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: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   -!- 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: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       disulfide-linked. The disulfide link is formed within the large subunit
CC       homodimers. {ECO:0000255|HAMAP-Rule:MF_01338}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- PTM: The disulfide bond which can form in the large chain dimeric
CC       partners within the hexadecamer appears to be associated with oxidative
CC       stress and protein turnover. {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}.
