Solibacillus
''Solibacillus'' is a genus of Gram positive, rod shaped, spore-forming bacteria. The first member of ''Solibacillus'' was first isolated in 1999, and was originally called ''Bacillus silvestris''. However, further studies on ''B. silvestris'' found that the organism belonged in a separate genus. ''Solibacillus silvestris'' was proposed, referring to its original designation as a member of ''Bacillus'', and the fact that the species was first isolated from soil. ''Bacillus isronensis'' was later reclassified as ''Solibacillus isronensis''. ''S. isronensis'' was isolated from cryotubes that were used to collect air samples from high altitudes, and ''S. kalamii'' was found in an air filter from the International Space Station.Sielaff AC, Kumar RM, Pal D, Mayilraj S, Venkateswaran K.

Caryophanaceae
The ''Caryophanaceae'' is a family of Gram-positive bacteria. In 2020, the now defunct family '' Planococcaceae'' was merged into ''Caryophanaceae'' to rectify a nomenclature anomaly. The type genus of this family is ''Caryophanon.'' The family ''Planococcacae'' was validly published in 1949, however it contained within it another family level taxonomic rank, the family ''Caryophanaceae,'' which was validly published in 1939. According to the International Code of Nomenclature of Prokaryotes (ICNP), the name ''Caryophanacaeae'' has higher priority than ''Planococcaceae'' because of its earlier publication. Therefore, the emended family retained the name ''Caryophanaceae''. The name ''Caryophanaceae'' is derived from the Latin term ''Caryophanon'', referring the type genus of the family and the suffix "-aceae", an ending used to denote a family. Together, ''Caryophanaceae'' refers to a family whose nomenclatural type is the genus ''Caryophanon''. Biochemical Characteristics an ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulp ...

International Code Of Nomenclature Of Prokaryotes
The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P. H. A. Sneath, 2003. A short history of the Bacteriological CodURL It denotes the rules for naming taxa of bacteria, according to their relative rank. As such it is one of the nomenclature codes of biology. Originally the ''International Code of Botanical Nomenclature'' dealt with bacteria, and this kept references to bacteria until these were eliminated at the 1975 International Botanical Congress. An early Code for the nomenclature of bacteria was approved at the 4th International Congress for Microbiology in 1947, but was later discarded. The latest version to be printed in book form is the 1990 Revision, but the book does not represent the current rules. The 2008 Revision has been published in the ''International Journal of Systematic and Evolutionary Microbiology'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATPase
ATPases (, Adenosine 5'-TriPhosphatase, adenylpyrophosphatase, ATP monophosphatase, triphosphatase, SV40 T-antigen, ATP hydrolase, complex V (mitochondrial electron transport), (Ca2+ + Mg2+)-ATPase, HCO3−-ATPase, adenosine triphosphatase) are a class of enzymes that catalyze the decomposition of ATP into ADP and a free phosphate ion or the inverse reaction. This dephosphorylation reaction releases energy, which the enzyme (in most cases) harnesses to drive other chemical reactions that would not otherwise occur. This process is widely used in all known forms of life. Some such enzymes are integral membrane proteins (anchored within biological membranes), and move solutes across the membrane, typically against their concentration gradient. These are called transmembrane ATPases. Functions Transmembrane ATPases import metabolites necessary for cell metabolism and export toxins, wastes, and solutes that can hinder cellular processes. An important example is the sodium-po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peroxidase
Peroxidases or peroxide reductases ( EC numberbr>1.11.1.x are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides. Functionality Peroxidases typically catalyze a reaction of the form: :ROOR' + \overset + 2H+ -> ce + R'OH Optimal substrates For many of these enzymes the optimal substrate is hydrogen peroxide, but others are more active with organic hydroperoxides such as lipid peroxides. Peroxidases can contain a heme cofactor in their active sites, or alternately redox-active cysteine or selenocysteine residues. The nature of the electron donor is very dependent on the structure of the enzyme. * For example, horseradish peroxidase can use a variety of organic compounds as electron donors and acceptors. Horseradish peroxidase has an accessible active site, and many compounds can reach the site of the reaction. * On the other hand, for an enzyme such as cytochrome c peroxidase, the com ...

Dna Topoisomerase Iv
Topoisomerase IV is one of two Type II topoisomerases in bacteria, the other being DNA gyrase. Like gyrase, topoisomerase IV is able to pass one double-strand of DNA through another double-strand of DNA, thereby changing the linking number of DNA by two in each enzymatic step. Both share a hetero-4-mer structure formed by a symmetric homodimer of A/B heterodimers, usually named ''ParC'' and ''ParE''. Functions Topoisomerase IV has two functions in the cell. * First, it is responsible for unlinking, or decatenating, DNA following DNA replication. The double-helical nature of DNA and its semiconservative mode of replication causes the two newly replicated DNA strands to be interlinked. These links must be removed in order for the chromosome (and plasmids) to segregate into daughter cells so that cell division can complete. * Topoisomerase IV's second function in the cell is to relax positive supercoils. It shares this role with DNA gyrase, which is also able to relax positive superco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aminodeoxychorismate Lyase
4-amino-4-deoxychorismate lyase () is an enzyme that participates in folate biosynthesis by catalyzing the production of PABA by the following reaction :4-amino-4-deoxychorismate \rightleftharpoons 4-aminobenzoate + pyruvate This enzyme belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. This enzyme, encoded by the ''pabC'' gene in bacteria and plants, is also known as PabC or ADC lyase. The fungal enzyme has been designated ABZ2. All known examples of 4-amino-4-deoxychorismate lyase bind PLP (pyridoxal-5'-phosphate Pyridoxal phosphate (PLP, pyridoxal 5'-phosphate, P5P), the active form of vitamin B6, is a coenzyme in a variety of enzymatic reactions.

Conserved Signature Indels
Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. CSIs, brought about by rare genetic changes, provide useful phylogenetic markers that are generally of defined size and they are flanked on both sides by conserved regions to ensure their reliability. While indels can be arbitrary inserts or deletions, CSIs are defined as only those protein indels that are present within conserved regions of the protein. The CSIs that are restricted to a particular clade or group of species, generally provide good phylogenetic markers of common evolutionary descent. Due to the rarity and highly specific nature of such changes, it is less likely that they could arise independently by either convergent or parallel evolution (i.e. homoplasy) and therefore are likely to represent synapomorphy. Other confounding factors such as differences in evolutionary rates at different sites or amon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
