Fructose 2,6-bisphosphate in human platelets: its possible role in the control of basal and thrombin-stimulated glycolysis. 1986

M Farnararo, and P Bruni, and V Vasta

Human platelets contain fructose 2,6-bisphosphate, 6-phosphofructo-l-kinase (ATP: D-Fructose-6-phosphate-1-phosphotransferase, E.C.2.7. 1.11), the rate-limiting enzyme in platelet glycolysis appear to be significantly activated by physiological concentration of the compound, suggesting for fructose 2,6-bisphosphate a key regulatory role in the control of the glycolytic flux. Incubation of human platelets with thrombin results in a parallel and rapid increase of fructose-2,6-bisphosphate levels and glycolytic flux, suggesting that the compound may also be involved in the enhancement of glycolysis elicited by the stimulating agent.

D006019 Glycolysis A metabolic process that converts GLUCOSE into two molecules of PYRUVIC ACID through a series of enzymatic reactions. Energy generated by this process is conserved in two molecules of ATP. Glycolysis is the universal catabolic pathway for glucose, free glucose, or glucose derived from complex CARBOHYDRATES, such as GLYCOGEN and STARCH.
