  1. ...-reducing hyperthermophilic archaea, belongs to the order Thermococcales in Euryarchaeota along with the closely related genus Pyrococcus . The members of Thermococcus are ubiquitously present in natural high-temperature environments, and are therefore considered to play a major role in the ecology and metabolic activity...
  2. ...challenges. However, the genome reorganization events that drive this process are also the roots of instability for existing operons. We have determined that there exists a statistically significant trend that correlates the proportion of genes encoded in operons in archaea to their phylogenetic lineage. We...
  3. ..._1626, Acel_1628, Acel_1634, Acel_1639, Acel_1643, and Acel_1644) encode proteins that bear highest sequence similarity to proteins from thermophilic bacteria and archaea. With the exception of Acel_1626, homologs of these six proteins do not occur in Frankia . In addition to the three major islands, 21...
  4. ...to result in a (random) loss of one of the two. Thus, once both paths are completed in a cell, one of them, i.e., the DXP path in the lineage leading to eukarya and archaea, or the mevalonate path in bacteria, is discarded. This and later events in the evolution of isoprenoid biosynthesis and lipid side...
  5. ...with decreasing GC content reported in a statistical analysis of the complete s of six thermophilic archaea, two thermophilic bacteria, 17 mesophilic bacteria, and two eukaryotic species ( Kreil and Ouzounis 2001 ). On the other hand, the high frequency of Gly and Arg in C. efficiens concurs with the view...
  6. ...RNA covariance models of the RDP database (Cole et al. 2009). Before defining OTUs, we removed sequences for which the alignment had not been successful (i.e., Infernal bit-score < 0). OTUs were built for both Archaea and Bacteria by hierarchical clustering (complete linkage), at various distances (from 0.2 to 0...
  7. ...duplication is an important mechanistic antecedent to the evolution of new genes and novel biochemical functions. In an attempt to assess the contribution of gene duplication to genome evolution in archaea and bacteria, clusters of related genes that appear to have expanded subsequent to the diversification...
  8. ....T. 1999 . Divergence of the hyperthermophilic archaea Pyrococcus furiosus and P. horikoshii inferred from complete genomic sequences. Genetics 152 : 1299 –1305. ↵ Makino, S. and Suzuki, M. 2001 . Bacterial genomic reorganization upon DNA replication. Science 292 : 803a . ↵ McShan, W.M., Tang, Y...
  9. ...architectures of Halobacterium sp . NRC-1 and H. marismortui suggests a common ancestor for the two organisms and a genome of significantly reduced size in the former. Both of these halophilic archaea use the same strategy of high surface negative charge of folded proteins as means to circumvent the salting...
  10. ...; 5 Genomics Division, Lawrence Berkeley National Laboratory, Berkeley, California 94720, USA Abstract Organisms of the third domain of life, the Archaea, share molecular characteristics both with Bacteria and Eukarya. These organisms attract scientific attention as research models...
