WebPhosphoenolpyruvate carboxylase (PEPC) is a ubiquitous cytosolic enzyme, which is crucial for plant carbon metabolism. PEPC participates in photosynthesis by catalyzing the initial fixation of atmospheric CO 2 and is abundant in both C 4 and crassulacean acid metabolism leaves. PEPC is differentially expressed at different stages of plant ... WebJan 14, 2015 · Phospho enol pyruvate carboxylase ( PEPC) is a crucial enzyme that catalyzes an irreversible primary metabolic reaction in plants. Previous studies have used transgenic plants expressing ectopic PEPC forms with diminished feedback inhibition to examine the role of PEPC in carbon and nitrogen metabolism.
