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 in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site By similarity. HAMAP MF_01338 |
| Catalytic activity | 2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP MF_01338 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP MF_01338 |
| Cofactor | Binds 1 magnesium ion per subunit By similarity. HAMAP MF_01338 |
| Subunit structure | Heterohexadecamer of 8 large chains and 8 small chains; disulfide-linked. The disulfide link is formed within the large subunit homodimers By similarity. HAMAP MF_01338 |
| Subcellular location | |
| Post-translational modification | The disulfide bond which can form in the large chain dimeric partners within the hexadecamer appears to be associated with oxidative stress and protein turnover By similarity. HAMAP MF_01338 |
| Miscellaneous | The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation. In form I RuBisCO this homodimer is arranged in a barrel-like tetramer with the small subunits forming a tetrameric "cap" on each end of the "barrel" By similarity. HAMAP MF_01338 |
| Sequence similarities | Belongs to the RuBisCO large chain family. Type I subfamily. |
