Protein

Ribulose bisphosphate carboxylase small chain, chloroplastic

Gene

RBCS

Organism
Glycine tabacina
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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

Catalytic activityi

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O.
3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2.
