5 S rRNA: structure and interactions.
5 S rRNA is an integral component of the large ribosomal subunit in all known organisms. Despite many years of intensive study, the function of 5 S rRNA in the ribosome remains unknown. Advances in the analysis of ribosome structure that have revealed the crystal structures of large ribosomal subunits and of the complete ribosome from various organisms put the results of studies on 5 S rRNA in ...
متن کاملThe use of chemical nucleases to analyze RNA-protein interactions. The TFIIIA-5 S rRNA complex.
The complex of Xenopus transcription factor IIIA (TFIIIA) with 5 S rRNA was analyzed in nuclease protection experiments using hydroxyl radical. The protection pattern reveals that TFIIIA interacts with a substantial amount of the RNA molecule, with close association between the factor and the arm of the RNA composed of helix IV-loop E-helix V. Additional sites of protection punctuate the other ...
متن کاملMapping ribosomal protein S20-16 S rRNA interactions by mutagenesis.
Specific ribonucleotides within the 5' domain of Escherichia coli 16 S rRNA were altered by deletion and/or substitution by site-directed mutagenesis of cloned DNA to assess the importance of these particular residues in defining the binding site for ribosomal protein S20. Gel filtration and sucrose gradient centrifugation were employed to measure the binding of ribosomal protein S20 to synthet...

متن کاملSecondary structure of 5 S ribosomal RNA.
A secondary structure model for 16S ribosomal RNA which is based on available chemical, enzymatic, and comparative sequence data shows good agreement between constraints dictated by the model and a wide variety of experimental observations. The four major structural domains created by the base-pairing scheme correspond closely to RNA fragments isolated after nuclease digestion in the presence o...
