一般說明
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.
應用
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.
生化／生理作用
Expression of malic dehydrogenase in chicken liver is induced upon feeding and decreases in response to starvation.
單位定義
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.

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+.
