The midpoint potential of the NAD + /NADH redox pair is −0.32 volts, which makes NADH a moderately strong reducing agent. [7] The reaction is easily reversible, when NADH reduces another molecule and is re-oxidized to NAD +. This means the coenzyme can continuously cycle between the NAD + and NADH forms without being consumed. [5]
In enzymology, a glutamate synthase (NADH) (EC 1.4.1.14) is an enzyme that catalyzes the chemical reaction. 2 L-glutamate + NAD + L-glutamine + 2-oxoglutarate + NADH + H + Glutamate synthase facilitates the ammonium assimilation pathway, which follows the enzymes, nitrite reductase and glutamine synthase. [1]
This category groups enzymes that use nicotinamide adenine dinucleotide (NAD + and its reduced form, NADH) in redox reactions. See also Category:NADPH-dependent enzymes.. In general, the NAD is not stably associated with the enzyme, being a coenzyme; hence, we call such enzymes "NADH-dependent" enzymes, rather than simply "NADH enzymes".
Other names in common use include NAD+ pyrophosphorylase, adenosine triphosphate-nicotinamide mononucleotide transadenylase, ATP:NMN adenylyltransferase, diphosphopyridine nucleotide pyrophosphorylase, nicotinamide adenine dinucleotide pyrophosphorylase, nicotinamide mononucleotide adenylyltransferase, and NMN adenylyltransferase.
[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
In enzymology, a NAD + synthetase (EC 6.3.1.5) is an enzyme that catalyzes the chemical reaction ATP + deamido-NAD + + NH 3 ⇌ {\displaystyle \rightleftharpoons } AMP + diphosphate + NAD + The 3 substrates of this enzyme are ATP , deamido-NAD + , and NH 3 , whereas its 3 products are AMP , diphosphate , and NAD + .
an aldehyde + NAD + + H 2 O an acid + NADH + H + The 3 substrates of this enzyme are aldehyde, NAD +, and H 2 O, whereas its 3 products are acid, NADH, and H +. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor.
In enzymology, a NAD + diphosphatase (EC 3.6.1.22) is an enzyme that catalyzes the chemical reaction NAD + + H 2 O ⇌ {\displaystyle \rightleftharpoons } AMP + NMN Thus, the two substrates of this enzyme are NAD + and H 2 O , whereas its two products are AMP and NMN .
