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. HAMAP-Rule MF_01338 |
| Catalytic activity | 2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP-Rule MF_01338 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP-Rule MF_01338 |
| Cofactor | Binds 1 magnesium ion per subunit By similarity. |
| Subunit structure | Heterohexadecamer of 8 large chains and 8 small chains By similarity. |
| 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-Rule MF_01338 |
| Sequence similarities | Belongs to the RuBisCO large chain family. Type I subfamily. |
| Biophysicochemical properties | Kinetic parameters: The CO2/O2 specificity factor (tau) is 75. KM=55 µM for ribulose 1,5-bisphosphate Ref.1 KM=66 µM for CO2 Vmax=2.8 µmol/min/mg enzyme with CO2 as substrate |
