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(+) = 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 ChEBI:CHEBI:58272; EC=4.1.1.39;
CC Evidence={ECO:0000256|ARBA:ARBA00001067,
CC ECO:0000256|RuleBase:RU000302};
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:0000256|ARBA:ARBA00000537,
CC ECO:0000256|RuleBase:RU000302};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
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}.
