| 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 inactivase | <enzyme> Pharmacological action: enzyme inhibitor Registry number: EC 3.4.- (26 Jun 1999) |
| pyruvate dehydrogenase (cytochrome) | An oxidoreductase catalyzing reaction between ferricytochrome b1 and pyruvate to yield acetate and CO2, and ferrocytochrome b1. (05 Mar 2000) |
| pyruvate dehydrogenase (lipoamide) | An oxidoreductase catalyzing conversion of pyruvate and (oxidised) lipoamide to CO2 and S6-acetyldihydrolipoamide in two successive reactions: the first between pyruvate and thiamin pyrophosphate to yield CO2 and alpha-hydroxyethylthiamin pyrophosphate (active pyruvate); the second between the last named and lipoamide to regain the thiamin pyrophosphate and yield S6-acetylhydrolipoamide. Compare: alpha-ketodecarboxylase. (05 Mar 2000) |
