SYSTEMATIC NAME
IUBMB Comments
(S)-malate:NAD(P)+ oxidoreductase
This enzyme, which was characterized from the methanogenic archaeon Methanobacterium thermoautotrophicum, catalyses only the reduction of oxaloacetate, and can use NAD+ and NADP+ with similar specific activity [1]. Different from EC 1.1.1.37 (malate dehydrogenase (NAD+)), EC 1.1.1.82 (malate dehydrogenase (NADP+)) and EC 1.1.5.4 (malate dehydrogenase (quinone)).
