Mdh2, is also known as Malate dehydrogenase 2. Mdh2 catalyzes the reversible oxidation of malate to oxaloacetate, utilizing the NAD/NADH cofactor system in the citric acid cycle. In particular, Mdh2 is localized to the mitochondria and may play pivotal roles in the malate-aspartate shuttle that operates in the metabolic coordination between cytosol and mitochondria. It is widely expressed with high expression levels found in adrenal, small intestine, heart and pancreas. Recombinant mouse Mdh2 protein, fused to His-Tag at N-terminal, expressed in E. coli and purified by using conventional chromatography techniques.
