NADH dehydrogenase is used in the electron transport chain for generation of ATP. The EC term NADH dehydrogenase (quinone) (EC 1.6.5.11) is defined for NADH dehydrogenases that use a quinone (excluding ubiquinone) as the acceptor. The EC term NADH dehydrogenase (ubiquinone) (EC 7.1.1.2) is defined for those with ubiquinone as the acceptor.
Thus, the two substrates of this enzyme are L-glutamate and NAD +, whereas its 4 products are L-glutamine, 2-oxoglutarate, NADH, and H +. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH 2 group of donors with NAD + or NADP + as acceptor. This enzyme participates in glutamate metabolism and nitrogen ...
In enzymology, a hydroxylamine reductase (NADH) (EC 1.7.1.10) is an enzyme that catalyzes the chemical reaction.. NH 3 + NAD + + H 2 O hydroxylamine + NADH + H +. The 3 substrates of this enzyme are NH 3, NAD +, and H 2 O, whereas its 3 products are hydroxylamine, NADH, and H +.
For example, an enzyme that catalyzed this reaction would be an oxidoreductase: A – + B → A + B –. In this example, A is the reductant (electron donor) and B is the oxidant (electron acceptor).
The effects of the NAD + /NADH ratio are complex, controlling the activity of several key enzymes, including glyceraldehyde 3-phosphate dehydrogenase and pyruvate dehydrogenase. In healthy mammalian tissues, estimates of the ratio of free NAD + to NADH in the cytoplasm typically lie around 700:1; the ratio is thus favorable for oxidative reactions.
The 3 substrates of this enzyme are NADH, H +, and monodehydroascorbate, whereas its two products are NAD + and ascorbate. This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH, with a quinone or similar compound as an acceptor. The systematic name of this enzyme class is NADH: monodehydroascorbate ...
Enzymatic reaction catalyzed by NDH-2. In yellow is represented the protein surface, sitting in the membrane (in gray) NDH-2, also known as type II NADH:quinone oxidoreductase or alternative NADH dehydrogenase, is an enzyme (EC: 1.6.99.3) which catalyzes the electron transfer from NADH (electron donor) to a quinone (electron acceptor), being part of the electron transport chain.

In enzymology, a NADH peroxidase (EC 1.11.1.1) is an enzyme that catalyzes the chemical reaction. NADH + H + + H 2 O 2 NAD + + 2 H 2 O. The presumed function of NADH peroxidase is to inactivate H 2 O 2 generated within the cell, for example by glycerol-3-phosphate oxidase during glycerol metabolism or dismutation of superoxide, before the H 2 O 2 causes damage to essential cellular components.
