| glutamine - phenylpyruvate transaminase | <enzyme> A cysteine conjugate beta-lyase which also carries out transamination of glutamine; without beta-lyase activity use glutamine-pyruvate aminotransferase (EC 2.6.1.15) Registry number: EC 2.6.1.64 Synonym: dichlorovinylcysteine beta-lyase, glutamine transaminase k (26 Jun 1999) |
|---|
| glutamine-fructose-6-phosphate transaminase (isomerizing) | <enzyme> An enzyme that catalyses the synthesis of fructose-6-phosphate plus glutamine from glutamate plus glucosamine-6-phosphate. Chemical name: L-Glutamine:D-fructose-6-phosphate aminotransferase (hexose-isomerizing) Registry number: EC 2.6.1.16 (12 Dec 1998) |
|---|---|
| glutamine transaminase | <enzyme> An enzyme that reversibly converts l-glutamine, alpha-ketoglutaramate, and l-glutamate; alpha-ketoglutaramate is elevated in certain cases of hepatocoma. Synonym: glutamine transaminase. (05 Mar 2000) |
| phenylpyruvate oligophrenia | <disease> Congenital absence of phenylalanine hydroxylase (an enzyme that converts phenylalanine into tyrosine). Phenylalanine accumulates in blood and seriously impairs early neuronal development. The defect can be controlled by diet and is not serious if treated in this way. Incidence: highest in Caucasians. Acronym: PKU Origin: Gr. Ouron = urine (15 Oct 1997) |
| phenylpyruvate oxidase | <enzyme> Phenylpyruvate is converted to o-hydroxyphenyl-acetic acid Registry number: EC 1.- (26 Jun 1999) |
| 3-phenylpyruvate aminotransferase | <enzyme> L-glutamate is amino-donor; forms phenylalanine Registry number: EC 2.6.1.- (26 Jun 1999) |
| carbamoyl-phosphate synthase (glutamine-hydrolyzing) | <enzyme> An enzyme that catalyses the formation of carbamoyl phosphate from ATP, carbon dioxide, and glutamine. This enzyme is important in the de novo biosynthesis of pyrimidines. Chemical name: Carbon dioxide:L-glutamine amido-ligase (ADP-forming, carbamate-phosphorylating) Registry number: EC 6.3.5.5 (12 Dec 1998) |
| carbon-nitrogen ligases with glutamine as amide-n-donor | <enzyme> Enzymes that catalyze the joining of glutamine-derived ammonia and another molecule. The linkage is in the form of a carbon-nitrogen bond. Registry number: EC 6.3.5 (12 Dec 1998) |
| glutamine | <amino acid> One of the 20 amino acids commonly found (and directly coded for) in proteins. It is the amide at the _ carboxyl of the amino acid glutamate. Glutamine can participate in covalent cross linking reactions between proteins, by forming peptide like bonds by a transamidation reaction with lysine residues. This reaction, catalysed by clotting factor XIII stabilises the aggregates of fibrin formed during blood clotting. Media for culture of animal cells contain some 10 times more glutamine than other amino acids, the excess presumably acting as a carbon source. (18 Nov 1997) |
| glutamine amidotransferase | <enzyme> Trpg encodes a glutamine amidotransferase subunit involved in the synthesis of both folic acid and l-tryptophan; this is component II of anthranilate synthase; component I (en to anthranilate synthase) is trpe gene product Registry number: EC 2.6.- Synonym: trpg gene product (26 Jun 1999) |
| glutamine amidotransferase cyclase | <chemical> Possesses glutamine amidotransferase and cyclase activities; his7 isolated from saccharomyces cerevisiae catalyses the fifth and sixth steps of histidine biosynthesis. Synonym: his7 gene product (26 Jun 1999) |
| glutamine aminotransferase | <enzyme> An enzyme that reversibly converts l-glutamine, alpha-ketoglutaramate, and l-glutamate; alpha-ketoglutaramate is elevated in certain cases of hepatocoma. Synonym: glutamine transaminase. (05 Mar 2000) |
| glutamine permease | <chemical> Contains periplasmic glutamine-binding protein plus other membrane-bound proteins Chemical name: permease, glutamine Synonym: gnp1 (saccharomyces cerevisiae) (26 Jun 1999) |
| glutamine-pyruvate aminotransferase | <enzyme> Consider also glutamine transaminase k if cysteine conjugate beta-lyase activity is also present; l-methionine can act as donor; glyoxylate can act as acceptor Registry number: EC 2.6.1.15 Synonym: glutamine alpha-ketoacid transaminase, glutamine transaminase, glutamine transaminase l, glutamine oxo-acid aminotransferase, glutaminase II, glutamine aminotransferase, l-methionine aminotransferase (26 Jun 1999) |
| glutamine synthetase | <enzyme> An enzyme which makes the amino acid glutamine by attaching a molecule of ammonia (NH3) to the amino acid glutamic acid. (09 Oct 1997) |
| protein-glutamine gamma-glutamyltransferase | <enzyme> An enzyme that catalyses the reaction of protein glutamine and an alkylamine to yield protein n(5)-alkylglutamine and ammonia. The gamma-carboxamide groups of peptide-bound glutamine residues act as acyl donors, and the 6-amino groups of protein- and peptide-bound lysine residues act as acceptors, to give intra- and inter-molecular n(6)-(5-glutamyl)lysine crosslinks. In the epidermis these cross-linked proteins are involved in the formation of the cornified envelope of the stratum corneum cells. In the plasma, the transglutaminase is called factor xiiia, the activated form of factor xiii. The crosslinking results in the stabilization of the fibrin clot. Pharmacological action: coagulants. Chemical name: Protein-glutamine:amine gamma-glutamyltransferase Registry number: EC 2.3.2.13 (12 Dec 1998) |
