WebThe purity of the preparations was also evident from the exclusive localization of phosphopyruvate carboxylase (EC 4.1.1.31) and NADP-dependent malate dehydrogenase (EC 1.1.1) in mesophyll cells and ribulose 1,5-diphosphate carboxylase (EC 4.1.1.39), phosphoribulokinase (EC 2.7.1.19), and "malic enzyme" (EC 1.1.1.40) in bundle sheath cells. 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 … See more PEP carboxylase is mainly subject to two levels of regulation: phosphorylation and allostery. Figure 3 shows a schematic of the regulatory … See more
