Protein

Ribulose bisphosphate carboxylase small chain

Gene

POPTR_004G100000v3

Organism
Populus trichocarpa (Western balsam poplar) (Populus balsamifera subsp. trichocarpa)
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
3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2.UniRule annotationSAAS annotation
