Experiments have shown that serine residue in the carboxyterminal part of this enzyme has been conserved evolutionarily and accounts for some of the water-saving characteristics of the plants (*) in which it is highly concentrated.

Restricted to the mesophyll, where it is closer to the leaf surface, its activity is boosted by the presence of nitrate and it catalyzes a reaction which reduces oxaloacetate to malic acid. Unlike its analog, Rubisco, it has an extremely high affinity for CO2 and cannot fix oxygen. Thus, plants that utilize this enzyme have less photorespiratory carbon loss. FTP, name this plant enzyme that is used to fix carbon in CAM and C4 plants.
