Disease relevance of Haloarcula

  • We searched for ribose zipper tertiary interactions in the crystal structures of the large ribosomal subunit RNAs of Haloarcula marismortui and Deinococcus radiodurans, and the small ribosomal subunit RNA of Thermus thermophilus and identified a total of 97 ribose zippers [1].
 

High impact information on Haloarcula

  • Crystal structures of the Haloarcula marismortui large ribosomal subunit complexed with the 16-membered macrolide antibiotics carbomycin A, spiramycin, and tylosin and a 15-membered macrolide, azithromycin, show that they bind in the polypeptide exit tunnel adjacent to the peptidyl transferase center [2].
  • Protein thermal dynamics was evaluated by neutron scattering for halophilic malate dehydrogenase from Haloarcula marismortui (HmMalDH) and BSA under different solvent conditions [3].
  • Recently, a novel tetrahedral-shaped dodecameric 480-kDa aminopeptidase complex (TET) has been described in Haloarcula marismortui that differs from the known ring- or barrel-shaped self-compartmentalizing proteases [4].
  • We isolated a protein, P45, from the extreme halophilic archaeon Haloarcula marismortui, which displays molecular chaperone activities in vitro [5].
  • The archaeon Haloarcula marismortui has few modifications in the central parts of its 23S ribosomal RNA [6].
 

Biological context of Haloarcula

 

Associations of Haloarcula with chemical compounds

  • Isolated 50 S ribosomal subunits from the halophilic archaebacterium Haloarcula marismortui were treated in situ with the homobifunctional and cleavable crosslinking reagent dithiobis(succinimidyl propionate) (12 A) [9].
  • Malate dehydrogenase from Haloarcula marisomortui (hMDH) is active, soluble and mildly unstable in an unusually wide range of salt conditions and temperatures, making it a particularly interesting model for the study of solvent effects on protein stability [10].
  • The corresponding adenosine residues in the Haloarcula marismortui 50 S ribosomal subunit form a dinucleotide platform, which is quite different from the motif seen in solution [11].
  • Structures of anisomycin, chloramphenicol, sparsomycin, blasticidin S, and virginiamycin M bound to the large ribosomal subunit of Haloarcula marismortui have been determined at 3.0A resolution [12].
  • Purification, characterization, and genetic analysis of Cu-containing dissimilatory nitrite reductase from a denitrifying halophilic archaeon, Haloarcula marismortui [13].
 

Gene context of Haloarcula

  • The gene encoding 37 kDa LRP/p40 has been identified in a variety of species including the sea urchin Urechis caupo, Chlorohydra viridissima, the archaebacterium Haloarcula marismortui, the yeast Saccharomyces cerevisiae as well as in mammals where it is highly conserved [14].
  • The Oligomeric states of Haloarcula marismortui malate dehydrogenase are modulated by solvent components as shown by crystallographic and biochemical studies [15].
  • The C-terminal domain has a protein fold similar to human small nuclear ribonucleoprotein Sm D3 and Haloarcula marismortui ribosomal protein L21E [16].
  • This protein/RNA interface simulates the interaction of L5 with 23S rRNA observed in the Haloarcula marismortui 50S ribosomal subunit [17].
  • Aldolase and glyceraldehyde-3-phosphate dehydrogenase from the extremely halophilic archaebacterium Haloarcula vallismortis are stable only in high concentrations of KCl present within the physiological environment [18].
