In enzymology, tartrate dehydrogenase (EC 1.1.1.93) is an enzyme that catalyzes the chemical reaction

H+
Tartrate dehydrogenase
 
H+
 
+ NADH
 

The two substrates of this enzyme are meso-tartaric acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 2-hydroxy-3-oxosuccinic acid, reduced NADH, and a proton. The enzyme can also act on the stereoisomer (+)-tartaric acid, giving the same product. [1] [2]

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 tartrate:NAD+ oxidoreductase. This enzyme is also called mesotartrate dehydrogenase. This enzyme participates in glyoxylate and dicarboxylate metabolism. It employs one cofactor, manganese.
