  1. Analysis of synonymous codon usage in Aeropyrum pernix K1 and other Crenarchaeota microorganisms.
    Peng Jiang, Xiao Sun, and Zuhong Lu

    J Genet Genomics 34(3):275-84 (2007) PMID 17498625

    In this study, a comparative analysis of the codon usage bias was performed in Aeropyrum pernix K1 and two other phylogenetically related Crenarchaeota microorganisms (i.e., Pyrobaculum aerophilum str. IM2 and Sulfolobus acidocaldarius DSM 639). The results indicated that the synonymous codon usage...
  2. Diversity of Archaea in marine sediments from Skan Bay, Alaska, including cultivated methanogens, and description of Methanogenium boonei sp...
    Melissa M MM Kendall, George D GD Wardlaw, ... David L DL Valentine

    Appl Environ Microbiol 73(2):407-14 (2007) PMID 17122405 PMCID 1796967

    We employed a multidisciplinary approach that combined culture-dependent and -independent analyses with geochemical measurements in the sediments of Skan Bay, Alaska (53 degrees N, 167 degrees W), to investigate methanogenesis there. Cultivation-independent analyses of the archaeal community reveale...
  3. Clusters of orthologous genes for 41 archaeal genomes and implications for evolutionary genomics of archaea
    Kira S Makarova, Alexander V Sorokin, ... Eugene V Koonin

    Biol Direct 2(1):33 (2007) PMID 18042280

  4. Novel soil lineages of Archaea are present in semi-arid soils of eastern Australia.
    David J DJ Midgley, Jennifer A JA Saleeba, ... Peter A PA McGee

    Can J Microbiol 53(1):129-38 (2007) PMID 17496958

    The diversity of Archaea was studied in vertisolic and loam soils of a semi-arid region in Australia. Sampling was undertaken at an agricultural site, two grassland environments, and a brigalow (Acacia harpophylla) woodland. Archaeal community structure was profiled using amplified ribosomal DNA res...
  5. Metagenomic studies reveal the critical and wide-ranging ecological importance of uncultivated Archaea: the role of ammonia oxidizers.
    Ricardo R Cavicchioli, Matthew Z MZ Demaere, and Torsten T Thomas

    Bioessays 29(1):11-4 (2007) PMID 17187352

    Microbial genome sequencing has entered a new phase, where DNA sequence information is gathered from entire microbial communities (metagenomics or environmental genomics) rather than from individual microorganisms. By providing access to the genetic material of vast numbers of organisms, most of whi...
  6. Orthologs of the small RPB8 subunit of the eukaryotic RNA polymerases are conserved in hyperthermophilic Crenarchaeota and "Korarchaeota".
    Eugene V EV Koonin, Kira S KS Makarova, and James G JG Elkins

    Biol Direct (2007) PMID 18081935 PMCID 2234397

    We report that orthologs of RPB8 are encoded in all sequenced genomes of hyperthermophilic Crenarchaeota and a recently sequenced "korarchaeal" genome, but not in Euryarchaeota or the mesophilic crenarchaeon Cenarchaeum symbiosum. These findings suggest that all 12 core subunits of eukaryotic RNAPs...

  7. CC1, a novel crenarchaeal DNA binding protein.
    Xiao X Luo, Uli U Schwarz-Linek, ... Malcolm F MF White

    J Bacteriol 189(2):403-9 (2007) PMID 17085561 PMCID 1797387

    We performed a biochemical screen for novel nucleic acid binding proteins present in cell extracts of T. tenax. An assay for proteins capable of binding to a single-stranded DNA oligonucleotide resulted in identification of three proteins. The first protein, Alba, has been shown previously to bind s...

  9. Phylogenetic diversity of planktonic archaea in the estuarine region of East China Sea
    Yonghui Zeng, Heyang Li, and Nianzhi Jiao

    Microbiol Res 162(1):11 (2007) PMID 16914298

    I (MGI) and Marine Group II (MGII) which are affiliated with the phyla Crenarchaeota and Euryarchaeota, respectively. MGI clones dominate both libraries with 20 MGI sequences obtained. The majority of sequences are closely related to uncultured marine archaea except for two sequences of which the ne...
  10. Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis.
    Beile B Gao and Radhey S RS Gupta

    BMC Genomics (2007) PMID 17394648 PMCID 1852104

    We have carried out comprehensive analyses on each open reading frame (ORFs) in the genomes of 11 archaea (3 Crenarchaeota--Aeropyrum pernix, Pyrobaculum aerophilum and Sulfolobus acidocaldarius; 8 Euryarchaeota--Pyrococcus abyssi, Methanococcus maripaludis, Methanopyrus kandleri, Methanococcoides b...
