Protein existence	Evidence at protein level

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.
Subunit structure	Heterohexadecamer of 8 large chains and 8 small chains; disulfide-linked. The disulfide link is formed within the large subunit homodimers.
Subcellular location	Plastid › chloroplast HAMAP-Rule MF_01338.
Post-translational modification	The disulfide bond which can form between Cys-247 in the large chain dimeric partners within the hexadecamer appears to be associated with oxidative stress and protein turnover By similarity. The disulfide bond reported in 1IR2 may be the result of oxidation during crystallization. HAMAP-Rule MF_01338 The electron density found in the position of Thr-471 (Ref.6 only) suggests it is either O-methylthreonine, or Ile, which may be produced by RNA editing. 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". HAMAP-Rule MF_01338
Sequence similarities	Belongs to the RuBisCO large chain family. Type I subfamily.
