General annotation (Comments)

Function

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 By similarity. HAMAP-Rule MF_01133

Catalytic activity

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP-Rule MF_01133

3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP-Rule MF_01133

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP-Rule MF_01133

Subunit structure

Homodimer or homodecamer. In contrast to form I RuBisCO, the form III RuBisCO is composed solely of large subunits By similarity. HAMAP-Rule MF_01133

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 (PubMed:17303759) By similarity. HAMAP-Rule MF_01133

Sequence similarities

Belongs to the RuBisCO large chain family. Type III subfamily. HAMAP-Rule MF_01133
