 Dimethylmalate dehydrogenase

In enzymology, a dimethylmalate dehydrogenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are (R)-3,3-dimethylmalate and NAD+, whereas its 3 products are 3-methyl-2-oxobutanoate, CO2, and NADH.This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
