Crenarchaeota
A kingdom in the domain ARCHAEA comprised of thermoacidophilic, sulfur-dependent organisms. The two orders are SULFOLOBALES and THERMOPROTEALES.
Archaea
One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.
Korarchaeota
A kingdom in the domain ARCHAEA, comprising thermophilic organisms from terrestrial hot springs that are among the most primitive of all life forms. They have undergone comparatively little evolutionary change since the last common ancestor of all extant life.
Quercetin
Euryarchaeota
A phylum of ARCHAEA comprising at least seven classes: Methanobacteria, Methanococci, Halobacteria (extreme halophiles), Archaeoglobi (sulfate-reducing species), Methanopyri, and the thermophiles: Thermoplasmata, and Thermococci.
Archaeoglobus fulgidus
A species of extremely thermophilic, sulfur-reducing archaea. It grows at a maximum temperature of 95 degrees C. in marine or deep-sea geothermal areas.
Archaeoglobus
A genus of extremely thermophilic, sulfate-reducing archaea, in the family Archaeoglobaceae.
Chemoautotrophic Growth
Growth of organisms using AUTOTROPHIC PROCESSES for obtaining nutrients and chemotrophic processes for obtaining a primary energy supply. Chemotrophic processes are involved in deriving a primary energy supply from exogenous chemical sources. Chemotrophic autotrophs (chemoautotrophs) generally use inorganic chemicals as energy sources and as such are called chemolithoautotrophs. Most chemoautotrophs live in hostile environments, such as deep sea vents. They are mostly BACTERIA and ARCHAEA, and are the primary producers for those ecosystems.

Martinique
An island in the Lesser Antilles, one of the Windward Islands. Its capital is Fort-de-France. It was discovered by Columbus in 1502 and from its settlement in 1635 by the French it passed into and out of Dutch and British hands. It was made a French overseas department in 1946. One account of the name tells of native women on the shore calling "Madinina" as Columbus approached the island. The meaning was never discovered but was entered on early charts as Martinique, influenced by the name of St. Martin. (From Webster's New Geographical Dictionary, 1988, p734 & Room, Brewer's Dictionary of Names, 1992, p339)
Atlantic Islands
Widely scattered islands in the Atlantic Ocean as far north as the AZORES and as far south as the South Sandwich Islands, with the greatest concentration found in the CARIBBEAN REGION. They include Annobon Island, Ascension, Canary Islands, Falkland Islands, Fernando Po (also called Isla de Bioko and Bioko), Gough Island, Madeira, Sao Tome and Principe, Saint Helena, and Tristan da Cunha.
Shared Paranoid Disorder
Factor V
Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.
Prothrombin
A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.
Ameloblasts
Cylindrical epithelial cells in the innermost layer of the ENAMEL ORGAN. Their functions include contribution to the development of the dentinoenamel junction by the deposition of a layer of the matrix, thus producing the foundation for the prisms (the structural units of the DENTAL ENAMEL), and production of the matrix for the enamel prisms and interprismatic substance. (From Jablonski's Dictionary of Dentistry, 1992)
Bacterial origin for the isoprenoid biosynthesis enzyme HMG-CoA reductase of the archaeal orders Thermoplasmatales and Archaeoglobales. (1/9)
The enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase or HMGR) fulfills an essential role in archaea, as it is required for the synthesis of isoprenoid ethers, the main component of archaeal cell membranes. There are two clearly homologous but structurally different classes of the enzyme, one found mainly in eukaryotes and archaea (class 1), and the other found in bacteria (class 2). This feature facilitated the identification of several cases of interdomain lateral gene transfer (LGT), in particular, the bacterial origin for the HMGR gene from the archaeon Archaeoglobus fulgidus. In order to investigate if this LGT event was recent and limited in its scope or had a broad and long-term impact on the recipient and its related lineages, the HMGR gene was amplified and sequenced from a variety of archaea. The survey covered close relatives of A. fulgidus, the only archaeon known prior to this study to possess a bacterial-like HMGR; representatives of each main euryarchaeal group were also inspected. All culturable members of the archaeal group Archaeoglobales were found to display an HMGR very similar to the enzyme of the bacterium Pseudomonas mevalonii. Surprisingly, two species of the genus Thermoplasma also harbor an HMGR of bacterial origin highly similar to the enzymes found in the Archaeoglobales. Phylogenetic analyses of the HMGR gene and comparisons to reference phylogenies from other genes confirm a common bacterial origin for the HMGRs of Thermoplasmatales and Archaeoglobales. The most likely explanation of these results includes an initial bacteria-to-archaea transfer, followed by a another event between archaea. Their presence in two divergent archaeal lineages suggests an important adaptive role for these laterally transferred genes. (+info)Characterisation of Archaeglobus fulgidus AlkA hypoxanthine DNA glycosylase activity. (2/9)
The AlkA protein from the archaebacterium Archaeglobus fulgidus was characterised with respect to release of hypoxanthine from DNA. The hypoxanthine glycosylase activity had optimal activity at 60 degrees C at pH 5.0. The enzyme released hypoxanthine from substrates with a preference for dI:dG >> dI:dT > dI:dC > dI:dA. The presence of a mismatch on either side of the dIMP in the substrate reduced excision efficiency of the hypoxanthine residue at neutral pH, while a mismatch on both sides of the dIMP resulted in total loss of excision. Release of hypoxanthine from DNA required a minimum of two bases on the 5' side and four bases on the 3' side of the dIMP residue. (+info)Structural and thermodynamic evidence for a stabilizing role of Nop5p in S-adenosyl-L-methionine binding to fibrillarin. (3/9)
In Archaea, fibrillarin and Nop5p form the core complex of box C/D small ribonucleoprotein particles, which are responsible for site-specific 2'-hydroxyl methylation of ribosomal and transfer RNAs. Fibrillarin has a conserved methyltransferase fold and employs S-adenosyl-l-methionine (AdoMet) as the cofactor in methyl transfer reactions. Comparison between recently determined crystal structures of free fibrillarin and fibrillarin-Nop5p-AdoMet tertiary complex revealed large conformational differences at the cofactor-binding site in fibrillarin. To identify the structural elements responsible for these large conformational differences, we refined a crystal structure of Archaeoglobus fulgidus fibrillarin-Nop5p binary complex at 3.5 A. This structure exhibited a pre-formed backbone geometry at the cofactor binding site similar to that when the cofactor is bound, suggesting that binding of Nop5p alone to fibrillarin is sufficient to stabilize the AdoMet-binding pocket. Calorimetry studies of cofactor binding to fibrillarin alone and to fibrillarin-Nop5p binary complex provided further support for this role of Nop5p. Mutagenesis and thermodynamic data showed that a cation-pi bridge formed between Tyr-89 of fibrillarin and Arg-169 of Nop5p, although dispensable for in vitro methylation activity, could partially account for the enhanced binding of cofactor to fibrillarin by Nop5p. Finally, assessment of cofactor-binding thermodynamics and catalytic activities of enzyme mutants identified three additional fibrillarin residues (Thr-70, Glu-88, and Asp-133) to be important for cofactor binding and for catalysis. (+info)Heat shock response of Archaeoglobus fulgidus. (4/9)
The heat shock response of the hyperthermophilic archaeon Archaeoglobus fulgidus strain VC-16 was studied using whole-genome microarrays. On the basis of the resulting expression profiles, approximately 350 of the 2,410 open reading frames (ORFs) (ca. 14%) exhibited increased or decreased transcript abundance. These span a range of cell functions, including energy production, amino acid metabolism, and signal transduction, where the majority are uncharacterized. One ORF called AF1298 was identified that contains a putative helix-turn-helix DNA binding motif. The gene product, HSR1, was expressed and purified from Escherichia coli and was used to characterize specific DNA recognition regions upstream of two A. fulgidus genes, AF1298 and AF1971. The results indicate that AF1298 is autoregulated and is part of an operon with two downstream genes that encode a small heat shock protein, Hsp20, and cdc48, an AAA+ ATPase. The DNase I footprints using HSR1 suggest the presence of a cis-binding motif upstream of AF1298 consisting of CTAAC-N5-GTTAG. Since AF1298 is negatively regulated in response to heat shock and encodes a protein only distantly related to the N-terminal DNA binding domain of Phr of Pyrococcus furiosus, these results suggest that HSR1 and Phr may belong to an evolutionarily diverse protein family involved in heat shock regulation in hyperthermophilic and mesophilic Archaea organisms.

Sulfolobales
Exposure of Sulfolobus solfataricus to the DNA damaging agents UV-irradiation, bleomycin or mitomycin C induces cellular aggregation.[2] Other physical stressors, such as pH or temperature shift, do not induce aggregation, suggesting that induction of aggregation is caused specifically by DNA damage. Ajon et al.[3] showed that UV-induced cellular aggregation mediates chromosomal marker exchange with high frequency. Recombination rates exceeded those of uninduced cultures by up to three orders of magnitude. Frols et al.[2][4] and Ajon et al.[3] hypothesized that the UV-inducible DNA transfer process and subsequent homologous recombinational repair represents an important mechanism to maintain chromosome integrity. This response may be a primitive form of sexual interaction, similar to the more well-studied bacterial transformation that is also associated with DNA transfer between cells leading to homologous recombinational repair of DNA damage.[5] In another related species, Sulfolobus ...

Arkea ada di berbagai habitat, dan sebagai bagian utama dari ekosistem global,[14] dapat berkontribusi hingga 20% dari biomassa bumi.[155] Arkea yang pertama ditemukan adalah ekstremofili.[108] Memang, beberapa arkea bertahan pada suhu tinggi, sering di atas 100 °C (212 °F), seperti yang ditemukan di geyser, perokok hitam, dan sumur minyak. Habitat umum lainnya termasuk habitat yang sangat dingin dan air yang sangat asin, asam, atau alkali. Namun, arkea mencakup mesofil yang tumbuh dalam kondisi ringan, di tanah rawa, air limbah, samudra, saluran usus hewan, dan tanah.[14]. Arkea ekstremofil adalah anggota empat kelompok fisiologis utama. Kelompok-kelompok itu adalah halofili, termofili, alkalifili, dan asidofili.[156] Kelompok-kelompok ini tidak komprehensif atau filum-spesifik, mereka juga tidak saling eksklusif, karena beberapa archaea termasuk dalam beberapa kelompok. Meskipun demikian, mereka adalah titik awal yang berguna untuk klasifikasi.. Halofili, termasuk genus Halobacterium, hidup ...

Este grupo comprende as ordes Thermoproteales, Sulfolobales, Desulfurococcales e Caldisphaerales (pero propuxéronse cambios), e inclúe as especies coas temperaturas de crecemento máis altas de calquera organismo coñecido. O crecemento óptimo realízase entre 75 e 105 °C, e a temperatura máxima de crecemento para Pyrolobus chega a 113 °C. A maioría destas especies non poden crecer por debaixo de 70 °C, aínda que poden sobrevivir por períodos longos a baixas temperaturas. Algunhas especies son acidófilas cun pH óptimo entre 1,5 e 4 e morren a pH 7, e outras son neutrófilas ou lixeiramente acidófilas, crecendo optimamente a un pH de 5,5-7,5. Encóntranse en hábitats volcánicos tales como mananciais quentes continentais e en fontes hidrotermais do fondo oceánico, a pouca ou moita profundidade.

Archaea exist in a broad range of habitats, and as a major part of global ecosystems,[14] may represent about 20% of microbial cells in the oceans.[159] The first-discovered archaeans were extremophiles.[112] Indeed, some archaea survive high temperatures, often above 100 °C (212 °F), as found in geysers, black smokers, and oil wells. Other common habitats include very cold habitats and highly saline, acidic, or alkaline water. However, archaea include mesophiles that grow in mild conditions, in swamps and marshland, sewage, the oceans, the intestinal tract of animals, and soils.[14]. Extremophile archaea are members of four main physiological groups. These are the halophiles, thermophiles, alkaliphiles, and acidophiles.[160] These groups are not comprehensive or phylum-specific, nor are they mutually exclusive, since some archaea belong to several groups. Nonetheless, they are a useful starting point for classification.. Halophiles, including the genus Halobacterium, live in extremely saline ...

- Ferroglobus placidus belongs to the order Archaeoglobales within the archaeal phylum Euryarchaeota . (standardsingenomics.org)
Archaea5
- This section lists the genera of Archaea within the Order Archaeoglobales. (wikipedia.org)
- As arqueas ( Archaea , do grego ἀρχαῖα 'os antigos') son un grupo de microorganismos unicelulares de morfoloxía procariótica (sen núcleo nin, en xeral, orgánulos membranosos internos), que forman un dos tres grandes dominios dos seres vivos, e que son diferentes das bacterias . (wikipedia.org)
- As Archaea divídense en cinco filos recoñecidos, pero pénsase que poden haber máis. (wikipedia.org)
- These formate or lactate consuming sulfate reducers were dominated by Archaeoglobales (7% in situ) and unidentified Archaea. (springer.com)
- Archaea in the high salinity surface sediments were dominated by the orders Archaeoglobales and Thermococcales , transitioning to Thermoproteales and Desulfurococcales ( Staphylothermus sp . (darkenergybiosphere.org)
Halobacteriales1
- It was likely lost in the Halobacteriales, Thermoplasmatales and Archaeoglobales. (hindawi.com)
Thermococcales1
- Typically, if a microbe can survive somewhere, it will, so the absence of hyperthermophiles like Thermococcales , Methanococcales , and Archaeoglobales seemed like one of the surprisingly few examples of organisms not filling the maximal extent of their niche space. (discovermagazine.com)
Stetter1
- Archaeoglobales Huber and Stetter 2002, ord. (bacterio.net)
Genus1
- Based on detailed analysis of its 16S rDNA sequence, G+C content, distinguishing physiological features and metabolism, strain 234T is proposed to represent a novel genus within the Archaeoglobales. (umass.edu)
