Expression of Maize Gene Encoding C4-Pyruvate Orthophosphate Dikinase (PPDK) and C4-Phosphoenolpyruvate Carboxylase (PEPC) in Transgenic Arabidopsis

Plant Molecular Biology Reporter, 2012
To improve the efficiency of CO2 fixation in C3 photosynthesis, C4-cycle genes were overexpressed in Arabidopsis plants. In this study, a full-length cDNA for pyruvate orthophosphate dikinase (PPDK) with 971 amino acids was isolated from Zea mays using LA-PCR.

Recombinant thermoactive phosphoenolpyruvate carboxylase (PEPC) from Thermosynechococcus elongatus and its coupling with mesophilic/thermophilic bacterial carbonic anhydrases (CAs) for the conversion of CO2 to oxaloacetate

Bioorganic & Medicinal Chemistry, 2016
With the continuous increase of atmospheric CO2 in the last decades, efficient methods for carbon capture, sequestration, and utilization are urgently required. The possibility of converting CO2 into useful chemicals could be a good strategy to both decreasing the CO2 concentration and for achieving an efficient exploitation of this cheap carbon source.

Characterization, Evolutionary Insights, and Stress-Responsive Expression of the Phosphoenolpyruvate Carboxylase (PEPC) Gene Family in Salix Matsudana

Plant Innovation Journal
Phosphoenolpyruvate carboxylase (PEPC) is a vital enzyme in plant carbon metabolism, catalyzing the conversion of phosphoenolpyruvate (PEP) to oxaloacetate (OAA), a key intermediate in numerous biosynthetic pathways. PEPC family members are usually classified into PTPC and BTPC subfamilies, and PTPC subfamily is characterized by a conserved N-terminal ...

Tree stem phosphoenolpyruvate carboxylase (PEPC): lack of biochemical and localization evidence for a C₄‐like photosynthesis system

New Phytologist, 2007
Here, the kinetic properties and immunolocalization of phosphoenolpyruvate carboxylase (PEPC) and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) in young stems of Fagus sylvatica were investigated. The aim of the study was to test the hypothesis that there is a C4-like photosynthesis system in the stems of this C3 tree species. The activity,

Modulation of phosphoenolpyruvate carboxylase in vivo by Ca2+ in Amaranthus hypochondriacus, a NAD-ME type C4 plant: Possible involvement of Ca2+ in up-regulation of PEPC-protein kinase in vivo

Journal of Plant Physiology, 2005
The properties of phosphoenolpyruvate carboxylase (PEPC) were studied, with respect to calcium (Ca2+), in leaves of Amaranthus hypochondriacus, a C4 plant. Experiments were conducted in vitro (by adding Ca2+ during enzyme assay) or in vivo (by feeding Ca2+ to intact leaves through petiole). Inclusion of 10 microM Ca2+ during assay marginally increased (

Exogenous ATP enhance signal response of suspension cells of transgenic rice (Oryza sativa L.) expressing maize C 4 -pepc encoded phosphoenolpyruvate carboxylase under PEG treatment

Plant Growth Regulation, 2016
The aim of this study was to analyze the biochemical and molecular responses of suspension cells of transgenic rice (Oryza sativa L.) over-expressing the maize C 4 -pepc gene encodes phosphoenolpyruvate carboxylase (PEPC) (PC line) to drought stress by exogenous ATP ...

Regulation of the supply of oxaloacetate for mitochondrial metabolism via phospho enol pyruvate carboxylase in barley leaf protoplasts II. Effects of metabolites on PEPC activity at different activation states of the protein

Biochimica et Biophysica Acta (BBA) - General Subjects, 1996
The regulation of the supply of oxaloacetate (OAA) for mitochondrial metabolism via phosphoenolpyruvate carboxylase (PEPC) by metabolites is studied in barley (Hordeum vulgare L.) leaf protoplasts in light or darkness as well as under photorespiratory or non-photorespiratory conditions.

Régulation du métabolisme carboné sous ozone : rôles de la PhosphoEnolPyruvate carboxylase (PEPC) et des enzymes NADP-dépendantes

L'ozone (O3), polluant atmosphérique et gaz à effet de serre, est responsable des pertes de production pour plusieurs espèces végétales. Actuellement, les seuils de risques ne prennent pas en considération la capacité de détoxication intrinsèque des cellules, qui dépend en partie de la régénération du NADPH. Dans cette dernière perspective, l'étude des
