Protein
Ribulose bisphosphate carboxylase large chain
Gene
cbbL, rbcL, Sta7437_0333
Organism
Stanieria cyanosphaera (strain ATCC 29371 / PCC 7437)
Status
Unreviewed - Annotation score: 4 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 in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site By similarity.UniRule annotation

Catalytic activityi

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O.UniRule annotation
3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2.UniRule annotation

Cofactori

Binds 1 magnesium ion per subunit By similarity.UniRule annotation

Miscellaneous

The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation. In form I RuBisCO this homodimer is arranged in a barrel-like tetramer with the small subunits forming a tetrameric "cap" on each end of the "barrel" By similarity.UniRule annotation
