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[

Evolution of C4 phosphoenolpyruvate carboxylase
Archives of Biochemistry and Biophysics, 2003C4 plants are known to be of polyphyletic origin and to have evolved independently several times during the evolution of angiosperms. This implies that the C4 isoform of phosphoenolpyruvate carboxylase (PEPC) originated from a nonphotosynthetic PEPC gene that was already present in the C3 ancestral species.

Nodule phosphoenolpyruvate carboxylase: a review
Physiologia Plantarum, 1988Recent data concerning the fixation of CO2 and the functioning of phosphoenolpyruvate (PEP) carboxylase (EC 4.1.1.31) in legume, nodules are reviewed. The activites of N2 fixation (acctylene reduction) and PEP carboxylase are correlated Activities of PEP carboxylase are always higher in nodules than in roots.

Effect of LiCl on phosphoenolpyruvate carboxylase kinase and the phosphorylation of phosphoenolpyruvate carboxylase in leaf disks and leaves of Sorghum vulgare [PDF]
Planta, 2006 In the present work, the effect of LiCl on phosphoenolpyruvate carboxylase kinase (PEPCase-k), C4 phosphoenolpyruvate carboxylase (PEPCase: EC 4.1.1.31) and its phosphorylation process has been investigated in illuminated leaf disks and leaves of the C4 plant Sorghum vulgare.

Phosphoenolpyruvate carboxylase: structure, regulation and evolution
Plant Science, 1994Abstract Plant phosphoenolpyruvate carboxylase (EC 4.1.1.31; PEPC) is encoded by a small multigene family in which the expression of each member is controlled individually by exogenous (light, environmental) and/or endogenous (hormonal and developmental) stimuli.

The unique phosphoenolpyruvate carboxylase kinase
Plant Physiology and Biochemistry, 2003Abstract This paper deals with the contribution of P. Gadal’s group to the study of the phosphoenolpyruvate carboxylase protein kinase. It traces the important steps from the discovery up to the present time leading to characterize a new protein kinase which is specific for plants and displays original properties.

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 ...

Phosphoenolpyruvate carboxylase assay on polyacrylamide gels
Experientia, 1979A simple technique to identify, PEP carboxylase on polyacrylamide gels is described. This method involves in the formation of white ring of calcium phosphate precipitate on the reaction site, revealing the presence of enzyme protein.

A procedure for the electrophoretic analysis of phosphoenolpyruvate carboxylase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1973Abstract Phosphoenolpyruvate carboxylase from Euglena gracilis was analyzed electrophoretically using an agar suspension of the reaction mixture to detect the enzyme bands. Since the stain is specific for oxaloacetate produced by the enzyme, it should be possible to extend this technique to other enzymes concerned with oxaloacetate metabolism.

Hydrolysis of phosphoenolpyruvate catalyzed by phosphoenolpyruvate carboxylase from Zea mays
Biochemistry, 1992In addition to the normal carboxylation reaction, phosphoenolpyruvate carboxylase from Zea mays catalyzes a HCO3(-)-dependent hydrolysis of phosphoenolpyruvate to pyruvate and Pi. Two independent methods were used to establish this reaction. First, the formation of pyruvate was coupled to lactate dehydrogenase in assay solutions containing high ...
