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. HAMAP MF_01339
Catalytic activity	2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP MF_01339 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP MF_01339
Cofactor	Binds 1 magnesium ion per subunit By similarity. HAMAP MF_01339
Subunit structure	Homodimer By similarity. HAMAP MF_01339
Miscellaneous	The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation. In contrast to form I RuBisCO, the form II RuBisCO are composed solely of large subunits By similarity. HAMAP MF_01339
Sequence similarities	Belongs to the RuBisCO large chain family. Type II subfamily.
