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

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

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

<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)

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.
