Application

Phosphoenolpyruvate carboxylase (PEPC) is an enzyme useful for enzymatic determination of carbon dioxide when coupled with malate dehydrogenase in clinical analysis. PEPC is also used to study carbon assimilation, post-translational regulation and allosteric regulation in various plants .

Biochem/physiol Actions

Phosphoenolpyruvate carboxylase (PEPC) catalyzes the addition of bicarbonate to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate and inorganic phosphate . In CAM and C4 plants, PEPC catalyzes the photosynthetic assimilation of CO2 into an organic acid. PEPC is activated by glucose-6-phosphate and is inhibited by malate and aspartate. PEPC comprises about 0.5-2% of the soluble protein in alfalfa and soybean nodules .

Unit Definition

One unit causes the oxidation of one micromole of NADH per minute at pH 8.0 at 30°C.

Physical form

White amorphous lyophilized powder containing BSA and sugar alchohols as stabilizers.

Phosphoenolpyruvate carboxylase (PEPC, EC 4.1.1.31) is believed to play a significant role in supporting nitrogen fixation via anaplerotic CO2 fixation for recycling carbon in nodules. Using the antisense technique, we decreased the expression levels of the nodule-enhanced PEPC gene (Ljpepc1)

The C4-photosynthetic carbon cycle is an elaborated addition to the classical C3-photosynthetic pathway, which improves solar conversion efficiency. The key enzyme in this pathway, phosphoenolpyruvate carboxylase, has evolved from an ancestral non-photosynthetic C3 phosphoenolpyruvate carboxylase. During evolution, C4 phosphoenolpyruvate carboxylase
