Carbamoyl-Phosphate Synthase (Ammonia)
Carbamoyl-Phosphate Synthase (Glutamine-Hydrolyzing)
Derivatives of carbamic acid, H2NC(=O)OH. Included under this heading are N-substituted and O-substituted carbamic acids. In general carbamate esters are referred to as urethanes, and polymers that include repeating units of carbamate are referred to as POLYURETHANES. Note however that polyurethanes are derived from the polymerization of ISOCYANATES and the singular term URETHANE refers to the ethyl ester of carbamic acid.
Phosphotransferases (Carboxyl Group Acceptor)
Glutamine-Fructose-6-Phosphate Transaminase (Isomerizing)
Transferases are enzymes transferring a group, for example, the methyl group or a glycosyl group, from one compound (generally regarded as donor) to another compound (generally regarded as acceptor). The classification is based on the scheme "donor:acceptor group transferase". (Enzyme Nomenclature, 1992) EC 2.
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.

Amino Acid Sequence
Carbon-Nitrogen Ligases with Glutamine as Amide-N-Donor
Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p343-4)
Carboxyl and Carbamoyl Transferases
An isomer of glucose that has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379) Inositol phospholipids are important in signal transduction.
The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).
Quaternary Ammonium Compounds
Sequence Homology, Amino Acid
A water-soluble, colorless crystal with an acid taste that is used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters. It is also used in foods as a sequestrant, buffer, and a neutralizing agent. (Hawley's Condensed Chemical Dictionary, 12th ed, p1099; McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1851)
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.

Known to the alchemists1
- As early as the thirteenth century, ammonia was known to the alchemists in the form of sal ammoniac, which was mentioned by Albertus Magnus . (newworldencyclopedia.org)
Excreted by the kidneys1
- Carbamoyl-phosphate is subsequently converted to urea that is excreted by the kidneys. (genscript.com)
- Inhibition of carbamoyl-phosphate synthase (ammonia) by Tris and Hepes. (wikipedia.org)
- S ol volatile , or "smelling salts," are ammonium salts that release ammonia gas, and were frequently used in Victorian England to revive the alarmingly-prevalent swooning woman. (epmonthly.com)
- Household ammonia" or "ammonium hydroxide" is a solution of NH 3 in water. (bionity.com)
- The degree to which ammonia forms the ammonium ion increases upon lowering the pH of the solution- at "physiological" pH (~7), about 99% of the ammonia molecules are protonated. (bionity.com)

- Furthermore, people in the family members encode both carbamoyl phosphate synthase (ECH_0503/ECH_0378) and bifunctional glutamate synthase subunit beta/2-polyprenylphenol hydroxylase (ECH_0778), both which can convert glutamine to ammonia and glutamate (Desk?1). (biomasswars.com)
