Phosphoenolpyruvate carboxylase (also known as PEP carboxylase, PEPCase, or PEPC; EC 4.1.1.31, PDB ID: 3ZGE) is an enzyme in the family of carboxy-lyases found in plants and some bacteria that catalyzes the addition of bicarbonate (HCO3 ) to phosphoenolpyruvate (PEP) to form the four-carbon compound … See more The PEP carboxylase enzyme is present in plants and some types of bacteria, but not in fungi or animals (including humans). The genes vary between organisms, but are strictly conserved around the active and allosteric sites discussed … See more The three most important roles that PEP carboxylase plays in plants and bacteria metabolism are in the C4 cycle, the CAM cycle, … See more The mechanism of PEP carboxylase has been well studied. The enzymatic mechanism of forming oxaloacetate is very exothermic and thereby irreversible; the biological Gibbs free energy change (△G°’) is -30kJmol . The substrates and cofactor bind in the following … See more PEP carboxylase is mainly subject to two levels of regulation: phosphorylation and allostery. Figure 3 shows a schematic of the regulatory mechanism. Phosphorylation by … See more WebPhosphoenolpyruvate carboxylase (PEP carboxylase), the key enzyme of C 4 metabolism, is highly regulated. In a darkened leaf, this enzyme has low activity. In this state, the affinity …
