RuBisCO-RuBP complex. Computer model showing the active site of a molecule of the carbon fixation enzyme ribulose-1, 5-bisphosphate carboxylase oxygenase (RuBisCO), from a spinach plant (Spinacia oleracea), in complex with a molecule of its natural substrate ribulose 1, 5-bisphosphate (RuBP, red) in its transition state, and a Mg2+ magnesium ion (green). RuBisCO is an enzyme that aids carbon fixation - the conversion of inorganic carbon from forms such as carbon dioxide to organic compounds by living organisms in processes such as photosynthesis. It is a hexadecamer composed of 8 heavy catalytic subunits (blue and white ribbons) and 8 light regulatory subunits (yellow and orange). The Mg2+ ion is critical for the process of fixing carbon from carbon dioxide. | |
