Protein

Ribulose bisphosphate carboxylase small chain 3A, chloroplastic

Gene

RBCS-3A

Organism
Pisum sativum (Garden pea)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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.
