Paenarthrobacter Histidinolovorans
''Paenarthrobacter histidinolovorans'' is a bacterium species from the genus ''Paenarthrobacter'' which has been isolated from soil. ''Paenarthrobacter histidinolovorans'' produces histidinol dehydrogenase In enzymology, histidinol dehydrogenase (HIS4) (HDH) () is an enzyme that catalyzes the chemical reaction :L-histidinol + 2 NAD+ \rightleftharpoons L-histidine + 2 NADH + 2 H+ Thus, the two substrates of this enzyme are L-histidinol and NAD ....

Paenarthrobacter
''Paenarthrobacter'' is a genus of bacteria from the family Micrococcaceae. ''Paenarthrobacter'' members share the following properties: * A3a type peptidoglycan * Menaquinone MK-9(H2) * A polar lipid profile composed primarily of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, dimannosylglyceride, and monogalactosyldiacylglycerol; and to a lesser extent, trimannosyldiacylglycerol. * A fatty acid composition primarily from anteiso-C15:0, and to a lesser extent iso-C15:0, iso-C16:0, anteiso-C17:0 and isoC14. * A genomic GC content In molecular biology and genetics, GC-content (or guanine-cytosine content) is the percentage of nitrogenous bases in a DNA or RNA molecule that are either guanine (G) or cytosine (C). This measure indicates the proportion of G and C bases out o ... in the range of 61.3–62.5 mol%. References External links * {{Taxonbar, from=Q27438445 Micrococcaceae ...

Histidinol Dehydrogenase
In enzymology, histidinol dehydrogenase (HIS4) (HDH) () is an enzyme that catalyzes the chemical reaction :L-histidinol + 2 NAD+ \rightleftharpoons L-histidine + 2 NADH + 2 H+ Thus, the two substrates of this enzyme are L-histidinol and NAD+, whereas its 3 products are L-histidine, NADH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-histidinol:NAD+ oxidoreductase. This enzyme is also called L-histidinol dehydrogenase. Histidinol dehydrogenase catalyzes the terminal step in the biosynthesis of histidine in bacteria, fungi, and plants, the four-electron oxidation of L-histidinol to histidine. In 4-electron dehydrogenases, a single active site catalyses 2 separate oxidation steps: oxidation of the substrate alcohol to an intermediate aldehyde; and oxidation of the aldehyde to the product acid, in this case His.

Bacteria Described In 1954
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large 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, 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 fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of 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 sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationships wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
