  • 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 NADPH and 6-phosphogluconate function as positive effectors to promote enzyme activation.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'.SIMILARITY Belongs to the RuBisCO small chain family.SEQUENCE CAUTION Sequencing errors.
