General annotation (Comments)
| 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. Both reactions occur simultaneously and in competition at the same active site. |
| Catalytic activity | 2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. |
| Subunit structure | 8 large chains + 8 small chains. |
| Subcellular location | |
| Sequence similarities | Belongs to the RuBisCO small chain family. |
