UniProt functional annotation for Q0INY7

UniProt code: Q0INY7.

Organism: Oryza sativa subsp. japonica (Rice).
Taxonomy: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliophyta; Liliopsida; Poales; Poaceae; BOP clade; Oryzoideae; Oryzeae; Oryzinae; Oryza.
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). {ECO:0000250}.
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.
Subcellular location: Plastid, chloroplast.
Miscellaneous: NADPH and 6-phosphogluconate function as positive effectors to promote enzyme activation. {ECO:0000305|PubMed:22609438}.
Similarity: Belongs to the RuBisCO small chain family. {ECO:0000305}.
Sequence caution: Sequence=CAA30393.1; Type=Frameshift; Positions=Several; Evidence={ECO:0000305}; Sequence=CAA30393.1; Type=Miscellaneous discrepancy; Note=Sequencing errors.; Evidence={ECO:0000305};
