- W2138728883 abstract "Vanadate (0.1–1 mM) was supplied to leaves of barley (Hordeum vulgare var. Roland) via the transpiration stream. It led to a selective inhibition of the rate of photosynthesis at high light without altering the initial slope of the light response curve, produced markedly biphasic photosynthesis induction kinetics, and selectively decreased sucrose synthesis compared to starch synthesis. There was a 3-fold increase of the steady state level of the signal metabolite fructose-2,6-bisphosphate in near saturating light. Fructose-2,6-bisphosphate is a potent inhibitor of cytosolic fruc-tose-l,6-bisphosphatase and, in agreement, the fructose-1,6-bisphosphatc level doubled. The increase of fructose-2,6-bisphosphate could not be accounted for by the known regulation of fructose-6-phosphate,2-kinase and fructose 2,6-bisphosphatase by 3-phosphoglycerate and fiuctose-6-phosphate, because these metabolites remained constant or even changed in the opposite direction to that required to generate an increase of fructose-2,6-bisphosphate. Instead, vanadate strongly inhibited the hydrolysis of fructose-2,6-bisphosphate in extracts, producing a half maximal inhibition at 2 nM and 50 iM in assays designed to preferentially measure the high-and low-affinity forms of fructose-2,6-bisphosphatase, respectively. Vanadale had no effect on fructosc-6-phosphate,2-kinase activity at these concentrations. Vanadate also led to a deactivation of sucrose phosphate synthase. The results are discussed in relation to the role of fructose-2,6-bisphosphate in regulating sucrose synthesis, and its interaction with the ‘coarse’ control of sucrose phosphate synthase." @default.
