Application

Ribulose-1,5-bisphosphate (RuBP) is a component of the Calvin cycle that is metabolized into glycerate 3-phosphate (G3P) by the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO). RuBP is used to identify, differentiate and characterize ribulose bisphosphate carboxylase(s)/oxygenase(s) (RuBisCO).

Ribose-1,5-bisphosphate is synthesized in a reaction that uses ribose-1(or 5)-P as the phosphoryl acceptor and the acyl-P of 3-phosphoglyceryl phosphate as the donor. Glucose-1,6-bisphosphate is synthesized in a similar reaction. The relative activity with the two substrates remains unchanged over

Ribose 1,5-bisphosphate (Rib-1,5-P2), a newly discovered activator of rat brain phosphofructokinase, forms rapidly during the initiation of glycolytic flux and disappears within 20 s (Ogushi, S., Lawson, J.W. R., Dobson, G.P., Veech, R.L., and Uyeda, K. (1990) J. Biol. Chem.

Macrophages can adapt to the absence of oxygen by switching to anaerobic glycolysis. In this study, we investigated (a) the roles of fructose 2,6-bisphosphate (Fru-2,6-P2) and ribose 1,5-bisphosphate (Rib-1,5-P2), potent activators of phosphofructokinase, (b) the enzymes responsible for the synthesis

The tissue contents of previously known allosteric effectors of brain phosphofructokinase (EC 2.7.1.11) (PFK) and the kinetic behavior of isolated PFK were investigated during the initiation of rapid glycolytic flux in freeze-blown rat brain. Comparing 0- with 5-s brains revealed

Fructose-1,6-bisphosphatase is one of the regulatory enzymes of gluconeogenesis in kidney cortex. The effect of ribose 1,5-bisphosphate on fructose-1,6-bisphosphatase purified from rat kidney cortex was studied. Rat kidney cortex, fructose-1,6-bisphosphatase exhibited hyperbolic kinetics with regard to its substrate, but the
