P23756

- RBS_GALSU

UniProt

P23756 - RBS_GALSU

Protein

Ribulose bisphosphate carboxylase small chain

Gene

rbcS

Organism
Galdieria sulphuraria (Red alga)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli
  1. 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.
