Protein

Ribulose bisphosphate carboxylase

Gene

rbcL

Organism
Natronomonas pharaonis (strain ATCC 35678 / DSM 2160) (Halobacterium pharaonis)
Status
Unreviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the addition of molecular CO2 and H2O to ribulose 1,5-bisphosphate (RuBP), generating two molecules of 3-phosphoglycerate (3-PGA). Functions in an archaeal AMP degradation pathway, together with AMP phosphorylase and R15P isomerase.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

Binds 1 magnesium ion per subunit.UniRule annotation

Miscellaneousi

Miscellaneous

Because the Archaea possessing a type III RuBisCO are all anaerobic, it is most likely that only the carboxylase activity of RuBisCO, and not the competitive oxygenase activity (by which RuBP reacts with O2 to form one molecule of 3-phosphoglycerate and one molecule of 2-phosphoglycolate), is biologically relevant in these strains.UniRule annotation
