PEPC of sugarcane regulated glutathione S-transferase and altered carbon–nitrogen metabolism under different N source concentrations in Oryza sativa [PDF]
BMC Plant Biology, 2021 Background Phosphoenolpyruvate carboxylase (PEPC) plays an important role in the primary metabolism of higher plants. Several studies have revealed the critical importance of PEPC in the interaction of carbon and nitrogen metabolism.

Kranz and single-cell forms of C4plants in the subfamily Suaedoideae show kinetic C4convergence for PEPC and Rubisco with divergent amino acid substitutions [PDF]
Journal of Experimental Botany, 2015 Highlight Enzyme kinetic measurements and positive selection analysis show that C4 species in Suaedoideae have PEPC and Rubisco kinetics similar to other C4 species despite different amino acid convergence.

Contribution of carbon fixed by Rubisco and PEPC to phloem export in the Crassulacean acid metabolism plant Kalanchoë daigremontiana [PDF]
Journal of Experimental Botany, 2010 Crassulacean acid metabolism (CAM) plants exhibit a complex interplay between CO2 fixation by phosphoenolpyruvate carboxylase (PEPC) and ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco), and carbon demand for CAM maintenance and growth.

Bacterial-type Phosphoenolpyruvate Carboxylase (PEPC) Functions as a Catalytic and Regulatory Subunit of the Novel Class-2 PEPC Complex of Vascular Plants [PDF]
Journal of Biological Chemistry, 2009 Phosphoenolpyruvate carboxylase (PEPC) is a tightly regulated anaplerotic enzyme situated at a major branch point of the plant C metabolism. Two distinct oligomeric classes of PEPC occur in the triglyceride-rich endosperm of developing castor oil seeds ...

PepC: proteomics software for identifying differentially expressed proteins based on spectral counting [PDF]
Bioinform., 2010 UNLABELLED Identifying biologically significant changes in protein abundance between two conditions is a key issue when analyzing proteomic data. One widely used approach centers on spectral counting, a label-free method that sums all the tandem mass ...

Physiological and photosynthetic characteristics of indica Hang2 expressing the sugarcane PEPC gene [PDF]
Molecular Biology Reports, 2014 Phosphoenolpyruvate carboxylase (PEPC) is known to play a key role in the initial fixation of CO2 in C4 photosynthesis. The PEPC gene from sugarcane (a C4 plant) was introduced into indica rice (Hang2), a process mediated by Agrobacterium tumefaciens ...

Light-regulated and cell-specific methylation of the maize PEPC promoter [PDF]
Journal of Experimental Botany, 2011 The molecular mechanisms governing PEPC expression in maize remain to be fully defined. Differential methylation of a region in the PEPC promoter has been shown to correlate with transcript accumulation, however, to date, investigations into the role of ...
