Spinach Ribulose-1,5-Bisphosphat Carboxylase Oxygenase, 1aus
Template:STRUCTURE 1aus Rubisco (Ribulose-1,5-bisphosphate carboxylase oxygenase) EC 4.1.1.39, quite likely the most occurring enzyme of the world[1], is found also in plants and bacteria. It simplifies the first step in the Calvin-Benson-bassham-cycle: the catalytic binding of inorganic carbon dioxide to Ribulose-1,5-bisphosphate by a condensation reaction. The enzyme a hexadecamer with the molecular mass 550 kDa, consists out of 16 subunits (L8S8) which are divided into 8 large 50 – 55 kDa units and 8 small 12 – 18 kDa units. The genes which encode for the large subunits are located in the chloroplast whereas the genes for the small subunits are located in the nucleus.
