CC   -!- FUNCTION: RuBisCO catalyzes two reactions: the carboxylation of D-
CC       ribulose 1,5-bisphosphate, the primary event in carbon dioxide
CC       fixation, as well as the oxidative fragmentation of the pentose
CC       substrate. Both reactions occur simultaneously and in competition at
CC       the same active site. {ECO:0000255|HAMAP-Rule:MF_01338}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 (2R)-3-phosphoglycerate + 2 H(+) = CO2 + D-ribulose 1,5-
CC         bisphosphate + H2O; Xref=Rhea:RHEA:23124, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57870,

CC         Rule:MF_01338};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-ribulose 1,5-bisphosphate + O2 = (2R)-3-phosphoglycerate +
CC         2-phosphoglycolate + 2 H(+); Xref=Rhea:RHEA:36631, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:57870, ChEBI:CHEBI:58033,
CC         ChEBI:CHEBI:58272; Evidence={ECO:0000255|HAMAP-Rule:MF_01338};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01338};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01338};
CC   -!- SUBUNIT: Heterohexadecamer of 8 large chains and 8 small chains.
CC       {ECO:0000255|HAMAP-Rule:MF_01338}.
CC   -!- MISCELLANEOUS: The basic functional RuBisCO is composed of a large
CC       chain homodimer in a 'head-to-tail' conformation. In form I RuBisCO
CC       this homodimer is arranged in a barrel-like tetramer with the small
CC       subunits forming a tetrameric 'cap' on each end of the 'barrel'.
CC       {ECO:0000255|HAMAP-Rule:MF_01338}.
CC   -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type I
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01338}.
