WebIn contrast, fructose-1,6-bisphosphate (F1,6BP) closed ScMUC and thus inhibited the rate of oxygen consumption. When added together, F1,6BP reverted the mild G6P-induced effects. F1,6BP is proposed to be an important modulator of ScMUC, whose closure contributes to the "Crabtree effect". WebThe EPSC AMPA was typically fast (~20 ms) with an amplitude of ~200 pA (Figure 4A). Addition of F1,6BP (5 mM) ... A reduction in the strength of this type of inhibition by F1,6BP might therefore contribute to the reduction of epileptiform activity. Whether F1,6BP exerts additional effects on intracellular metabolic pathways in our model remains ...
WebFructose-1,6-Bisphosphatase (FBPase) Deficiency. FBPase is a key gluconeogenic enzyme, catalyzing the hydrolysis of fructose-1,6-bisphosphate to fructose-6-phosphate and inorganic phosphate. Two different paralogs exist in humans; FBP1 is found in the liver, and FBP2 is found in muscle. FBP1 is encoded by the gene FBP1, a 31-kbp 7-exon gene ...
