Aplicação
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 .
Ações bioquímicas/fisiológicas
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 .
Definição da unidade

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)

Phosphoenolpyruvate carboxylase is an ubiquitous cytosolic enzyme that catalyzes the ß-carboxylation of phosphoenolpyruvate (PEP) and is encoded by multigene family in plants. It plays an important role in carbon economy of plants by assimilating CO2 into organic acids for subsequent

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
