Protein
Ribulose bisphosphate carboxylase large chain
Gene
cbbL, rbcL, Dacsa_1767
Organism
Dactylococcopsis salina PCC 8305
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

Miscellaneousi

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
