UniProt functional annotation for P00873

UniProt code: P00873.

Organism: Chlamydomonas reinhardtii (Chlamydomonas smithii).
Taxonomy: Eukaryota; Viridiplantae; Chlorophyta; Chlorophyceae; Chlamydomonadales; Chlamydomonadaceae; Chlamydomonas.
 
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. {ECO:0000269|PubMed:11641402}.
Subcellular location: Plastid, chloroplast.
Similarity: Belongs to the RuBisCO small chain family. {ECO:0000305}.
Sequence caution: Sequence=CAA28159.1; Type=Erroneous initiation; Evidence={ECO:0000305};
