Although the massive accumulation of Suc6P in the cytosol of transgenic leaves was assumed to impair phosphate-recycling into the chloroplast, no obvious signs of phosphate-limitation of photosynthesis became apparent. 3-Phosphoglycerate (3-PGA) levels dropped slightly and the ATP/ADP ratio was not...
The aim of this work was to investigate whether product inhibiton of sucrose-phosphate synthase (SPS) by sucrose-6-phosphate (sucrose6P) plays a significant role in feedback regulation of sucrose synthesis in spinach leaves. The amount of sucrose6P in leaves was very low (0.6-0.7 nmol mg1 ...

enzymatic steps, which makes PPia good candidate for pathway engineering. Abbreviations: UDPG, UDP-glucose; Pi, inorganic phosphate; PPase,E. coliinorganic pyrophosphatase; G1P, glucose-1-phosphate; ADPG, ADP-glucose;F6P, fructose-6-phosphate; FBP, fructose-1,6-bisphosphate; G6P, glucose-6-...
SPS has complex characteristics and is regulated by Pi and G6P, and also via phosphorylation/dephosphorylation (addition and removal of P) by a protein kinase, which uses ATP. SPS is at the interface between sink and source in the plant and may regulate sucrose supply to the sink; probably...

In plants, trehalose 6﹑hosphate (T6P) is a key signaling metabolite that functions as both a signal and negative feedback regulator of sucrose levels. The mode of action by which T6P senses and regulates sucrose is not fully understood. Here, we demonstrate that the sucrolytic activity of...
T6P (6-phosphate), the precursor of , has come out of obscurity over 10 years to be appreciated as an important regulator of plant metabolism and , quite possibly linking the two. This information has been gained from analysis of mutant and transgenic , which show strong, diverse and strat...
Glucose-6-phosphate is oxidized by triphosphopyridine nucleotide (TPN) and glucoses-phosphate dehydrogenase (G6P-DH) to 6-phosphogluconate. Therefore, for each mole of sucrose 2 moles of reduced triphosphopyridine nucleotide (TPNH) are formed. The increase of optical density at 366 or 340 mμ...
AIMS: To examine if sucrose has an analgesic effect on infant colic. METHODS: Nineteen infants with typical infant colic were given 2 ml of 12% sucrose or distilled water when crying, in a double blind double crossover study. The effect was measured by parents' score. RESULTS: Twelve improv...
