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). {ECO:0000250}.
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   -!- SUBUNIT: 8 large chains + 8 small chains.
CC   -!- SIMILARITY: Belongs to the RuBisCO small chain family.
CC       {ECO:0000305}.
