UniProt functional annotation for P45686

UniProt code: P45686.

Organism: Halothiobacillus neapolitanus (strain ATCC 23641 / c2) (Thiobacillus neapolitanus).
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Chromatiales; Halothiobacillaceae; Halothiobacillus.
 
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.
