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 CC 1,5-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; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01338, ECO:0000256|RuleBase:RU000302}; CC -!- CATALYTIC ACTIVITY: CC Reaction=D-ribulose 1,5-bisphosphate + O2 = (2R)-3- CC phosphoglycerate + 2-phosphoglycolate + 2 H(+); CC Xref=Rhea:RHEA:36631, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, CC ChEBI:CHEBI:57870, ChEBI:CHEBI:58033, ChEBI:CHEBI:58272; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01338, CC ECO:0000256|RuleBase:RU000302}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01338, ECO:0000256|RuleBase:RU000302}; CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP- CC Rule:MF_01338, 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 CC subunit homodimers. {ECO:0000256|HAMAP-Rule:MF_01338}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP- CC Rule:MF_01338, ECO:0000256|RuleBase:RU000302}. CC -!- PTM: The disulfide bond which can form in the large chain dimeric CC partners within the hexadecamer appears to be associated with CC oxidative stress and protein turnover. {ECO:0000256|HAMAP- CC 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: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 CC of feature annotation. {ECO:0000256|HAMAP-Rule:MF_01338}.
