| phosphoenolpyruvate carboxylase kinase | <enzyme> From bryophyllum fedtschenkoi plant and maise; phosphorylates phosphoenolpyruvate carboxylase on serine near the n-terminus; activity controlled by circadian rhythms Registry number: EC 2.7.10.- Synonym: pep carboxylase kinase, pepc kinase (26 Jun 1999) |

| multiple carboxylase deficiency | Abnormalities in carbohydrate and branched-chain amino acid catabolism that are responsive to biotin therapy. It may be due to deficiency of propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, biotinidase, or propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and pyruvate carboxylase. (12 Dec 1998) |
| polyprenyl-4-hydroxybenzoate carboxylase | <enzyme> Involved in polyprenylphenol synthesis; implicated in flagellation of salmonella typhimurium Registry number: EC 4.1.1.- Synonym: ppphb carboxylase, polyprenyl-p-hydroxybenzoate carboxylase (26 Jun 1999) |
| preprothrombin carboxylase | <enzyme> Vitamin k-dependent, membrane-bound Registry number: EC 4.1.1.- (26 Jun 1999) |
| propionyl-CoA carboxylase | <enzyme> See also propionyl CoA carboxylase (ATP-hydrolyzing) (EC 6.4.1.4) Registry number: EC 4.1.1.41 Synonym: methylmalonyl-CoA decarboxylase, propionyl-coenzyme a carboxylase (26 Jun 1999) |
| pyruvate carboxylase | <enzyme> An enzyme that catalyses the formation of oxaloacetate from pyruvate, carbon dioxide and ATP in gluconeogenesis. (18 Nov 1997) |
| pyruvate carboxylase deficiency | An autosomal recessive pyruvate metabolism disorder resulting from absent or deficient expression of pyruvate carboxylase activity. Decreased production of oxaloacetate leads to decreased gluconeogenesis, thereby causing fasting hypoglycaemia, lactic acid acidosis, and decreased synthesis of amino acid neurotransmitters. Clinical presentations include acidosis, ataxia, mental retardation; sometimes co-occurs with leigh disease. (12 Dec 1998) |
| pyruvic-malic carboxylase | <enzyme> An enzyme that catalyses the conversion of (s)-malate and NAD+ to oxaloacetate and NADH. Chemical name: (S)-Malate:NAD+ oxidoreductase Registry number: EC 1.1.1.37 (12 Dec 1998) |
| oxalosuccinic carboxylase | <enzyme> An enzyme of the oxidoreductase class that catalyses the conversion of isocitrate and NAD+ to yield 2-ketoglutarate, carbon dioxide, and NADH. It occurs in cell mitochondria. The enzyme requires magnesium, mn2+; it is activated by ADP, citrate, and calcium, and inhibited by NADH, NADPH, and ATP. The reaction is the key rate-limiting step of the citric acid (tricarboxylic) cycle. (the NADP+ enzyme is EC 1.1.1.42.) Chemical name: Isocitrate:NAD+ oxidoreductase (decarboxylating) Registry number: EC 1.1.1.41 (12 Dec 1998) |
