General annotation (Comments)

Function

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 By similarity. HAMAP-Rule MF_01339

Catalytic activity

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP-Rule MF_01339

3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP-Rule MF_01339

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP-Rule MF_01339

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_01339

Miscellaneous

The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation. In contrast to form I RuBisCO, the form II RuBisCO are composed solely of large subunits By similarity.

Sequence similarities

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