Protein

Ribulose bisphosphate carboxylase small chain

Gene

rbcS4

Organism
Pteris vittata (Chinese ladder brake)
Status
Unreviewed-Annotation score: -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.UniRule annotation
