Phosphoenolpyruvate Carboxylase of Salmonella
Abstract Phosphoenolpyruvate carboxylase from Salmonella typhimurium has been purified to homogeneity. The enzyme shows a concentration-dependent aggregation in ultracentrifugal experiments. Depending upon the age of enzyme preparations the s20w values range between 11.8 to 16.9 at about 2 mg per ml and between 41.6 to 53 at concentrations higher than ...

Characterization and Expression Analysis of Genes Encoding Phosphoenolpyruvate Carboxylase and Phosphoenolpyruvate Carboxylase Kinase of Lotus japonicus, a Model Legume [PDF]
Phosphoenolpyruvate carboxylases (PEPCs), one form of which in each legume species plays a central role in the carbon metabolism in symbiotic root nodules, are activated through phosphorylation of a conserved residue by a specific protein kinase (PEPC-PK)

Oligomerization and the Sensitivity of Phosphoenolpyruvate Carboxylase to Inactivation by Proteinases [PDF]
Phosphenolpyruvate (PEP) carboxylase from leaves of Crassula argentea displays varying levels of sensitivity to inactivation by various proteolytic enzymes. In general, the native enzyme is sensitive to proteinases known to attack at the carbonyl end of lysine or arginine (trypsin, papain, or bromelain).

Conservation and Divergence of Phosphoenolpyruvate Carboxylase Gene Family in Cotton
Phosphoenolpyruvate carboxylase (PEPC) is an important enzyme in plants, which regulates carbon flow through the TCA cycle and controls protein and oil biosynthesis. Although it is important, there is little research on PEPC in cotton, the most important

Wild-type C. glutamicum ATCC 13032 is known to possess two enzymes with anaplerotic (C4-directed) carboxylation activity, namely phosphoenolpyruvate carboxylase (PEPCx) and pyruvate carboxylase (PCx). On the other hand, C3-directed decarboxylation can be

The molecular mechanism of propionate-regulating gluconeogenesis in bovine hepatocytes [PDF]
Objective Cows that are nursing get around 80% of their glucose from liver gluconeogenesis. Propionate, a significant precursor of liver gluconeogenesis, can regulate the key genes involved in hepatic gluconeogenesis expression, but its precise effects ...

Phosphoenolpyruvate 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 CO2 and is abundant in both C4 and crassulacean ...

Regulation at the Phosphoenolpyruvate Branchpoint in Azotobacter vinelandii : Phosphoenolpyruvate Carboxylase [PDF]
Phosphoenolpyruvate carboxylase (EC 4.1.1.31) from Azotobacter vinelandii , like the corresponding enzyme from other organisms, is activated by acetyl coenzyme A and inhibited by l -aspartate. Both modifiers affect primarily the affinity of the enzyme for phosphoenolpyruvate.
