| myo-inositol-1-phosphate dehydrogenase | <enzyme> Requires nad+, forms ribulose 5-phosphate Registry number: EC 1.1.1.- Synonym: inositol-1-phosphate dehydrogenase (26 Jun 1999) |
|---|---|
| prephenate dehydrogenase | <enzyme> An enzyme that catalyses the conversion of prephenate to p-hydroxyphenylpyruvate in the presence of NAD. In the enteric bacteria, this enzyme also possesses chorismate mutase activity, thereby catalyzing the first two steps in the biosynthesis of tyrosine. Chemical name: Prephenate:NAD+ oxidoreductase (decarboxylating) Registry number: EC 1.3.1.12 (12 Dec 1998) |
| prephytoene pyrophosphate dehydrogenase | <enzyme> Encoded by gene crte; reaction product of above enzyme is a phytoene; gene found in the cyanella (plastid) DNA of an eukaryotic alga, cyanophora paradoxa; amino acid sequence given in first source Registry number: EC 1.- Synonym: ppp-dehydrogenase, crte gene product, geranylgeranyl pyrophosphate synthase, geranylgeranyl-pyrophosphate synthase, albino-3 gene product (26 Jun 1999) |
| sabinol dehydrogenase | <enzyme> Enzyme from sage (salvia officinalis) and tansy (tana cetum vulgare) converts (+)-cis-sabinol to (+)-sabinone Registry number: EC 1.1.1.- (26 Jun 1999) |
| saccharopine dehydrogenase | Two enzymes that are used in the pathway of l-lysine catabolism; the first isoform catalyses the reversible conversion of l-lysine, alpha-ketoglutarate, and NADH to saccharopine and NAD+; the other isoform reversibly catalyses to conversion of saccharopine and NAD+ to l-glutamate, NADH, and l-alpha-aminoadipate d-saemialdehyde. A deficiency of one of these isoforms is associated with familial hyperlysinaemia and saccharopinuria. (05 Mar 2000) |
| proline dehydrogenase | An oxidoreductase reducing 1-pyrroline-2-carboxylate to l-proline with NAD(P)H. Synonym: proline dehydrogenase, proline oxidase. (05 Mar 2000) |
| sarcosine dehydrogenase | <enzyme> An enzyme that cleaves sarcosine using some acceptor to produce glycine, formaldehyde, and a reduced acceptor molecule; a deficiency of this enzyme will result in sarcosinaemia. (05 Mar 2000) |
| xanthine dehydrogenase | <enzyme> An enzyme that catalyses the oxidation of xanthine in the presence of NAD+ to form urate and NADH. It acts also on a variety of other purines and aldehydes. Chemical name: Xanthine:NAD+ oxidoreductase Registry number: EC 1.1.1.204 (12 Dec 1998) |
| xylitol 5-phosphate dehydrogenase | <enzyme> Forms xylulose 5-phosphate Registry number: EC 1.1.1.- (26 Jun 1999) |
| xylitol dehydrogenase | <enzyme> An enzyme that reversibly converts xylulose to xylitol using either NADH (d-xylulose reductase) or NADPH (l-xylulose reductase); a deficiency of the l-form is seen in individuals with essential pentosuria. Synonym: xylitol dehydrogenase. (05 Mar 2000) |
| homoserine dehydrogenase | <enzyme> An enzyme that catalyses the reduction of aspartic beta-saemialdehyde to homoserine, which is the branch point in biosynthesis of methionine, lysine, threonine and leucine from aspartic acid. Chemical name: L-Homoserine:NAD(P)+ oxidoreductase Registry number: EC 1.1.1.3 (12 Dec 1998) |
| pyridoxine 4-dehydrogenase | <enzyme> Chemical name: dehydrogenase, pyridoxol 4- Registry number: EC 1.1.1.65 Synonym: pyridoxine phosphate dehydrogenase, pyridoxal reductase (26 Jun 1999) |
| pyruvate dehydrogenase | <enzyme> A complex multienzyme system that catalyses the conversion of (pyruvate + CoA + NAD) to (acetyl CoA + CO2 + NAD). (18 Nov 1997) |
| pyruvate dehydrogenase complex | <enzyme> A complex multienzyme system that catalyses the conversion of (pyruvate + CoA + NAD) to (acetyl CoA + CO2 + NAD). (18 Nov 1997) |
| pyruvate dehydrogenase complex deficiency | An autosomal recessive pyruvate metabolism disorder resulting from deficient enzyme activity in one of several proteins of pyruvate dehydrogenase complex, resulting in deficiency of acetyl CoA. Deficiency in acetyl CoA product reduces the synthesis of acetylcholine, thereby causing neurological abnormalities. Clinical presentations include lactic acidosis, mental retardation, and ataxia.
