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. Although the
CC small subunit is not catalytic it is essential for maximal activity.

CC ECO:0000256|RuleBase:RU003627}.
CC -!- SUBUNIT: Heterohexadecamer of 8 large and 8 small subunits.
CC {ECO:0000256|HAMAP-Rule:MF_00859, ECO:0000256|RuleBase:RU003627}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP-
CC Rule:MF_00859}.
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'.
CC {ECO:0000256|HAMAP-Rule:MF_00859}.
CC -!- SIMILARITY: Belongs to the RuBisCO small chain family.
CC {ECO:0000256|HAMAP-Rule:MF_00859, ECO:0000256|RuleBase:RU003627}.
