| 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) |

| 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) |
| acetoacetyl-CoA synthetase | <enzyme> Catalyses the conversion of acetoacetate and CoA in the presence of ATP to yield AMP, pyrophosphate and acetoacetyl-CoA; the latter is the first intermediate in cholesterogenesis; also acts more slowly on l-3-hydroxybutanoate Registry number: EC 6.2.1.16 Synonym: acetoacetyl-CoA ligase, acetoacetate-CoA ligase, acetoacetyl-coenzyme a synthetase (26 Jun 1999) |
| acetyl-CoA synthetase | A ligase that catalyses the reaction of acetate and CoA and ATP to form AMP, pyrophosphate, and acetyl-CoA. A key step in the activation of acetate. Synonym: acetate thiokinase, acetate-CoA ligase, acetyl-activating enzyme, acetyl-CoA synthetase. (05 Mar 2000) |
