5S Ribosomal RNA Database
Ribosomal 5S RNA (5S rRNA) is an integral component of the large ribosomal subunit in all known organisms with the exception only of mitochondrial ribosomes of fungi and animals. It is thought to enhance protein synthesis by stabilization of a ribosome structure. This paper presents the updated database of 5S rRNA and their genes (5S rDNA). Its short characteristics are presented in the Introdu...
متن کاملElectron microscopic study of crystals of the Xenopus laevis transcription factor IIIA-5S ribosomal RNA complex.
A novel method has been developed to grow crystals of the Xenopus laevis transcription factor IIIA-5S RNA complex directly on grids for examination by electron microscopy. Microcrystals were examined in negative stain and in thin sections to reveal a hexagonal lattice with unit-cell dimensions a = b = 87.1 +/- 4.4 A and c = 143.8 +/- 12.7 A. Optical diffraction patterns from micrographs were ob...
متن کامل5S ribosomal RNA database Y2K
This paper presents the updated version (Y2K) of the database of ribosomal 5S ribonucleic acids (5S rRNA) and their genes (5S rDNA), http://rose.man/poznan.pl/5SData/index.html. This edition of the database contains 1985primary structures of 5S rRNA and 5S rDNA. They include 60 archaebacterial, 470 eubacterial, 63 plastid, nine mitochondrial and 1383 eukaryotic sequences. The nucleotide sequenc...
متن کاملPurification of human transcription factor IIIC and its binding to the gene for ribosomal 5S RNA.
Transcription factor hTFIIIC was purified from cytoplasmic extracts of HeLa cells using four different chromatographic steps. This procedure yields a protein fraction which actively supports transcription in reconstitution assays and contains five major polypeptide chains with a molecular mass ranging from 25 to 250 kDa as estimated by SDS-PAGE and silver staining. In this fraction a polypeptid...
متن کاملIsolation of rat liver 5S RNA genes.
A method for the isolation of structural genes, whose transcripts do not contain terminal poly(A) sequences, is presented. Poly(A) tails of predicted length were synthesized at the 3'-OH ends of RNA molecules employing Escherichia coli ATP : RNA adenyltransferase (EC 2.7.7.19). The gene isolation was performed in two steps: (a) enrichment of DNA fragments carrying the genes of interest, (b) sub...
