Protein
Ribulose bisphosphate carboxylase small chain
Gene
cbbS
Organism
Nostoc sp. (strain PCC 7120 / SAG 25.82 / UTEX 2576)
Status
Functioni
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 (By similarity).By similarity
Miscellaneous
RuBisCO folding and assembly commences when the nascent large subunit folds with the help of chaperonin GroEL-GroES. Both RbcX and Raf1 help folded RbcL release from the chaperonin and dimerize; dimeric Raf1 binds to RbcL2 leading to an RbcL8-Raf18 complex. RbcS displaces Raf1, resulting in holoenzyme formation.1 Publication
