for studying active sites in enzymes—has attracted considerable attention as a tool to ascertain structure-function relationships in more complex biological structures, such as ribosomal binding sites or membrane receptor sites.

Recognition of nucleotide G745 in 23 S ribosomal RNA by the RrmA methyltransferase

Journal of Molecular Biology, 2001
Methylation of the N1 position of nucleotide G745 in hairpin 35 of Escherichia coli 23 S ribosomal RNA (rRNA) is mediated by the methyltransferase enzyme RrmA. Lack of G745 methylation results in reduced rates of protein synthesis and growth. Addition of recombinant plasmid-encoded rrmA to an rrmA-deficient strain remedies these defects.

The relationship between precursor and mature forms of the 23 S ribosomal RNA

Journal of Molecular Evolution, 1973
Oligonucleotide fingerprinting shows the precursor form of the 23S ribosomal RNA fromBacillus megaterium to be larger than its mature counterpart, by some 8 percent, or approximately 250 nucleotides. It can further be shown that the 23SrRNA precursor doesnot contain the 5SrRNA sequence, as had been previously suggested.

Mutations at position A960 of E. coli 23 S ribosomal RNA influence the structure of 5 S ribosomal RNA and the peptidyltransferase region of 23 S ribosomal RNA.

Journal of molecular biology, 2000
The proximity of loop D of 5 S rRNA to two regions of 23 S rRNA, domain II involved in translocation and domain V involved in peptide bond formation, is known from previous cross-linking experiments. Here, we have used site-directed mutagenesis and chemical probing to further define these contacts and possible sites of communication between 5 S and 23 ...
