Protein

Ribulose bisphosphate carboxylase large chain

Gene

rbcL

Organism
Thiomonas arsenitoxydans (strain DSM 22701 / CIP 110005 / 3As)
Status
Unreviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O.UniRule annotation
3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2.UniRule annotation

Cofactori

Mg2+UniRule annotationNote: Binds 1 Mg2+ ion per subunit.UniRule annotation

Miscellaneousi

Miscellaneous

The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation. In form I RuBisCO this homodimer is arranged in a barrel-like tetramer with the small subunits forming a tetrameric "cap" on each end of the "barrel".UniRule annotation

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
