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).

Irradiation of ribulose-1,5-bisphosphate carboxylase/oxygenase from spinach in the presence of vanadate at 4 degrees C resulted in rapid loss of carboxylase activity. The inactivation was light and vanadate dependent. When the enzyme was irradiated in the presence of the substrate

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 type III ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO) present in the archaeon Thermococcus kodakaraensis was found to participate in adenosine 5'-monophosphate (AMP) metabolism, a role that is distinct from that of classical RuBisCOs of the Calvin-Benson-Bassham cycle.
