| cytochrome c2 reductase | <enzyme> An enzyme catalyzing the reduction of 2 ferricytochrome c2 to 2 ferrocytochrome c2 at the expense of NADPH. Synonym: cytochrome c2 reductase. (05 Mar 2000) |
|---|---|
| cytochrome c reductase | <enzyme> A flavoprotein containing iron. Cytochrome c may act as receptor. The enzyme reversibly catalyses the oxidation of NADH to NAD and reduced acceptor. An inherited deficiency of this complex results in overwhelming acidosis. Synonym: cytochrome c reductase. Chemical name: NADH:(acceptor) oxidoreductase Registry number: EC 1.6.99.3 (12 Dec 1998) |
| cytochrome reductase | <enzyme> A flavoprotein that catalyses the reduction of haem-thiolate-dependent monooxygenases and is part of the microsomal hydroxylating system. Its physiological acceptor is probably cytochrome p-450. Chemical name: NADPH:ferrihemoprotein oxidoreductase Registry number: EC 1.6.2.4 (12 Dec 1998) |
| HC toxin reductase | <enzyme> Nadph-dependent enzyme from maise which inactivates the cyclic tetrapeptide, hc toxin, from cochliobolus carbonum; amino acid sequence given in first source Registry number: EC 1.- Synonym: hm1 gene product (26 Jun 1999) |
| progesterone 20-keto-reductase | <enzyme> Rat liver microsome enzyme requires NADPH to form the 20beta alcohol, also forms 20alpha oh using NADH Registry number: EC 1.1.1.- Synonym: progesterone 20-reductase, progesterone 20-beta reductase (26 Jun 1999) |
| progesterone 5 alpha-reductase | <enzyme> Do not confuse this with progesterone reductase which is a 3 beta-hydroxysteroid dehydrogenase Registry number: EC 1.3.1.30 (26 Jun 1999) |
| progesterone 5 beta-reductase | <enzyme> A stereospecific enzyme; forms 5 beta-pregnane-3,20-dione from progesterone; see also progesterone 5 alpha-reductase Registry number: EC 1.3.1.- (26 Jun 1999) |
| progesterone reductase | <enzyme> An enzyme that catalyses the reduction of a 3 beta-hydroxy-delta(5)-steroid to 3-oxo-delta(4)-steroid in the presence of NAD. It converts pregnenolone to progesterone and dehydroepiandrosterone to androstenedione.45. Chemical name: 3 beta-Hydroxy-delta(5)-steroid:NAD+ 3-oxidoreductase Registry number: EC 1.1.1.145 (12 Dec 1998) |
| sarcosine reductase | <enzyme> Involved in sarcosine metabolism in eubacterium acidaminophilum Registry number: EC 1.4.4.- Synonym: n-methylglycine reductase (26 Jun 1999) |
| prostaglandin-E2 9-reductase | <enzyme> Catalyses reversibly an nad+ dependent oxidation of the 9alpha-hydroxyl group of 15-keto-13,14-dihydro-pgf2alpha to 15-keto-13,14-dihydro-pge2; also acts on pga1; sequence data indicates that it is identical with carbonyl reductase (NADPH) (EC 1.1.1.184) Registry number: EC 1.1.1.189 Synonym: 9-ketoprostaglandin reductase, prostaglandin-9-hydroxydehydrogenase, pge2 9-ketoreductase, pge 9-ketoreductase, prostaglandin e2-9-oxoreductase, prostaglandin 9-ketoreductase, prostaglandin e2-9-ketoreductase, 9-hydroxy-pg dehydrogenase, 9-hydroxyprostaglandin dehydrogenase, pge2 9-reductase (26 Jun 1999) |
| protein disulfide reductase (glutathione) | <enzyme> An enzyme that catalyses the reduction of a protein-disulfide in the presence of glutathione, forming a protein-dithiol. Insulin is one of its substrates. Chemical name: Glutathione:protein-disulfide oxidoreductase Registry number: EC 1.8.4.2 (12 Dec 1998) |
| heterodisulfide reductase | <enzyme> A two-subunit cytochrome b-containing enzyme from methanol-grown methanosarcina barkeri; catalyses the terminal step in the energy-conserving electron transport chain in methanogenic archaea; has been sequenced; authors give EC number as 1.99.4.- (not in enzyme nomenclature) Registry number: EC 1.12.99.- (26 Jun 1999) |
| xylulose reductase | <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) |
