Protein attributes

Sequence length	139 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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.
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.
Sequence similarities	Belongs to the RuBisCO small chain family.
