General annotation (Comments)

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. Ref.5

Subunit structure

Homodecamer, consisting of fiver dimer units which form a ring-like pentagonal structure. This arrangement is essential for its high thermostability. Composed solely of large subunits. Ref.4 Ref.5

Miscellaneous

The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation By similarity. HAMAP-Rule MF_01133

Sequence similarities

Belongs to the RuBisCO large chain family. Type III subfamily.

Biophysicochemical properties

Temperature dependence:

Optimum temperature is 90 degrees Celsius. Highly thermostable. HAMAP-Rule MF_01133
