Protein

Ribulose bisphosphate carboxylase small chain

Gene
OSTLU_42060
Organism
Ostreococcus lucimarinus (strain CCE9901)
Status
Unreviewed - Annotation score: 2 out of 5 - 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.UniRule annotationSAAS annotations

Catalytic activityi

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