[10] While under standard conditions malate cannot reduce the more electronegative NAD +:NADH couple, in the cell the concentration of oxaloacetate is kept low enough that Malate dehydrogenase can reduce NAD + to NADH during the citric acid cycle. Fumarate + 2 H + + 2 e − → Succinate +0.03 [9] O 2 + 2H + + 2e − → H 2 O 2 +0.30
Members of this family include oxygen-insensitive NAD(P)H nitroreductase (flavin mononucleotide-dependent nitroreductase) (6,7-dihydropteridine reductase) (EC 1.5.1.34) and NADH dehydrogenase (EC 1.6.99.3). A number of these proteins are described as oxidoreductases.
Biosensors used for screening combinatorial DNA libraries. In a biosensor, the bioreceptor is designed to interact with the specific analyte of interest to produce an effect measurable by the transducer. High selectivity for the analyte among a matrix of other chemical or biological components is a key requirement of the bioreceptor.
Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...
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 rat liver, the total amount of NAD + and NADH is approximately 1 μmole per gram of wet weight, about 10 times the concentration of NADP + and NADPH in the same cells. [17] The actual concentration of NAD + in cell cytosol is harder to measure, with recent estimates in animal cells ranging around 0.3 mM , [ 18 ] [ 19 ] and approximately 1.0 ...
In enzymology, a nitrite reductase [NAD(P)H] (EC 1.7.1.4) is an enzyme that catalyzes the chemical reaction. ammonium hydroxide + 3 NAD(P) + + H 2 O nitrite + 3 NAD(P)H + 3 H + The 4 substrates of this enzyme are ammonium hydroxide, NAD +, NADP +, and H 2 O, whereas its 4 products are nitrite, NADH, NADPH, and H +.
