Protein
Ribulose bisphosphate carboxylase large chain 2
Gene
cbbL2, Nham_4049
Organism
Nitrobacter hamburgensis (strain X14 / DSM 10229)
Status
Reviewed - Annotation score: 3 out of 5 - 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 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.
