Protein

Ribulose bisphosphate carboxylase small chain

Gene

rbcs

Organism
Brassica juncea (Indian mustard) (Sinapis juncea)
Status
Unreviewed-Annotation score: -Experimental evidence at transcript 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.UniRule annotation

Catalytic activityi

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