Descrizione generale

Malic dehydrogenase is a mitochondrial isozyme and an important catalyst in the tricarboxylic acid cycle.
Mitochondrial Isozyme

Applicazioni

Malic dehydrogenase has been used in a study to assess the comparative molluscicidal action of Ginko biloba extract on snail hosts. It has also been used in a study to investigate the effect of early feed restriction on metabolic programming and compensatory growth in broiler chickens.

Azioni biochim/fisiol

Eukaryotic cells contain two different isozymes of malate dehydrogenase: mitochondrial (m-MDH) and soluble or cytoplasmic (s-MDH). This product consists of the mitochondrial form.
The enzyme catalyzes the following reaction:Oxaloacetate + β-NADH → L-Malate + β-NAD
Malic Dehydrogenase can be reversibly inactivated by treatment with pyridoxal 5′-phosphate at 25 °C.

Definizione di unità

One unit will convert 1.0 μmole of oxalacetate and β-NADH to L-malate and β-NAD per min at pH 7.5 at 25 °C.

Stato fisico

Solution in 50% glycerol containing 0.05 M potassium phosphate buffer, pH 7.5

Phosphoenolpyruvate carboxylase (PEPC) catalyzes a critical step in carbon metabolism in plants and bacteria, the irreversible reaction between bicarbonate and phosphoenolpyruvate to produce the C4 compound oxaloacetate. This enzyme is particularly important in the context of C4 photosynthesis, where it
