Physiological characteristics and metabolomics of transgenic wheat containing the maize C4 phosphoenolpyruvate carboxylase (PEPC) gene under high temperature stress

Protoplasma, 2016
In this paper, two transgenic wheat lines, PC27 and PC51, containing the maize PEPC gene and its wild-type (WT) were used as experimental material to study the effects of high temperature on their photosynthetic physiological characteristics and metabolome.

Phosphoenolpyruvate carboxylase (PEPC): Mutational analysis of a flexible loop and a putative binding site for an allosteric activator, glucose 6-phosphate (G6P)

, 2001
The crystal structure of E.coli PEPC and Zea mays C4-form PEPC have been resolved recently, and we found an untraceable loop structure from K702 to G708 in E.coli numbering (from K762 to G768 in Zea mays numbering).

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 (

The remarkable diversity of plant PEPC (phosphoenolpyruvate carboxylase): recent insights into the physiological functions and post-translational controls of non-photosynthetic PEPCs

Biochemical Journal, 2011
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.

Studying allelic diversity and stress response of PEPC (Phosphoenolpyruvate carboxylase) in Norway spruce (Picea abies)

Chemosphere, 1998
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.

The appearance of a new molecular species of phosphoenolpyruvate carboxylase (PEPC) and the rapid induction of CAM in Sedum telephium L.

Plant, Cell & Environment, 1990
Abstract. When detached leaves of Sedum telephium are incubated in the absence of water, a rapid switch from C3 photosynthesis to CAM (as indicated by the onset of day‐to‐night fluctuations in titratable acidity. ΔH+) occurs within the first dark period. The C3‐CAM switch in intact plants occurs within 3 5d.

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

, 2012
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
