This procedure is referred to as photorespiration and it occurs under conditions where the O concentration is high. During the daytime when there is sunlight present, the enzyme is turned on and at night Rubisco essay there is no light present, the enzyme is turned off.

The works cell so performs a dearly-won series of salvage reactions to rectify this. Some plants, many algae, and photosynthetic bacteria have overcome this limitation by devising means to increase the concentration of carbon dioxide around the enzyme, including C4 carbon fixationcrassulacean acid metabolismand the use of pyrenoid.

The center magnesium ion connects to a small sugar molecule, three amino acids, lysine, and carbon dioxide molecules.

Even though the geometry is octahedral, the molecule does not have an Oh symmetry if there are four long bonds and two short bonds for the six bonds present for the magnesium. Two of the oxygen atoms are from the sugar molecule and the other two are from the lysine. The process first makes a 4-carbon intermediate compound, which is shuttled into a site of C3 photosynthesis then de-carboxylated, releasing CO2 to boost the concentration of CO2, hence the name C4 plants.

When assaying moderately purified Rubisco, the RuBP-independent fixation is usually negligible.
