One unit will cause the oxidation of 1,0 µmole of NADH per minute at pH 7,4 and 25 °C.

Malate dehydrogenase is an enzyme that reversibly catalyses the oxidation of malate to oxaloacetate using the reduction of NAD+ to NADH.

Malate dehydrogenase can be used for enzymatic determination of L-malate and gluamate oxaloacetate transaminase (GOT).
