• Genes
  • 2009) Diversity of 23S rRNA Genes within Individual Prokaryotic Genomes. (wikipedia.org)
  • They process precursors to ribosomal RNA, small nuclear RNA (snRNA) and small nucleolar RNA (snoRNA) Yeast nucleases with the Class 2 RNase III domain: RNT1 (UniProtKB Q02555) - S. cerevisiae - this RNase III is involved in the transcription and processing of rDNA, the 3' end formation of U2 snRNA via cleavage of the terminal loop, cell wall stress response and degradation, and regulation of morphogenesis checkpoint genes. (wikipedia.org)
  • These are transcribed by RNA polymerase I. 5S occurs in tandem arrays (~200-300 true 5S genes and many dispersed pseudogenes), the largest one on the chromosome 1q41-42. (wikipedia.org)
  • The full-length 23S rRNA genes of Chlamydophila and Chlamydia species are less than 95% identical. (wikipedia.org)
  • binds
  • The amino group of an aminoacyl-tRNA (binds to A site) attacks the carbon of a carbonyl group of a peptidyl-tRNA (binds to P site) and finally yields a peptide extended by one amino acid esterified to the A site tRNA bound to the ribosomal A site and a deacylated tRNA in the P site. (wikipedia.org)
  • nucleotides
  • Dicer enzymes process dsRNA subtrates into small RNA fragments of individual size ranging from 21-27 nucleotides in length. (wikipedia.org)
  • structures
  • The impressive increase of novel RNA structures, during the past few years, demands automated methods for structure comparison. (pubmedcentralcanada.ca)
  • The FRASS web-server represents a RNA chain with its Gauss integrals and allows one to compare structures of RNA chains and to find similar entries in a database derived from the Protein Data Bank. (pubmedcentralcanada.ca)
  • Moreover, the-web server can also reproduce satisfactorily the DARTS classification of RNA 3D structures and the classification of the SCOR functions that was obtained by the SARA method. (pubmedcentralcanada.ca)
  • The FR3D [ 9 ] method was also developed for finding local motifs in RNA structures. (pubmedcentralcanada.ca)
  • It was later extended, by the RNA Ontology Consortium, into the "consensus modular string nomenclature" for RNA structures, which includes 46 discrete conformers represented by two characters [ 11 ]. (pubmedcentralcanada.ca)
  • Processes of ribosomal RNA (rRNA) expansion can be "observed" by comparing 3D rRNA structures of bacteria (small), yeast (medium), and metazoans (large). (pnas.org)
  • Some of the most common motifs for RNA and DNA tertiary structure are described below, but this information is based on a limited number of solved structures. (wikipedia.org)
  • Quadruplexes Although the major groove of standard A-form RNA is fairly narrow and therefore less available for triplex interaction than the minor groove, major groove triplex interactions can be observed in several RNA structures. (wikipedia.org)
  • There are diverse structures of RNA base quadruplexes. (wikipedia.org)
  • A1067
  • 23S rRNA (adenosine1067-2'-O)-methyltransferase (EC 2.1.1.230, 23S rRNA A1067 2'-methyltransferase, thiostrepton-resistance methylase, nosiheptide-resistance methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (adenosine1067-2'-O)-methyltransferase. (wikipedia.org)
  • enzyme
  • The cell uses as a template for repair the 23S allele that yielded the responsible I-CreI enzyme, thus replicating the I-CreI-containing intron. (wikipedia.org)
  • This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + adenosine1067 in 23S rRNA ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + 2'-O-methyladenosine1067 in 23S rRNA The methylase that is responsible for autoimmunity in the thiostrepton producer Streptomyces azureus. (wikipedia.org)
  • 23S rRNA (uridine2552-2'-O)-methyltransferase (EC 2.1.1.166, Um(2552) 23S ribosomal RNA methyltransferase, heat shock protein RrmJ, RrmJ, FTSJ, Um2552 methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (uridine2552-2'-O-)-methyltransferase. (wikipedia.org)
  • This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + uridine2552 in 23S rRNA ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + 2'-O-methyluridine2552 in 23S rRNA The enzyme catalyses the 2'-O-methylation of the universally conserved U2552 in the A loop of 23S rRNA.

  • Mechanism
  • They are ubiquitous compounds in the cell and play a major role in pathways such as RNA precursor synthesis, RNA Silencing, and the pnp autoregulatory mechanism. (wikipedia.org)
  • residues
  • Covalent crosslinking of tRNAval1 to 16S RNA at the ribosomal P site: identification of the crosslinked residues. (springer.com)
  • Four consecutive guanine residues can form a quadruplex in RNA by Hoogsteen hydrogen bonds to form a "Hoogsteen ring" (See Figure). (wikipedia.org)
  • amino acid
  • RNA editing results in an alternative amino acid being translated. (wikipedia.org)
  • An open reading frame coding for a 163-amino acid protein was found in this 23S intron, suggesting that a protein might facilitate the homing behavior of the mobile intron. (wikipedia.org)
