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|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 ChEBI:CHEBI:58272; EC=4.1.1.39; CC Evidence={ECO:0000256|ARBA:ARBA00001067, ECO:0000256|HAMAP- CC Rule:MF_01338, 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|HAMAP-Rule:MF_01338, ECO:0000256|RuleBase:RU000302}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01338, CC ECO:0000256|RuleBase:RU000302}; CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01338, CC ECO:0000256|RuleBase:RU000302}; CC -!- SUBUNIT: Heterohexadecamer of 8 large chains and 8 small chains. CC {ECO:0000256|ARBA:ARBA00011371, ECO:0000256|HAMAP-Rule:MF_01338, CC ECO:0000256|RuleBase:RU000302}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP- CC Rule:MF_01338, ECO:0000256|RuleBase:RU000302}. 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:0000256|HAMAP-Rule:MF_01338}. CC -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type I CC subfamily. {ECO:0000256|HAMAP-Rule:MF_01338}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01338}.
