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...

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...

Decaprenylphosphoryl-d-arabinose (DPA) has been shown to be the donor of the essential d-arabinofuranosyl residues found in the cell wall of Mycobacterium tuberculosis. DPA is formed from phosphoribose diphosphate in a four-step process. The first step is the nucleophilic replacement of...

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. Genes annotated as thymidine phosphorylase...
