Binding Sites of Bicarbonate in Phosphoenolpyruvate Carboxylase

Journal of Chemical Information and Modeling
Phosphoenolpyruvate carboxylase (PEPC) is used in plant metabolism for fruit maturation or seed development as well as in the C4 and crassulacean acid metabolism (CAM) mechanisms in photosynthesis, where it is used for the capture of hydrated CO2 (bicarbonate). To find the yet unknown binding site of bicarbonate in this enzyme, we have first identified

Regulation of soybean nodule phosphoenolpyruvate carboxylase in vivo

Physiologia Plantarum, 1996
The sensitivity of soybean (Glycine max L. Merr, cv. PS47) nodule phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) to inhibition by L‐malate in vitro increased when well‐nodulated plants were subjected to decapitation (shoot removal). There was no effect of decapitation on the apparent Km of the enzyme for its substrate PEP but the I50 (L‐malate ...

Comparative studies of coupled assays for phosphoenolpyruvate carboxylase

Physiologia Plantarum, 1994
Phosphoenolpyruvate carboxylase (PEPC) from higher plants is usually assayed by using malate dehydrogenase (MDH) as a coupling enzyme. To avoid erroneous readings caused by metal ions, which convert oxaloacetate (OAA) to pyruvate, lactic dehydrogenase can be included. Reporting the total NADH used by both coupling enzymes gives the total OAA production.

Control of the phosphorylation of phosphoenolpyruvate carboxylase in higher plants

Archives of Biochemistry and Biophysics, 2003
Phosphoenolpyruvate (PEP) carboxylase is regulated by reversible phosphorylation in higher plants. Recently several genes encoding PEP carboxylase kinase have been cloned. The purpose of this article is to assess the contribution that information on the structure and expression of these genes is making to our understanding of the posttranslational ...

Partial purification and characteristics of potato phosphoenolpyruvate carboxylase

Archives of Biochemistry and Biophysics, 1968
Abstract Phosphoenolpyruvate (PEP) carboxylase was purified over 200-fold from potatoes ( Solanum tuberosum ). An apparent molecular weight of 265,000 was obtained by sucrose gradient centrifugation. It does not appear to dissociate or aggregate in the presence of substrates, within the pH range of 6–8, or in an ionic strength (0.5) that produces ...
