Meso-tartrate dehydrogenase

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