DESCRIPTION

Also known as RBL_PEA, rbcL. 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 (Probable). Binds to abscisic acid (ABA); only half of the possible binding sites are occupied in the crystal and there are indications this is a low affinity site (PubMed:26197050). Heterohexadecamer of 8 large chains and 8 small chains (PubMed:23295478). Heterohexadecamer; disulfide-linked. The disulfide link is formed within the large subunit homodimers (PubMed:26197050).
