Dissociation of Ribulose-1,5-Bisphosphate Bound to Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase and Its Enhancement by Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Activase-Mediated Hydrolysis of ATP [PDF]
Ribulose bisphosphate (RuBP), a substrate of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), is an inhibitor of Rubisco activation by carbamylation if bound to the inactive, noncarbamylated form of the enzyme. The effect of Rubisco activase on the dissociation kinetics of RuBP bound to this form of the enzyme was examined and characterized ...

An ancient metabolite damage-repair system sustains photosynthesis in plants
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the major catalyst in the conversion of carbon dioxide into organic compounds in photosynthetic organisms. However, its activity is impaired by binding of inhibitory sugars such as xylulose-1,5-

Exploring the oxygenase function of Form II Rubisco for production of glycolate from CO2
The oxygenase activity of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) converts ribulose-1,5-bisphosphate (RuBP) into 2-phosphoglycolate, which in turn channels into photorespiration, resulting in carbon and energy loss in higher plants.

Light-dependent assembly of ribulose-1,5-bisphosphate carboxylase [PDF]
Ribulose-1,5-bisphosphate carboxylase [Ru P 2 Case; 3-phospho-D-glycerate carboxy-lyase (dimerizing), EC 4.1.1.39] is composed of eight small subunits ( M r , 14,000) and eight large subunits ( M r , 55,000).

Competition of Pyridoxal 5'-Phosphate with Ribulose 1,5-Bisphosphate and Effector Sugar Phosphates at the Reaction Centers of the Spinach Ribulose 1,5-Bisphosphate Carboxylase/Oxygenase [PDF]
The Stimulation of the carboxylase reaction by effectors of ribulose 1,5-bisphosphate carboxyl ase/oxygenase displays higher sensitivity towards pyridoxal 5'-phosphate inhibition than the catalytical process itself. Pyridoxal 5'-phosphate binding to the

Molecular mechanism of Rubisco activase: Dynamic assembly and Rubisco remodeling
Ribulose-1,5-bisphosphate (RuBP) carboxylase-oxygenase (Rubisco) enzyme is the limiting step of photosynthetic carbon fixation, and its activation is regulated by its co-evolved chaperone, Rubisco activase (Rca). Rca removes the intrinsic sugar phosphate

Protein transport in intact, purified pea etioplasts [PDF]
We have developed a method to isolate intact, purified pea etioplasts. These etioplasts were capable of recognizing, transporting, and processing the precursor form of the small subunit of the ribulose-1,5-bisphosphate carboxylase, a protein which is not
