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 (By similarity).
CATALYTIC ACTIVITY: 2 3-phospho-D-glycerate + 2 H⁺ = D-ribulose 1,5-bisphosphate + CO₂ + H₂O.
CATALYTIC ACTIVITY: 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O₂.
SUBUNIT: 8 large chains + 8 small chains.
INTERACTION:
O04197:COI1; NbExp=2; IntAct=EBI-639640, EBI-401159;
SUBCELLULAR LOCATION: Plastid, chloroplast.
ALTERNATIVE PRODUCTS: 1 named isoform [FASTA] produced by alternative splicing. A number of isoforms are produced. According to EST sequences.

Name 1

Isoform ID P10798-1

This is the isoform sequence displayed in this entry.
MISCELLANEOUS: There are four genes coding for RBS in Arabidopsis thaliana.
SIMILARITY: Belongs to the RuBisCO small chain family.
