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[

Inhibition of the enzyme phosphoenolpyruvate-carboxylase (PEPC) by different pollutants
Talanta, 1997The 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 ...

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.

Using particle bombardment transformation, we introduced maize pepc cDNA encoding phosphoenolpyruvate carboxylase (PEPC) and ppdk cDNA encoding pyruvate orthophosphate dikinase (PPDK) into the C3 crop wheat to generate transgenic wheat lines carrying cDNA of pepc (PC lines), ppdk (PK lines) or both (PKC lines).

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.

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.

Abstract A novel experimental approach in ecological genetics for analysing allelic diversity at an isoenzyme-gene-system is presented. This approach is based on the question how individual genetic diversity is implemented in adaptive processes towards stress.

Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) has important functions in C4 photosynthesis and biosynthesis of intermediate metabolites. In this study, the drought resistance of C4‐PEPC‐expressing transgenic rice (Oryza sativa, line PC) plants was assessed using simulated drought conditions [i.e. polyethylene glycol (PEG)‐6000 treatment]. The dry

The thermodenaturation of phosphoenolpyruvate carboxylase (PEPC) from an extremely thermophilic bacterium Rhodothermus obamensis, capable of growth at temperature up to 85°C, was probed at different denaturation temperatures by UV-visible absorption, fluorescence emission and 1-anilinonaphthalene-8-sulfonate (ANS) binding and renaturation was assessed ...
