Comments

FUNCTION | RuBisCO catalyzes two reactions: the carboxylation of D- ribulose 1,5-bisphosphate, the primary event in carbon dioxide fixation, as well as the oxidative fragmentation of the pentose substrate. Both reactions occur simultaneously and in competition at the same active site. Although the small subunit is not catalytic it is essential for maximal activity. |
SUBUNIT | Heterohexadecamer of 8 large and 8 small subunits. |
SUBCELLULAR LOCATION | Plastid, chloroplast. |
MISCELLANEOUS | The basic functional RuBisCO is composed of a large chain homodimer in a 'head-to-tail' conformation. In form I RuBisCO this homodimer is arranged in a barrel-like tetramer with the small subunits forming a tetrameric 'cap' on each end of the 'barrel'. |
case not <AnyFeature:TransitC> | |
MISCELLANEOUS | This protein is expected to contain an N-terminal transit peptide but none has been predicted. |
end case | |
SIMILARITY | Belongs to the RuBisCO small chain family. |
