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 in the photorespiration process. Both reactions occur
CC       simultaneously and in competition at the same active site.
CC       {ECO:0000256|ARBA:ARBA00025664}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 (2R)-3-phosphoglycerate + 2 H(+) = D-ribulose 1,5-
CC         bisphosphate + CO2 + H2O; Xref=Rhea:RHEA:23124, ChEBI:CHEBI:15377,

CC         Evidence={ECO:0000256|RuleBase:RU000302};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|RuleBase:RU000302};
CC   -!- SUBUNIT: Heterohexadecamer of 8 large chains and 8 small chains;
CC       disulfide-linked. The disulfide link is formed within the large subunit
CC       homodimers. {ECO:0000256|ARBA:ARBA00025888}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast
CC       {ECO:0000256|RuleBase:RU000302}.
CC   -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type I
CC       subfamily. {ECO:0000256|ARBA:ARBA00006204}.
