  • Ribosomal
  • Regulated by the binding and hydrolysis of guanosine triphosphates, the RNA-bound SRP54 protein transiently associates not only with the hydrophobic signal sequence as it emerges from the ribosomal exit tunnel, but also interacts with the membrane-associated SRP receptor (FtsY). (hindawi.com)
  • genome
  • Polypeptides which are homologous to the eukaryal SRP9/14 and SRP68/72 heterodimers have not been found in the archaea genome sequences giving rise to an archaea SRP which is dominated by RNA [ 3 , 4 ]. (hindawi.com)
  • We describe here the identification of novel RNA viral genome segments from high-temperature acidic hot springs in Yellowstone National Park in the United States. (asm.org)

  • showed evidence that CRISPR repeat regions from the genome of Archaeoglobus fulgidus were transcribed into long RNA molecules that were subsequently processed into unit-length small RNAs, plus some longer forms of 2, 3, or more spacer-repeat units. (wikipedia.org)
  • The human genome in particular is known to contain a large amount of SRP RNA related sequence, including Alu repeats. (genecards.org)
  • Sulfolobus
  • The reversible thermal unfolding of the archaeal histone-like protein Ssh10b from the extremophile Sulfolobus shibatae was studied using differential scanning calorimetry and circular dichroism spectroscopy. (ox.ac.uk)

  • STRUCTURES
  • Whereas ordered tree matching based on seeded nodes has applications in pattern matching of RNA structures, unordered tree matching based on seeded nodes has applications in co-speciation and phylogeny reconciliation. (springer.com)
  • double-stranded
  • RNAP locally opens the double-stranded DNA (usually about four turns of the double helix) so that one strand of the exposed nucleotides can be used as a template for the synthesis of RNA , a process called transcription . (wikipedia.org)
  • fulgidus
  • Identification of 86 candidates for small non-messenger RNAs from the archaeon Archaeoglobus fulgidus," Proceedings of the National Academy of Sciences of the United States of America , vol. 99, no. 11, pp. 7536-7541, 2002. (hindawi.com)
  • pseudogenes
  • Many sequences below the threshold for this family are clearly closely related, but are most likely to be SRP RNA derived pseudogenes. (genecards.org)
  • genomes
  • A viral metagenomics approach was taken to assemble segments of these RNA virus genomes from viral populations isolated directly from hot spring samples. (asm.org)
  • viruses
  • Fewer than 50 archaeal viruses have been discovered, compared to more than 5,500 viruses known to infect hosts from the other two domains of life ( 2 ). (asm.org)
  • One factor limiting the discovery of archaeal viruses has been the reliance on culture-dependent approaches for virus isolation. (asm.org)
  • RNA polymerase is essential to life, and is found in all living organisms and many viruses. (wikipedia.org)
  • sequences
  • Analysis of archaeal amoA sequences obtained from the fungiid coral, Fungia granulosa, divided into three clades, all related to archaeal sequences previously obtained from the marine environment. (edu.au)
