When dormant roots of carrot or sugarbeet were transferred from 7 掳C to higher temperature, the concentration of fructose 2,6-bisphosphate in tissue changes within minutes, which response resembles an oscillatory-type function. The mechanism responsible for osciallatory fluctuation of fructose 2,6-...

We identified a point mutation in FBP1 that renders it insensitive to AMP while sparing regulation by fructose-2,6-bisphosphate (F-2,6-P2), and knock-in (KI) of this mutant in mice significantly reduces their response to metformin treatment. We observe this during a metformin tolerance test...
ML349 clinical trial The vascular endothelial function, in terms of flow-mediated dilatation (FMD) of the brachial artery, is commonly evaluated using ultrasound as the gold standard. The measurement of FMD, until now, has faced impediments which have stopped its integration into regular clinical ...
The present review addresses recent advances in research into a family of bifunctional enzymes that are responsible for the twofold task of synthesizing and hydrolyzing fructose-2,6-bisphosphate (Fru-2,6-P2), which in turn regulates the rate of glycolysis in most cells. The structure of the syn...
FBP1 activity can be allosterically or competitively regulated by AMP and fructose-2,6-bisphosphate, respectively.27Thus, a metabolic enzyme that moonlights as a protein phosphatase, such as FBP1, might possess the special capability to integrate the metabolic signals to the network of signal transd...
The biological function of fructose-2,6-bisphosphate 6-phosphatase with an apparent Michaelis constant between 7 and 79 μm fructose 2,6-bisphosphate at Ph 6–7 is therefore suggested to participate in the maintenance of a steady-state level of fructose 2,6-bisphosphate in a concentration range...
Figure 9.5.Fructose 1,6-bisphosphatase represents the entrance valve for the conversion of the CO2assimilates into sucrose. The enzyme is inhibited by the regulatory metabolite fructose 2,6-bisphosphate (Fru2,6BP). The pyrophosphate-dependent fructose 6-phosphate kinase, which synthesizes fructose ...
A key regulator of glycolysis is 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2). By controlling the level of fructose 2,6-bisphosphate (Fru 2,6-P2), PFK-2/FBPase-2 is the central enzyme in controlling the balance between glycolysis and gluconeogenesis [15]. This is...
