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.

Cloning, expression, and characterization of the first archaeal ATP-dependent glucokinase from aerobic hyperthermophilic archaeon Aeropyrum pernix. (1/73)

The gene encoding the ATP-dependent glucokinase of hyperthermophilic archaeon Aeropyrum pernix was identified, cloned, and functionally expressed in Escherichia coli. The deduced amino acid sequence showed 40% identity to that of the putative glucokinase from hyperthermophilic archaeon Pyrobacurum aerophilum. The purified recombinant enzyme was a monomer with a molecular mass of 35 kDa. The enzyme retained its full activity on heating at 70 degrees C for 10 min and retained 65% of the activity after 10-min incubation at 100 degrees C. The enzyme exclusively catalyzed the phosphorylation of D-glucose using ATP as a phosphoryl donor. ITP was accepted in addition to ATP. The rate dependence with both glucose and ATP followed Michaelis-Menten kinetics, with apparent K(m) values of 0.054 and 0.50 mM, respectively. The enzyme activity required divalent cations; Mg(2+), which was most effective, could partially be replaced by Mn(2+) or Ca(2+). Phylogenetic analysis revealed that the glucokinase from A. pernix does not belong to the clusters of enzymes found in bacteria and eukarya. This is the first description of the characteristics of an ATP-dependent glucokinase from an archaeon.  (+info)

Comparison of sequence masking algorithms and the detection of biased protein sequence regions. (2/73)

MOTIVATION: Separation of protein sequence regions according to their local information complexity and subsequent masking of low complexity regions has greatly enhanced the reliability of function prediction by sequence similarity. Comparisons with alternative methods that focus on compositional sequence bias rather than information complexity measures have shown that removal of compositional bias yields at least as sensitive and much more specific results. Besides the application of sequence masking algorithms to sequence similarity searches, the study of the masked regions themselves is of great interest. Traditionally, however, these have been neglected despite evidence of their functional relevance. RESULTS: Here we demonstrate that compositional bias seems to be a more effective measure for the detection of biologically meaningful signals. Typical results on proteins are compared to results for sequences that have been randomized in various ways, conserving composition and local correlations for individual proteins or the entire set. It is remarkable that low-complexity regions have the same form of distribution in proteins as in randomized sequences, and that the signal from randomized sequences with conserved local correlations and amino acid composition almost matches the signal from proteins. This is not the case for sequence bias, which hence seems to be a genuinely biological phenomenon in contrast to patches of low complexity.  (+info)

Bifunctional phosphoglucose/phosphomannose isomerases from the Archaea Aeropyrum pernix and Thermoplasma acidophilum constitute a novel enzyme family within the phosphoglucose isomerase superfamily. (3/73)

The hyperthermophilic crenarchaeon Aeropyrum pernix contains phosphoglucose isomerase (PGI) activity. However, obvious homologs with significant identity to known PGIs could not be identified in the sequenced genome of this organism. The PGI activity from A. pernix was purified and characterized. Kinetic analysis revealed that, unlike all known PGIs, the enzyme catalyzed reversible isomerization not only of glucose 6-phosphate but also of epimeric mannose 6-phosphate at similar catalytic efficiency, thus defining the protein as bifunctional phosphoglucose/phosphomannose isomerase (PGI/PMI). The gene pgi/pmi encoding PGI/PMI (open reading frame APE0768) was identified by matrix-assisted laser desorption ionization time-of-flight analyses; the gene was overexpressed in Escherichia coli as functional PGI/PMI. Putative PGI/PMI homologs were identified in several (hyper)thermophilic archaea and two bacteria. The homolog from Thermoplasma acidophilum (Ta1419) was overexpressed in E. coli, and the recombinant enzyme was characterized as bifunctional PGI/PMI. PGI/PMIs showed low sequence identity to the PGI superfamily and formed a distinct phylogenetic cluster. However, secondary structure predictions and the presence of several conserved amino acids potentially involved in catalysis indicate some structural and functional similarity to the PGI superfamily. Thus, we propose that bifunctional PGI/PMI constitutes a novel protein family within the PGI superfamily.  (+info)

Aeropyrum camini sp. nov., a strictly aerobic, hyperthermophilic archaeon from a deep-sea hydrothermal vent chimney. (4/73)

A novel hyperthermophilic archaeon, designated strain SY1(T), was isolated from a deep-sea hydrothermal vent chimney sample collected from the Suiyo Seamount in the Izu-Bonin Arc, Japan, at a depth of 1385 m. The cells were irregular cocci (1.2 to 2.1 micro m in diameter), occurring singly or in pairs, and stained Gram-negative. Growth was observed between 70 and 97 degrees C (optimum, 85 degrees C; 220 min doubling time), pH 6.5 and 8.8 (optimum, pH 8.0), and salinity of 2.2 and 5.3 % (optimum, 3.5 %). It was a strictly aerobic heterotroph capable of growing on complex proteinaceous substrates such as yeast extract and tryptone. The G+C content of the genomic DNA was 54.4 mol%. Phylogenetic analysis based on the 16S rDNA sequence of the isolate indicated that the isolate was closely related to Aeropyrum pernix strain K1(T). However, no significant genetic relatedness was observed between them by DNA-DNA hybridization. On the basis of the molecular and physiological traits of the new isolate, the name Aeropyrum camini sp. nov. is proposed, with the type strain SY1(T) (=JCM 12091(T)=ATCC BAA-758(T)).  (+info)

Crystal structure of an acylpeptide hydrolase/esterase from Aeropyrum pernix K1. (5/73)

Acylpeptide hydrolases (APH; also known as acylamino acid releasing enzyme) catalyze the removal of an N-acylated amino acid from blocked peptides. The crystal structure of an APH from the thermophilic archaeon Aeropyrum pernix K1 to 2.1 A resolution confirms it to be a member of the prolyl oligopeptidase family of serine proteases. The structure of apAPH is a symmetric homodimer with each subunit comprised of two domains. The N-terminal domain is a regular seven-bladed beta-propeller, while the C-terminal domain has a canonical alpha/beta hydrolase fold and includes the active site and a conserved Ser445-Asp524-His556 catalytic triad. The complex structure of apAPH with an organophosphorus substrate, p-nitrophenyl phosphate, has also been determined. The complex structure unambiguously maps out the substrate binding pocket and provides a basis for substrate recognition by apAPH. A conserved mechanism for protein degradation from archaea to mammals is suggested by the structural features of apAPH.  (+info)

Alteration of product specificity of Aeropyrum pernix farnesylgeranyl diphosphate synthase (Fgs) by directed evolution. (6/73)

Directed evolution of the C25 farnesylgeranyl diphosphate synthase of Aeropyrum pernix (Fgs) was carried out by error-prone PCR with an in vivo color complementation screen utilizing carotenoid biosynthetic pathway enzymes. Screening yielded 12 evolved clones with C20 geranylgeranyl diphosphate synthase activity which were isolated and characterized in order to understand better the chain elongation mechanism of this enzyme. Analysis of these mutants revealed three different mechanisms of product chain length specificity. Two mutants (A64T and A64V) have a single mutation at the 8th amino acid upstream of a conserved first aspartate-rich motif (FARM), which is involved in the mechanism for chain elongation reaction of all prenyl diphosphate synthases. One mutant (A135T) carries a single mutation at the 7th amino acid upstream of another conserved region (141GQ142), which was recently found to be another important region controlling chain elongation of a type III C20 geranylgeranyl diphosphate synthase and Escherichia coli C15 farnesyl diphosphate synthase. Finally, one mutant carrying four mutations (V84I, H88R, I177 M and M191V) is of interest. Molecular modeling, site-directed mutagenesis and in vitro assays of this mutant suggest that product chain-length distribution can be also controlled by a structural change provoked by a cooperative interaction of amino acids.  (+info)

Structure of an XPF endonuclease with and without DNA suggests a model for substrate recognition. (7/73)

The XPF/Mus81 structure-specific endonucleases cleave double-stranded DNA (dsDNA) within asymmetric branched DNA substrates and play an essential role in nucleotide excision repair, recombination and genome integrity. We report the structure of an archaeal XPF homodimer alone and bound to dsDNA. Superposition of these structures reveals a large domain movement upon binding DNA, indicating how the (HhH)(2) domain and the nuclease domain are coupled to allow the recognition of double-stranded/single-stranded DNA junctions. We identify two nonequivalent DNA-binding sites and propose a model in which XPF distorts the 3' flap substrate in order to engage both binding sites and promote strand cleavage. The model rationalises published biochemical data and implies a novel role for the ERCC1 subunit of eukaryotic XPF complexes.  (+info)

Log P effect of organic solvents on a thermophilic alcohol dehydrogenase. (8/73)

An alcohol dehydrogenase from the hyperthermophilic archaeon Aeropyrum pernix was activated by water-miscible organic solvents. This activation was influenced by the kind and the concentration of the added organic solvents. The k(cat) was increased by a factor of over ten when the mole fraction of acetonitrile was 0.1. This effect was large when organic solvents with large log P values were added. In fact, the k(cat) showed a strong positive correlation with the log P value of the mixed solvent at a constant mole fraction of water, while it was not affected by the kind of organic solvents added. Both the activation enthalpy and the entropy decreased with an increase in log P. The contribution of the activation enthalpy to the free energy of activation was larger than that of the activation entropy, and the free energy of activation decreased with an increase in log P.  (+info)

I'm sorry for any confusion, but "Aeropyrum" is not a medical term. It is actually the name of a genus of archaea, which are single-celled microorganisms that lack a nucleus and other membrane-bound organelles. The type species of this genus, Aeropyrum pernix, was first isolated from a marine volcanic area in Japan. This organism is extremophilic, meaning it thrives under extreme conditions, specifically high temperatures.

If you have any medical terms or concepts that you'd like me to explain, please feel free to ask!

Desulfurococcaceae is a family of archaea within the order Desulfurococcales. These organisms are thermophilic, meaning they thrive in high-temperature environments, and are often found in hot springs, deep-sea hydrothermal vents, and other extreme habitats. They are characterized by their ability to grow chemolithotrophically, using sulfur compounds as an energy source. Desulfurococcaceae are also notable for their lack of a cell wall and their unique method of DNA replication, which involves the formation of a circular DNA intermediate.

Here is a medical definition from the US National Library of Medicine:

"A family of archaea within the order Desulfurococcales. The organisms are thermophilic, growing best at temperatures between 65 and 105 degrees Celsius. They are typically found in hot springs, deep-sea hydrothermal vents, and other extreme habitats. They are characterized by their ability to grow chemolithotrophically, using sulfur compounds as an energy source." (Source: MedlinePlus Medical Dictionary)

It's worth noting that while Desulfurococcaceae and other thermophilic archaea are not typically associated with human diseases, they can have important implications for medical research. For example, studying the unique biology of these organisms can provide insights into the fundamental mechanisms of life and help researchers develop new technologies for diagnosing and treating diseases.

Crenarchaeota is a phylum within the domain Archaea. Members of this group are typically extremophiles, living in harsh environments such as hot springs, deep-sea hydrothermal vents, and highly acidic or alkaline habitats. They are characterized by their unique archaeal-type rRNA genes and distinct cell wall composition. Some Crenarchaeota have been found to be involved in nitrogen and carbon cycling in various environments, including the ocean and soil. However, much is still unknown about this group due to the difficulty of culturing many of its members in the lab.

Archaeal proteins are proteins that are encoded by the genes found in archaea, a domain of single-celled microorganisms. These proteins are crucial for various cellular functions and structures in archaea, which are adapted to survive in extreme environments such as high temperatures, high salt concentrations, and low pH levels.

Archaeal proteins share similarities with both bacterial and eukaryotic proteins, but they also have unique features that distinguish them from each other. For example, many archaeal proteins contain unusual amino acids or modifications that are not commonly found in other organisms. Additionally, the three-dimensional structures of some archaeal proteins are distinct from their bacterial and eukaryotic counterparts.

Studying archaeal proteins is important for understanding the biology of these unique organisms and for gaining insights into the evolution of life on Earth. Furthermore, because some archaea can survive in extreme environments, their proteins may have properties that make them useful in industrial and medical applications.

Transfer RNA (tRNA) is a type of RNA molecule that plays a crucial role in protein synthesis in the cell. It carries amino acids to the ribosome, where they are joined together in a specific sequence to form a polypeptide chain, which ultimately becomes a protein.

Each tRNA molecule has a unique structure and is responsible for carrying a specific amino acid. The genetic information that specifies which amino acid a particular tRNA carries is encoded in the form of a three-nucleotide sequence called an anticodon, which is located on one end of the tRNA molecule.

Threonine (Thr) is one of the twenty standard amino acids found in proteins. It is encoded by the codons ACU, ACA, ACC, and ACG in the genetic code. Therefore, a tRNA molecule with an anticodon complementary to any of these codons will carry threonine during protein synthesis.

So, to provide a medical definition of 'RNA, Transfer, Thr', it would be: A type of transfer RNA (tRNA) that carries the amino acid threonine (Thr) to the ribosome during protein synthesis and has an anticodon sequence complementary to one or more of the codons ACU, ACA, ACC, or ACG.

Thermoproteaceae is a family of archaea, a group of single-celled microorganisms that lack a nucleus and are distinct from bacteria and eukaryotes. Thermoproteaceae are part of the order Thermoproteales and belong to the phylum Crenarchaeota. These organisms are extremophiles, meaning they thrive in extreme environments. Specifically, Thermoproteaceae are thermophilic, which means they prefer high temperatures, typically growing optimally between 80-105°C (176-221°F). They are also anaerobic, requiring the absence of oxygen for growth. Some members of this family can also use sulfur compounds as an energy source through a process called sulfur respiration. The cells of Thermoproteaceae are typically rod-shaped or filamentous and may form loose aggregates or mats in their environments.

Archaeal DNA refers to the genetic material present in archaea, a domain of single-celled microorganisms lacking a nucleus. Like bacteria, archaea have a single circular chromosome that contains their genetic information. However, archaeal DNA is significantly different from bacterial and eukaryotic DNA in terms of its structure and composition.

Archaeal DNA is characterized by the presence of unique modifications such as methylation patterns, which help distinguish it from other types of DNA. Additionally, archaea have a distinct set of genes involved in DNA replication, repair, and recombination, many of which are more similar to those found in eukaryotes than bacteria.

One notable feature of archaeal DNA is its resistance to environmental stressors such as extreme temperatures, pH levels, and salt concentrations. This allows archaea to thrive in some of the most inhospitable environments on Earth, including hydrothermal vents, acidic hot springs, and highly saline lakes.

Overall, the study of archaeal DNA has provided valuable insights into the evolutionary history of life on Earth and the unique adaptations that allow these organisms to survive in extreme conditions.

An archaeal genome refers to the complete set of genetic material or DNA present in an archaea, a single-celled microorganism that is found in some of the most extreme environments on Earth. The genome of an archaea contains all the information necessary for its survival, including the instructions for building proteins and other essential molecules, as well as the regulatory elements that control gene expression.

Archaeal genomes are typically circular in structure and range in size from about 0.5 to over 5 million base pairs. They contain genes that are similar to those found in bacteria and eukaryotes, as well as unique genes that are specific to archaea. The study of archaeal genomes has provided valuable insights into the evolutionary history of life on Earth and has helped scientists understand the adaptations that allow these organisms to thrive in such harsh environments.

I'm sorry for any confusion, but the term "hydrothermal vents" is not typically used in medical definitions. Hydrothermal vents are a geological phenomenon found on the ocean floor, where heated water rich in minerals from the Earth's crust escapes into the ocean. They are of interest in various scientific fields, including geology, marine biology, and astrobiology, but they do not have a direct relevance to medical definitions.

Archaea are a domain of single-celled microorganisms that lack membrane-bound nuclei and other organelles. They are characterized by the unique structure of their cell walls, membranes, and ribosomes. Archaea were originally classified as bacteria, but they differ from bacteria in several key ways, including their genetic material and metabolic processes.

Archaea can be found in a wide range of environments, including some of the most extreme habitats on Earth, such as hot springs, deep-sea vents, and highly saline lakes. Some species of Archaea are able to survive in the absence of oxygen, while others require oxygen to live.

Archaea play important roles in global nutrient cycles, including the nitrogen cycle and the carbon cycle. They are also being studied for their potential role in industrial processes, such as the production of biofuels and the treatment of wastewater.

Group II Chaperonins are large, protein-based molecular machines found in the cells of organisms across all domains of life (archaea, bacteria, and eukaryotes). They play a crucial role in facilitating the proper folding of other proteins within the cell. Unlike their Group I counterparts, which are found only in bacteria and archaea, Group II Chaperonins are present in both the cytosol and organelles (such as mitochondria and chloroplasts) of eukaryotic cells.

Group II Chaperonins have a unique structure, forming double-ring complexes composed of multiple subunits. In humans, for example, the Group II Chaperonin known as TCP-1 Ring Complex (TRiC) or CCT (Chaperonin Containing TCP-1) consists of two back-to-back rings, each containing eight different subunits (CCT1-8).

These chaperonins function by encapsulating unfolded proteins within their central cavity. Through ATP-driven conformational changes, they facilitate the folding of these client proteins into their correct three-dimensional structures, thereby preventing protein misfolding and aggregation that can lead to various diseases, including neurodegenerative disorders and cancer.

Archaeal RNA refers to the Ribonucleic acid (RNA) molecules that are present in archaea, which are a domain of single-celled microorganisms. RNA is a nucleic acid that plays a crucial role in various biological processes, such as protein synthesis, gene expression, and regulation of cellular activities.

Archaeal RNAs can be categorized into different types based on their functions, including:

1. Messenger RNA (mRNA): It carries genetic information from DNA to the ribosome, where it is translated into proteins.
2. Transfer RNA (tRNA): It helps in translating the genetic code present in mRNA into specific amino acids during protein synthesis.
3. Ribosomal RNA (rRNA): It is a structural and functional component of ribosomes, where protein synthesis occurs.
4. Non-coding RNA: These are RNAs that do not code for proteins but have regulatory functions in gene expression and other cellular processes.

Archaeal RNAs share similarities with both bacterial and eukaryotic RNAs, but they also possess unique features that distinguish them from the other two domains of life. For example, archaeal rRNAs contain unique sequence motifs and secondary structures that are not found in bacteria or eukaryotes. These differences suggest that archaeal RNAs have evolved to adapt to the extreme environments where many archaea live.

Overall, understanding the structure, function, and evolution of archaeal RNA is essential for gaining insights into the biology of these unique microorganisms and their roles in various cellular processes.

Threonine-tRNA ligase is an enzyme that plays a crucial role in protein synthesis, specifically in the attachment of threonine (Thr) to its corresponding transfer RNA (tRNA). This enzyme catalyzes the formation of a ester bond between the carboxyl group of threonine and the 3'-hydroxyl group of the tRNAThr, creating a charged tRNA molecule that can participate in translation at the ribosome. Proper function of threonine-tRNA ligase is essential for maintaining the fidelity and efficiency of protein synthesis, as it ensures that the correct amino acids are incorporated into proteins according to the genetic code.

Enzyme stability refers to the ability of an enzyme to maintain its structure and function under various environmental conditions, such as temperature, pH, and the presence of denaturants or inhibitors. A stable enzyme retains its activity and conformation over time and across a range of conditions, making it more suitable for industrial and therapeutic applications.

Enzymes can be stabilized through various methods, including chemical modification, immobilization, and protein engineering. Understanding the factors that affect enzyme stability is crucial for optimizing their use in biotechnology, medicine, and research.

Archaeal viruses are viruses that infect and replicate within archaea, which are single-celled microorganisms without a nucleus. These viruses have unique characteristics that distinguish them from bacterial and eukaryotic viruses. They often possess distinct morphologies, such as icosahedral or filamentous shapes, and their genomes can be composed of double-stranded DNA (dsDNA), single-stranded DNA (ssDNA), double-stranded RNA (dsRNA), or single-stranded RNA (ssRNA).

Archaeal viruses have evolved various strategies to hijack the host cell's machinery for replication, packaging, and release of new virus particles. Some archaeal viruses even encode their own proteins for transcription and translation, suggesting a more complex relationship with their hosts than previously thought. The study of archaeal viruses provides valuable insights into the evolution of viruses and their hosts and has implications for understanding the origins of life on Earth.

Proline oxidase is an enzyme that catalyzes the chemical reaction of oxidizing proline to Δ^1^-pyrroline-5-carboxylate (P5C) and hydrogen peroxide (H2O2). The reaction is a part of the catabolic pathway for proline utilization in some organisms.

The systematic name for this enzyme is L-proline:oxygen oxidoreductase (deaminating, decarboxylating). It belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as an acceptor. This enzyme participates in arginine and proline metabolism.
