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   -!- SUBUNIT: 8 large chains + 8 small chains.
CC   -!- INTERACTION:
CC       Q9ZPS9:BRL1; NbExp=1; IntAct=EBI-639640, EBI-2292728;
CC       O04197:COI1; NbExp=2; IntAct=EBI-639640, EBI-401159;
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=1;
CC         Comment=A number of isoforms are produced. According to EST
CC         sequences;
CC       Name=1;
CC         IsoId=P10798-1; Sequence=Displayed;
CC   -!- MISCELLANEOUS: There are four genes coding for RBS in Arabidopsis
CC       thaliana.
CC   -!- SIMILARITY: Belongs to the RuBisCO small chain family.
