Archaeal family-B DNA polymerases stall replication on encountering the pro-mutagenic bases uracil and hypoxanthine. This publication describes an X-ray crystal structure of Thermococcus gorgonarius polymerase in complex with a DNA containing hypoxanthine in the single-stranded region of the template, two bases ahead of the primer-template junction. Full details of the specific recognition of hypoxanthine are revealed, allowing a comparison with published data that describe uracil binding. The two bases are recognized by the same pocket, in the N-terminal domain, and make very similar protein-DNA interactions. Specificity for hypoxanthine (and uracil) arises from a combination of polymerase-base hydrogen bonds and shape fit between the deaminated bases and the pocket. The structure with hypoxanthine at position 2 explains the stimulation of the polymerase 3-5 proofreading exonuclease, observed with deaminated bases at this location. A beta-hairpin element, involved in partitioning the primer ...

Two halophilic archaea, designated strains WSM-64(T) and WSM-66, were isolated from a sample taken from a borehole in the currently unexploited Barycz mining area belonging to the Wieliczka Salt Mine Company, in Poland. Strains are red pigmented and form non-motile cocci that stain Gram-negative. Strains WSM-64(T) and WSM-66 showed optimum growth at 40 °C, in 20% NaCl and at pH 6.5-7.5. The strains were facultative anaerobes. The major polar lipids of the two strains were phosphatidylglycerol (PG2), phosphatidylglycerol phosphate methyl ester (PGP-Me) and sulfated diglycosyl diether (S-DGD). Menaquinone MK-8 was the major respiratory quinone. The DNA G+C content of strain WSM-64(T) was 61.2 mol% by HPLC method; 61.0 mol% by genome sequencing. Analysis of the almost complete 16S rRNA gene sequence indicated that the strains WSM-64(T) and WSM-66 (99.7% identity) represented a member of the genus Halorhabdus in the family Halobacteriaceae. Both strains formed a distinct cluster and were most ...

A novel halophilic archaeon, strain KeC-11T, was isolated from a seawater aquarium at the Ocean Research Institute, University of Tokyo, Japan. The strain was aerobic, Gram-negative and chemo-organotrophic, growing optimally at 37 °C, at pH 7.0-8.0 and in 2.7 M (16 %) NaCl. The strain required at least 10 mM magnesium ions for growth. Cells of strain KeC-11T were non-motile and generally irregular coccoids or discoids. The DNA G+C content of the isolate was 67.7 mol%. Phylogenetic tree reconstructions indicated that it was distantly related to the other recognized members of the family Halobacteriaceae, with the closest relative being Natronomonas pharaonis GabaraT (91 % sequence similarity). The strain contained C20C20 and C20C25 diether derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, a glycolipid chromatographically identical to the glycosyl-mannosyl-glucosyl diether (TGD-2) and at least one unidentified glycolipid.

Strains C23T and HBSQ001 were isolated from solar salterns and are novel square-shaped, aerobic, extremely halophilic members of the domain Archaea and family Halobacteriaceae. Cells stained Gram-negative and grew optimally in media containing 18 % salts at around neutral pH. Mg2+ is not required. The DNA G+C content of both isolates was 46.9 mol% and DNA-DNA cross-hybridization showed a relatedness of 80 %. Their 16S rRNA gene sequences showed only 2 nucleotide differences (99.9 % identity) and phylogenetic tree reconstructions with other recognized members of the Halobacteriaceae indicated that they formed a distinct clade, with the closest relative being Halogeometricum borinquense PR 3T (91.2 % sequence identity). The major polar glycolipid of both isolates was the sulfated diglycosyl diether lipid S-DGD-1. Electron cryomicrosopy of whole cells revealed similar internal structures, such as gas vesicles and polyhydroxyalkanoate granules, but the cell wall of isolate HBSQ001 displayed a more complex S

Archaea are best known in their capacities as extremophiles, i.e. micro-organisms able to thrive in some of the most drastic environments on Earth. The protein-based surface layer that envelopes many archaeal strains must thus correctly assemble and maintain its structural integrity in the face of the physical challenges associated with, for instance, life in high salinity, at elevated temperatures or in acidic surroundings. Study of archaeal surface-layer (glyco)proteins has thus offered insight into the strategies employed by these proteins to survive direct contact with extreme environments, yet has also served to elucidate other aspects of archaeal protein biosynthesis, including glycosylation, lipid modification and protein export. In this mini-review, recent advances in the study of archaeal surface-layer (glyco)proteins are discussed.

Domain Archaea is currently represented by one phylum (Euryarchaeota) and two superphyla (TACK and DPANN). However, gene surveys indicate the existence of a vast diversity of uncultivated archaea for which metabolic information is lacking. We sequenced DNA from complex sediment- and groundwater-associated microbial communities sampled prior to and during an acetate biostimulation field experiment to investigate the diversity and physiology of uncultivated subsurface archaea. We sampled 15 genomes that improve resolution of a new phylum within the TACK superphylum and 119 DPANN genomes that highlight a major subdivision within the archaeal domain that separates DPANN from TACK/Euryarchaeota lineages. Within the DPANN superphylum, which lacks any isolated representatives, we defined two new phyla using sequences from 100 newly sampled genomes. The first new phylum, for which we propose the name Woesearchaeota, was defined using 54 new sequences. We reconstructed a complete (finished) genome for an ...

So, first a bit of biology. This will make more sense to you if you are not a creationist. Somewhere back in the mists of time -- long before the universe was created 6,000 years ago -- actually somewhere around 2 billion years ago, it seems that 2 (or possibly 3) simple prokaryotic cells entered into an endosymbiotic relationship. We dont know exactly how this happened. Prokaryotic cells dont have a nucleus and are otherwise relatively simple in their internal structure. There are two major kinds, called archaea and bacteria. The most straightforward explanation of the origin of the eukaryotes is that an archaeal cell somehow engulfed a bacterium, but didnt digest it. Instead, the bacterium reproduced and its progeny started living happily within the cytoplasm of the archaea and its descendants. The endosymbiotic bacteria gradually lost most of their DNA -- they didnt need it because their environment was properly managed by the archaeal DNA, which is now our nuclear DNA -- and they settled ...

Thermococcus kodakarensis is a species of thermophilic archaea. The type strain T. kodakarensis KOD1 is one of the best studied members of the genus. T. kodakarensis was isolated from a solfatara near the shore of Kodakara Island, Kagoshima, Japan. The isolate was originally named Pyrococcus kodakarensis KOD1, but reclassified as a species of Thermococcus, based on 16S rRNA sequence. Early research with T. kodakarensis was directed mostly at its thermostable enzymes, but its relative ease of handling and genetic manipulation facilitated by natural competence has made it an attractive system for the study of several biological processes. T. kodakarensis cells are irregular cocci 1-2 μm in diameter, often occurring in pairs, and are highly motile by means of lophotrichous archaella. The cell wall consists of a layer of di-ether and tetra-ether lipids, and an outer glycoprotein coat. T. kodakarensis is an obligate anaerobe, and a heterotroph, growing rapidly on a variety of organic substrates in ...

Cold seeps in the Aleutian deep-sea trench support prolific benthic communities and generate carbonate precipitates which are dependent on carbon dioxide delivered from anaerobic methane oxidation. This process is active in the anaerobic sediments at the sulfate reduction-methane production boundary and is probably performed by archaea working in syntrophic co-operation with sulfate-reducing bacteria. Diagnostic lipid biomarkers of archaeal origin include irregular isoprenoids such as 2,6,11,15-tetramethylhexadecane (crocetane) and 2,6,10,15,19-pentamethylicosane (PMI) as well as the glycerol ether lipid archaeol (2,3-di-O-phytanyl-sn-glycerol). These biomarkers are prominent lipid constituents in the anaerobic sediments as well as in the carbonate precipitates. Carbon isotopic compositions of the biomarkers are strongly depleted in 13C with values of δ13C as low as −130.3‰ PDB. The process of anaerobic methane oxidation is also reflected in the carbon isotope composition of organic matter ...

Thermophilic bacteria and archaea that grow optimally between 50-80°C thrive in deep-sea hydrothermal vent environments. These organisms adapt and evolve unique chemosynthetic mechanisms to flourish in chemically rich vent environments in the complete absence of sunlight. This study examines one such mechanism in which microoganisms utilize Fe(III) oxides to gain energy through the metabolic process of dissimilatory iron reduction. Because the metabolism has not been studied and characterized for thermophilic bacteria and archaea, this thesis investigates the presence of such organisms in hydrothermal fluid samples collected from a diffuse vent site called Marker 113 at Axial Volcano in the northeastern Pacific Ocean. Organisms are isolated and enriched for with Fe(III) to obtain a pure isolate. Iron transformation was determined using ferrozine assays to measure Fe(II) production, and the mechanism utilized was investigated using visualization with scanning electron microscopy and transmission ...

In marine sediments archaea often constitute a considerable part of the microbial community, of which the Deep Sea Archaeal Group (DSAG) is one of the most predominant. Despite their high abundance no members from this archaeal group have so far been characterized and thus their metabolism is unknown. Here we show that the relative abundance of DSAG marker genes can be correlated with geochemical parameters, allowing prediction of both the potential electron donors and acceptors of these organisms. We estimated the abundance of 16S rRNA genes from Archaea, Bacteria, and DSAG in 52 sediment horizons from two cores collected at the slow-spreading Arctic Mid-Ocean Ridge, using qPCR. The results indicate that members of the DSAG make up the entire archaeal population in certain horizons and constitute up to ~50% of the total microbial community. The quantitative data were correlated to 30 different geophysical and geochemical parameters obtained from the same sediment horizons. We observed a significant

Living organisms rely on many different mechanisms to adapt to changes within their environment. Protein phosphorylation and dephosphorylation events are one such way cells can communicate to generate a response to environmental changes. In the Kennelly laboratory we hope to gain insight on phosphorylation events in the domain Archaea through the study of the acidothermophilic organism Sulfolobus solfataricus. Such findings may provide answers into evolutionary relationships and facilitate an understanding of phosphate transfer via proteins in more elaborate systems where pathway disturbances can lead to disease processes. A λ-phage expression library was generated from S. solfataricus genomic DNA. The immobilized expression products were probed with a purified protein kinase, SsoPK4, and radiolabeled ATP to identify potential native substrates. A protein fragment of the ORF sso0563, the catalytic A-type ATPase subunit A (AtpA), was phosphorylated by SsoPK4. Full length and truncated forms of ...

The majority of cells in nature probably exist in a stationary-phase-like state, due to nutrient limitation in most environments. Studies on bacteria and yeast reveal morphological and physiological changes throughout the stationary phase, which lead to an increased ability to survive prolonged nutrient limitation. However, there is little information on archaeal stationary phase responses. We investigated protein- and lipid-level changes in Thermococcus kodakarensis with extended time in the stationary phase. Adaptations to time in stationary phase included increased proportion of membrane lipids with a tetraether backbone, synthesis of proteins that ensure translational fidelity, specific regulation of ABC transporters (upregulation of some, downregulation of others), and upregulation of proteins involved in coenzyme production. Given that the biological mechanism of tetraether synthesis is unknown, we also considered whether any of the protein-level changes in T. kodakarensis might shed light ...

N2 - MTH1203, a β-CASP metallo-β-lactamase family nuclease from the archaeon Methanothermobacter thermautotrophicus, was identified as a putative nuclease that might contribute to RNA processing. The crystal structure of MTH1203 reveals that, in addition to the metallo-β-lactamase nuclease and the β-CASP domains, it contains two contiguous KH domains that are unique to MTH1203 and its orthologs. RNA-binding experiments indicate that MTH1203 preferentially binds U-rich sequences with a dissociation constant in the micromolar range. In vitro nuclease activity assays demonstrated that MTH1203 is a zinc-dependent nuclease. MTH1203 is also shown to be a dimer ...
