ENZYME entry: EC

Accepted Name
L-2-hydroxycarboxylate dehydrogenase [NAD(P)(+)].
Alternative Name(s)
lactate/malate dehydrogenase.
Reaction catalysed
  • a (2S)-2-hydroxycarboxylate + NAD(+) <=> a 2-oxocarboxylate + H(+) + NADH
  • a (2S)-2-hydroxycarboxylate + NADP(+) <=> a 2-oxocarboxylate + H(+) + NADPH
  • The enzyme from the archaeon Methanocaldococcus jannaschii catalyzes the reversible oxidation of (2R)-3-sulfolactate and (S)-malate to 3-sulfopyruvate and oxaloacetate, respectively (note that (2R)-3- sulfolactate has the same stereochemical configuration as (2S)-2- hydroxycarboxylates).
  • The enzyme can use both NADH and NADPH, although activity is higher with NADPH.
  • The oxidation of (2R)-3-sulfolactate was observed only in the presence of NADP(+).
  • The same organism also possesses an NAD(+)-specific enzyme with similar activity, cf. EC
