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 in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site. HAMAP-Rule MF_01338

Catalytic activity

2 3-phospho-D-glycerate + 2 H+ = D-ribulose 1,5-bisphosphate + CO2 + H2O. HAMAP-Rule MF_01338

3-phospho-D-glycerate + 2-phosphoglycolate = D-ribulose 1,5-bisphosphate + O2. HAMAP-Rule MF_01338

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP-Rule MF_01338

Subunit structure

Heterohexadecamer of 8 large chains and 8 small chains; disulfide-linked. The disulfide link is formed within the large subunit homodimers By similarity.

Subcellular location

Plastidchloroplast HAMAP-Rule MF_01338.

Post-translational modification

The disulfide bond which can form in the large chain dimeric partners within the hexadecamer appears to be associated with oxidative stress and protein turnover By similarity. HAMAP-Rule MF_01338

Miscellaneous

The basic functional RuBisCO is composed of a large chain homodimer in a "head-to-tail" conformation. In form I RuBisCO this homodimer is arranged in a barrel-like tetramer with the small subunits forming a tetrameric "cap" on each end of the "barrel" By similarity.

Sequence similarities

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