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 (By
CC similarity). {ECO:0000250}.
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 -!- 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;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250};
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 (By similarity). {ECO:0000250}.
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:0000250}.
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' (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type I
CC subfamily. {ECO:0000305}.
