General annotation (Comments)

Catalytic activity	2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP MF_01133 3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP 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.5 Ref.4
Miscellaneous	The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation By similarity.
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 MF_01133
