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
CC       at the same active site. {ECO:0000255|HAMAP-Rule:MF_01338}.
CC   -!- CATALYTIC ACTIVITY: 2 3-phospho-D-glycerate + 2 H(+) = D-ribulose
CC       1,5-bisphosphate + CO(2) + H(2)O. {ECO:0000255|HAMAP-
CC       Rule:MF_01338}.
CC   -!- CATALYTIC ACTIVITY: 3-phospho-D-glycerate + 2-phosphoglycolate =
CC       D-ribulose 1,5-bisphosphate + O(2). {ECO:0000255|HAMAP-
CC       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-
CC       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
CC       RuBisCO this homodimer is arranged in a barrel-like tetramer with
CC       the small subunits forming a tetrameric "cap" on each end of the
CC       "barrel". {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}.
