Description générale

Malic dehydrogenase (MDH) exists as two isoforms within eukaryotic cells, one that is expressed in the mitochondria and functions in the TCA cycle and one in the cytoplasm that converts malate from the mitochondria back into oxaloacetate.

Application

Malic dehydrogenase has been used in a study to assess the dietary manganese requirement of juvenile yellow catfish (Pelteobagrus fulvidraco) and effects on whole body mineral composition and hepatic intermediary metabolism. It has also been used in a study to investigate the establishment and biological characterization of a fibroblast cell line from the Langshan chicken.

Actions biochimiques/physiologiques

Expression of malic dehydrogenase in chicken liver is induced upon feeding and decreases in response to starvation.

Définition de l'unité

One unit will convert 1.0 μmole of L-malate and NADP to pyruvate, CO2, and NADPH per min at pH 7.4 at 25 °C.

Forme physique

Suspension in 2.9 M (NH4)2SO4 solution containing 10 mM potassium phosphate, 0.5 mM 2-mercaptoethanol, 10 mM manganese chloride, and 3 mM Na4EDTA, pH 6.0

NADP-malic enzyme (NADP-ME, EC 1.1.1.40) was purified to near-homogeneity from leaves of the C4 dicot Flaveria bidentis and shown to possess intrinsic NAD-dependent malic enzyme activity. The NAD-dependent activity is optimal at pH 7.5 and in the presence of Mn2+.
