Hydroxymalonate dehydrogenase

In enzymology, a hydroxymalonate dehydrogenase is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are tartronic acid and oxidised nicotinamide adenine dinucleotide. Its products are mesoxalic acid, reduced NADH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is hydroxymalonate:NAD⁺ oxidoreductase.
