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 By similarity. RuleBase RU003627 SAAS SAAS000894
Catalytic activity	2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. RuleBase RU003627 SAAS SAAS000894 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. RuleBase RU003627 SAAS SAAS000894
Subunit structure	8 large chains + 8 small chains By similarity. RuleBase RU003627 SAAS SAAS000894
Sequence similarities	Belongs to the RuBisCO small chain family. RuleBase RU003627
