O98948

- RBS_THANO

UniProt

O98948 - RBS_THANO

Protein

Ribulose bisphosphate carboxylase small chain

Gene

rbcS

Organism
Thalassiosira nordenskioeldii (Marine diatom)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi
  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.
