Eggerthellales
The ''Eggerthellaceae'' are a family of Gram-positive, rod- or coccus-shaped Actinomycetota. It is the sole family within the order ''Eggerthellales.'' The name ''Eggerthellaceae'' is derived from the Latin term ''Eggerthella,'' referring to the type genus of the family and the suffix "-ceae," an ending used to denote a family. Together, ''Eggerthellaceae'' refers to a family whose nomenclatural type is the genus ''Eggerthella''. Biochemical characteristics and molecular signatures Members of this family are mostly anaerobic, non-motile (with the exception of some ''Gordonibacter'' and ''Senegalimassilia'' species that exhibit motility), asaccharolytic and do not form spores. ''Eggerthellaceae'' species are commonly isolated from human and animal faeces and other human sources such as the colon, vagina, oral cavity and blood. Some species have also been isolated from human samples of periodontal or endodontic infections, Crohn's disease and severe blood bacteremia. The G+C co ...

Denitrobacterium
''Denitrobacterium'' is a genus of Actinomycetota with a single species, in the family Coriobacteriaceae. Originally isolated from the bovine rumen, ''Denitrobacterium'' are non-motile and non-spore forming. The only described species in this genus is ''Denitrobacterium detoxificans''. The specific niche of this bacterium in the bovine rumen is theorized to be the detoxification/metabolism of nitrotoxins and miserotoxin. Characteristics of ''Denitrobacterium detoxificans'' The sole species currently described in the genus ''Denitrobacterium'', ''D. detoxificans'', is a Gram-positive, obligate anaerobe. In the study conducted by Anderson ''et al''., all of the four strains (NPOH1, NPOH2, NPOH3, and MAJ1) are shown to possess high G+C content in their DNAs (60, 58, 56, and 60 mol%, respectively) and are closely related to one another (more than 99% sequence identity). Additionally, the closest intergeneric relative is ''Coriobacterium glomerans'' with 86% sequence identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outgroup (cladistics)
In cladistics or phylogenetics, an outgroup is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study, and is distinct from sociological outgroups. The outgroup is used as a point of comparison for the ingroup and specifically allows for the phylogeny to be rooted. Because the polarity (direction) of character change can be determined only on a rooted phylogeny, the choice of outgroup is essential for understanding the evolution of traits along a phylogeny. History Although the concept of outgroups has been in use from the earliest days of cladistics, the term "outgroup" is thought to have been coined in the early 1970s at the American Museum of Natural History. Prior to the advent of the term, various other terms were used by evolutionary biologists, including "exgroup", "related group", and "outside groups". Choice of outgroup The chosen outgroup is hypothe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA-directed RNA Polymerase
A polymerase is an enzyme (Enzyme Commission number, EC 2.7.7.6/7/19/48/49) that synthesizes long chains of polymers or nucleic acids. DNA polymerase and RNA polymerase are used to assemble DNA and RNA molecules, respectively, by copying a DNA template strand using Base pair, base-pairing interactions or RNA by half ladder replication. A DNA polymerase from the thermophile, thermophilic bacteria, bacterium, ''Thermus aquaticus'' (''Taq'') (Protein Data Bank, PDB]1BGX EC 2.7.7.7) is used in the polymerase chain reaction, an important technique of molecular biology. A polymerase may be template dependent or template independent. Polynucleotide adenylyltransferase, Poly-A-polymerase is an example of template independent polymerase. Terminal deoxynucleotidyl transferase also known to have template independent and template dependent activities.

UDP-glucose 4-epimerase
The enzyme UDP-glucose 4-epimerase (), also known as UDP-galactose 4-epimerase or GALE, is a homodimeric epimerase found in bacterial, fungal, plant, and mammalian cells. This enzyme performs the final step in the Leloir pathway of galactose metabolism, catalyzing the reversible conversion of UDP-galactose to UDP-glucose. GALE tightly binds nicotinamide adenine dinucleotide (NAD+), a co-factor required for catalytic activity. Additionally, human and some bacterial GALE isoforms reversibly catalyze the formation of UDP-''N''-acetylgalactosamine (UDP-GalNAc) from UDP-''N''-acetylglucosamine (UDP-GlcNAc) in the presence of NAD+, an initial step in glycoprotein or glycolipid synthesis. Historical significance Dr. Luis Leloir deduced the role of GALE in galactose metabolism during his tenure at the Instituto de Investigaciones Bioquímicas del Fundación Campomar, initially terming the enzyme waldenase. Dr. Leloir was awarded the 1970 Nobel Prize in Chemistry for his discover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
