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. Both reactions occur simultaneously and in competition
CC       at the same active site (By similarity).
CC   -!- CATALYTIC ACTIVITY: 2 3-phospho-D-glycerate + 2 H(+) = D-ribulose
CC       1,5-bisphosphate + CO(2) + H(2)O.
CC   -!- CATALYTIC ACTIVITY: 3-phospho-D-glycerate + 2-phosphoglycolate =
CC       D-ribulose 1,5-bisphosphate + O(2).
CC   -!- COFACTOR: Binds 1 magnesium ion per subunit (By similarity).
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- MISCELLANEOUS: The basic functional RuBisCO is composed of a large
CC       chain homodimer in a "head-to-tail" conformation. In contrast to
CC       form I RuBisCO, the form II RuBisCO are composed solely of large
CC       subunits (By similarity).
CC   -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type II
CC       subfamily.
