Malate to pyruvate reduction or oxidation
WebMalate dehydrogenase ( EC 1.1.1.37) ( MDH) is an enzyme that reversibly catalyzes the oxidation of malate to oxaloacetate using the reduction of NAD + to NADH. This … WebOnce inside the mitochondria, malate can be oxidized to OAA to produce NADH. OAA canʼt pass through the mitochondrial membrane, so it requires transamination to aspartate, …
