Protein

Ribulose bisphosphate carboxylase small chain SSU5A, chloroplastic

Gene

SSU5A

Organism
Lemna gibba (Swollen duckweed)
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

Miscellaneous

This protein is coded by one member of a small multigene family.

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.
