Protein

Ribulose bisphosphate carboxylase small chain 2

Gene

cbbS2

Organism
Allochromatium vinosum (strain ATCC 17899 / DSM 180 / NBRC 103801 / D) (Chromatium vinosum)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein 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.

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.

Caution

In C.vinosum two similar set of genes code for RuBisCO large and small chains: the RbcL-RbcS and the RbcA-RbcB sets. Under standard photoautotrophic culture conditions only the later set seems active, the former being probably cryptic.Curated
