Phosphoenolpyruvate carboxylase, Microorganism

Phosphoenolpyruvate carboxylase, Microorganism (PEPC) is a carbon dioxide fixing enzyme that in an irreversible manner and in the presence of Mg2+, converts phosphoenolpyruvate and bicarbonate into oxaloacetate and inorganic phosphorus. Phosphoenolpyruvate carboxylase catalyses the primary assimilation of CO (2) in Crassulacean acid metabolism plants. Phosphoenolpyruvate carboxylase plays a major role in setting the day-night pattern of metabolism in plants[1][2].
