C4 Phosphoenolpyruvate Carboxylase: Evolution and transcriptional regulation

open access: yesGenetics and Molecular Biology, 2023
Photosynthetic phosphoenolpyruvate carboxylase (PEPC) catalyses the irreversible carboxylation of phosphoenolpyruvate (PEP), producing oxaloacetate (OAA).

Phosphoenolpyruvate Carboxylase of Salmonella

open access: hybridJournal of Biological Chemistry, 1969
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]

open access: yesMolecular Plant-Microbe Interactions, 2003
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]

open access: bronzePlant Physiology, 1987
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

open access: yesPlants, 2022
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

Comprehensive Analysis of C. glutamicum Anaplerotic Deletion Mutants Under Defined d-Glucose Conditions

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
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

Production of succinate by engineered strains of Synechocystis PCC 6803 overexpressing phosphoenolpyruvate carboxylase and a glyoxylate shunt

open access: yesMicrobial Cell Factories, 2021
Background Cyanobacteria are promising hosts for the production of various industrially important compounds such as succinate. This study focuses on introduction of the glyoxylate shunt, which is naturally present in only a few cyanobacteria, into ...

The molecular mechanism of propionate-regulating gluconeogenesis in bovine hepatocytes [PDF]

open access: yesAnimal Bioscience, 2023
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 ...

Differential Expression, Tissue-Specific Distribution, and Posttranslational Controls of Phosphoenolpyruvate Carboxylase

open access: yesPlants, 2021
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]

open access: yesJournal of Bacteriology, 1971
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.
