EC 1.1.1.37     
Accepted name: malate dehydrogenase
Reaction: (S)-malate + NAD+ = oxaloacetate + NADH + H+
Other name(s): malic dehydrogenase; L-malate dehydrogenase; NAD-L-malate dehydrogenase; malic acid dehydrogenase; NAD-dependent malic dehydrogenase; NAD-malate dehydrogenase; NAD-malic dehydrogenase; malate (NAD) dehydrogenase; NAD-dependent malate dehydrogenase; NAD-specific malate dehydrogenase; NAD-linked malate dehydrogenase; MDH (ambiguous); L-malate-NAD+ oxidoreductase
Systematic name: (S)-malate:NAD+ oxidoreductase
Comments: There are several forms of malate dehydrogenases that differ by their use of substrate and cofactors. This NAD+-dependent enzyme forms oxaloacetate and unlike EC 1.1.1.38, malate dehydrogenase (oxaloacetate-decarboxylating), is unable to convert it to pyruvate. Also oxidizes some other 2-hydroxydicarboxylic acids. cf. EC 1.1.1.82, malate dehydrogenase (NADP+); EC 1.1.1.299, malate dehydrogenase [NAD(P)+]; and EC 1.1.5.4, malate dehydrogenase (quinone).
