- (S)-malat + hinon oksaloacetat + redukovani hinon
Ovaj enzim je flavoprotein (FAD). Vitamin K i nekoliko drugih hinona mogu da deluju kao akceptori. On se razlikuje od EC 1.1.1.37 (malat dehidrogenaze (NAD+)), EC 1.1.1.82 (malat dehidrogenaza (NADP+)) i EC 1.1.1.299 (malat dehidrogenaza (NAD(P)+)).
