Inhibition of the enzyme phosphoenolpyruvate-carboxylase (PEPC) by different pollutants

Talanta, 1997
The inhibitory effect of different pollutants on the enzyme phosphoenolpyruvate-carboxylase was investigated. For this enzyme, different procedures are described for determining the activity of the enzyme. Determination of the presence of the enzymatically-formed oxaloacetate was found to be more suitable for this purpose because of the higher ...

Phosphorylation of phosphoenolpyruvate carboxykinase (PEPCK) and phosphoenolpyruvate carboxylase (PEPC) in the flesh of fruits

Plant Physiology and Biochemistry, 2016
This study determined whether phosphoenolpyruvate carboxykinase (PEPCK) and phosphoenolpyruvate carboxylase (PEPC) are phosphorylated in the flesh of a range of fruits. This was done by incubating fruit flesh with 32P[P] (where 32P[P] = 32PO43-), then PEPCK and PEPC were immunoprecipitated from extracts using specific antisera. The incorporation of 32P[

Phosphoenolpyruvate carboxylase (PEPC) and PEPC-kinase (PEPC-k) isoenzymes in Arabidopsis thaliana: role in control and abiotic stress conditions

Planta, 2016
Arabidopsis ppc3 mutant has a growth-arrest phenotype and is affected in phosphate- and salt-stress responses, showing that this protein is crucial under control or stress conditions. Phosphoenolpyruvate carboxylase (PEPC) and its dedicated kinase (PEPC-k) are ubiquitous plant proteins implicated in many physiological processes.

The remarkable diversity of plant PEPC (phosphoenolpyruvate carboxylase): recent insights into the physiological functions and post-translational controls of non-photosynthetic PEPCs

Biochemical Journal, 2011
PEPC [PEP (phosphoenolpyruvate) carboxylase] is a tightly controlled enzyme located at the core of plant C-metabolism that catalyses the irreversible β-carboxylation of PEP to form oxaloacetate and Pi. The critical role of PEPC in assimilating atmospheric CO2 during C4 and Crassulacean acid metabolism photosynthesis has been studied extensively.

Drought tolerance and proteomics studies of transgenic wheat containing the maize C4 phosphoenolpyruvate carboxylase (PEPC) gene

Protoplasma, 2015
Enhancing drought tolerance of crops has been a great challenge in crop improvement. Here, we report the maize phosphoenolpyruvate carboxylase (PEPC) gene was able to confer drought tolerance and increase grain yield in transgenic wheat (Triticum aestivum L.) plants.

Influence of allosteric effectors on the kinetics and equilibrium binding of phosphoenolpyruvate (PEP) to phosphoenolpyruvate carboxylase (PEPC) from Zea mays

Biophysical Chemistry, 2001
Phosphoenolpyruvate carboxylase (PEPC) the carbon dioxide processing enzyme of C(4) plants, shows the features of an allosteric enzyme. Allosteric activators such as D-glucose-6-phosphate and glycine increase the affinity of PEPC for its substrate PEP at pH 8.0 and pH 7.0.
