General annotation (Comments)

Function

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. HAMAP MF_01338

Catalytic activity

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP MF_01338

3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP MF_01338

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP MF_01338

Subunit structure

Heterohexadecamer of 8 large chains and 8 small chains By similarity.

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. HAMAP MF_01338

Sequence similarities

Belongs to the RuBisCO large chain family. Type I subfamily.

Caution

In T.ferroxidans two similar set of genes code for RuBisCO large and small chains: the rbcL1-rbcS1 and the rbcL2-rbcS2 sets.
