UniProt functional annotation for P04716

UniProt code: P04716.

Organism: Synechococcus sp. (strain ATCC 27144 / PCC 6301 / SAUG 1402/1) (Anacystis nidulans).
Taxonomy: Bacteria; Cyanobacteria; Oscillatoriophycideae; Chroococcales; Synechococcus.
 
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 + CO(2) + H(2)O.
Catalytic activity: 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O(2).
Subunit: 8 large chains + 8 small chains.
Similarity: Belongs to the RuBisCO small chain family.
