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.

Catalytic activity

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.

Subunit structure

8 large chains + 8 small chains.

Subcellular location

Plastidchloroplast.

Sequence similarities

Belongs to the RuBisCO small chain family.
