Meso tartrate dehydrogenase

In enzymology, a meso-tartrate dehydrogenase (EC 1.3.1.7) is an enzyme that catalyzes the chemical reaction

meso-tartrate + NAD⁺ ⇌ dihydroxyfumarate + NADH + H⁺

Thus, the two substrates of this enzyme are meso-tartaric acid and NAD⁺, whereas its 3 products are dihydroxyfumarate, NADH, and H⁺.

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.
