2 hydroxymethylglutarate dehydrogenase

In enzymology, a 2-hydroxymethylglutarate dehydrogenase (EC 1.1.1.291) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are (S)-2-hydroxymethylglutarate and NAD⁺, whereas its 3 products are 2-formylglutarate, NADH, and H⁺.

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 (S)-2-hydroxymethylglutarate:NAD⁺ oxidoreductase. This enzyme is also called HgD.
