| AGT | Alanine-Glyoxylate Aminotransferase |
|---|
| glyoxylate aminotransferase | <enzyme> Various amino acids can serve as amino donors; with serine it is EC 2.6.1.45; best donors for rat liver and kidney enzyme are leucine and phenylalanine Registry number: EC 2.6.1.- (26 Jun 1999) |
|---|---|
| glyoxylate cycle | <biochemistry> Metabolic pathway present in bacteria and in the glyoxisome of plants, in which two acetyl CoA molecules are converted to a 4 carbon dicarboxylic acid, initially succinate. Includes two enzymes not found elsewhere, isocitrate lyase and malate synthase. Permits net synthesis of carbohydrates from lipid and hence is prominent in those seeds in which lipid is the principal food reserve. (18 Nov 1997) |
| glyoxylate synthetase | <enzyme> Catalyses the condensation of two formate molecules into glyoxylate; a tetramer with mw of 160 kD with a subunit mw of 40 kD; isolated from green potato-tuber chloroplasts Registry number: EC 4.1.3.- (26 Jun 1999) |
| glyoxylate transacetylase | <enzyme> An important enzyme in the glyoxylic acid cycle which reversibly catalyses the synthesis of l-malate from acetyl-CoA and glyoxylate. Chemical name: L-Malate glyoxylate-lyase (CoA-acetylating) Registry number: EC 4.1.3.2 (12 Dec 1998) |
| alanine-glyoxylate aminotransferase | <enzyme> Do not confuse with serine-pyruvate aminotransferase (EC 2.6.1.51), even though they may be products of the same gene; index whichever is discussed or both Registry number: EC 2.6.1.44 Synonym: pyruvate (glyoxylate) aminotransferase, kynurenine-glyoxylate aminotransferase, alanine-glyoxylate aminotransferase 1,dimethylarginine pyruvate aminotransferase, alanine-glyoxylate transaminase 1,alanine-glyoxylate aminotransferase 2 (26 Jun 1999) |
|---|---|
| serine-glyoxylate aminotransferase | <enzyme> Pea enzyme; also uses asparagine as amino donor with either pyruvate or glyoxylate as acceptor Registry number: EC 2.6.1.45 Synonym: asparagine aminotransferase (26 Jun 1999) |
Synonyms :
| glyoxylate |
a salt, anion, or ester of glyoxylic acid.

|---|---|
| glyoxylate c. |
a metabolic pathway by which certain microorganisms and plants convert fat to carbohydrate; its enzymes are contained in microbodies known as glyoxosomes. It is a modification of the tricarboxylic acid cycle but differs in that two auxiliary enzymes (isocitratase and malate synthetase) are used and two molecules of acetyl coenzyme A instead of one are required.
