An in vitro Coupled Assay for PEPC with Control of Bicarbonate Concentration
Phosphoenolpyruvate carboxylase (PEPC) catalyzes a critical step in carbon metabolism in plants and bacteria, the irreversible reaction between bicarbonate and phosphoenolpyruvate to produce the C4 compound oxaloacetate.

Cloning and expression of phosphoenolpyruvate carboxykinase from Escherichia coli
In order to better study the structure and function of phosphoenolpyruvate carboxylase, the phosphoenolpyruvate carboxylase gene is cloned and expressed by PCR (polymerase chain reaction), double enzyme digestion and cell transformation. The results show

Modulation of iron responsive gene expression and enzymatic activities in response to changes of the iron nutritional status in _Cucumis sativus_ L. [PDF]
Regulation exerted by the iron status of the plant on the iron deficiency responses was investigated in cucumber roots (_Cucumis sativus_ L.) both at the biochemical and molecular level. Absence of iron induced the expression of the CsFRO1, CsIRT1, CsHA1

Minimizing acetate formation in E. coli fermentations [PDF]
Escherichia coli remains the best established production organisms in industrial biotechnology. However, during aerobic fermentation runs at high growth rates, considerable amounts of acetate are accumulated as by-product.

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)

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.

Light Modulation of Maize Leaf Phosphoenolpyruvate Carboxylase [PDF]
Phosphoenolpyruvate carboxylase (PEPC) was extracted from maize (Zea mays L. cv Golden Cross Bantam T51) leaves harvested in the dark or light and was partially purified by (NH(4))(2)SO(4) fractionation and gel filtration to yield preparations that were 80% homogeneous.

Effect of salicylic acid pretreatment on cadmium toxicity in wheat
Cadmium (100, 400 and 1000 μM CdCl2) treatments resulted in the inhibition of root dry biomass, root elongation and increased Cd accumulation in wheat (Triticum aestivum L.) roots.
