the relative mRNA level of glucokinase (gck), phosphofructokinase (pfk), and pyruvate kinase L/R (pk) was analyzed by quantitative PCR. The transcriptional levels ofgck,pfk
phosphoenolpyruvate carboxylase kinase can be overridden by changes in metabolite levels. The primary effect of the circadian oscillator in this system may be at the level of thetonoplast, and changes in kinase expression may be secondary to circadian changes in the concentration of a metabolite, ...

The enzyme phosphoenolpyruvate (PEP) carboxylase (PEPC; EC 4.1.1.31) catalyzes the irreversible β-carboxylation of PEP in the presence of bicarbonate (HCO3−) and Mg2+or Mn2+to yield oxaloacetate (OAA) and inorganic phosphate (Pi)1. It is widely distributed in archaea, bacteria, cyanobacteria...

kinase-like and the OAA decarboxylase reactions represent the phosphoryl transfer and decarboxylation steps of the main reaction, respectively, linked through the formation of enolpyruvate as a reaction intermediate [5–7]. The absence of secondary activities in some PEP carboxyki- nases might be du...
transgenic plants, oryza sativa, phosphoenolpyruvate carboxylase, tracer techniques, c4 plantsIn a previous study, we isolated a full length cDNA and the corresponding gene encoding a C4-like pyruvate, orthophosphate dikinase (PPDK) from rice, a C3 gramineous plant (1). The deduced amino acid ...
The hormesis response of transient starvation stress promotes calcium calmodulin kinase II and ether-a-go-go-like K+ channel functions. These molecules mitigate the increases of age-related muscle excitability (Guo et al., 2012, LeBoeuf et al., 2011). In contrast to starved animals, if well...
