Function
function
RuBisCO catalyzes two reactions: the carboxylation of D-ribulose 1,5-bisphosphate, the primary event in carbon dioxide fixation, as well as the oxidative fragmentation of the pentose substrate in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site.
Catalytic activity
- 2 (2R)-3-phosphoglycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O
- D-ribulose 1,5-bisphosphate + O2 = 2-phosphoglycolate + (2R)-3-phosphoglycerate + 2 H+
Cofactor
Note: Binds 1 Mg2+ ion per subunit.
