“…Remarkably, organisms that do not depend on the degradation of organic compounds for energy, such as phototrophs, may forfeit glycolytic ATP production altogether. These organisms substantially increase the chemical motive force of the pathway reactions by bypassing the substrate-level phosphorylation step and using glycolysis solely for the production of carbon skeletons 90,91 .…”

“…In Arabidopsis, for example, it has been shown that GAPDH proteolysis is modulated by binding to regulatory 14-3-3 proteins, through protein phosphorylation [33]. In plants, a cytosolic nonphosphorylating GAPDH is occurring in addition to glycolitic GAPDH; this phosphorylated enzyme is involved in the generation of NADPH and is modulated by oxidative stress [34]. Proteins belonging to the photosynthetic apparatus, namely two components of the photosystem II oxygenevolving complex (spots 4 and 5), a component of the cytochrome b 6 -f complex (spot 9) and an extrinsic protein associated to the PS II complex (spot 7), also showed lower levels of their phosphorylated species.…”

“…Metabolic flux has to be regulated between generating hexose-Ps via gluconeogenesis and glycolytic "downstream" products, such as 3-PGA, PEP, and pyruvic acid. In higher plants, the redox transfer by a TP/3-PGA shuttle via nonphosphorylating glyceraldehyde-3-P dehydrogenase and 3-PGA kinase is proposed to be marginal and glyceraldehyde-3-P dehydrogenase expression is mainly induced under stress conditions, such as anaerobiosis and heat shock or Suc feeding (Yang et al, 1993;Bustos et al, 2008;Holtgrefe et al, 2008). On the other hand, glycolysis In photosynthetically active cells, TP is exported via the GsTPT from rhodoplasts to sustain soluble and insoluble carbohydrate synthesis (floridoside and floridean starch) in the cytosol.…”
