Both reactions occur simultaneously and in competition at the same active site (By similarity).CATALYTIC ACTIVITY:2 3-phospho-D-glycerate 2 H() = D-ribulose 1,5-bisphosphate CO(2) H(2)O.CATALYTIC ACTIVITY:3-phospho-D-glycerate 2-phosphoglycolate = D-ribulose 1,5-bisphosphate O(2).COFACTOR:Binds 1 magnesium ion per subunit (By similarity).SUBUNIT:Homodimer (By similarity).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).MISCELLANEOUS:This protein is suggested in Ref.1 to be first co- translationally imported into the ER up to the stop-transfer signal, so that the N-terminal region of the transit peptide is in the lumen of the ER while the rest of the protein remains in the cytoplasm. Maintaining this topology, proteins are directed to the Golgi and sorted into vesicles that will fuse with the outermost plastid membrane, exposing the transit peptide to the Toc/Tic apparatus, which draws the entire protein across the remaining membranes.SIMILARITY:Belongs to the RuBisCO large chain family. Type II subfamily.CAUTION:Note that unlike other eukaryotes, peridinin-containing dinoflagellates have a nuclear-encoded chloroplast-targeted form II RuBisCO."
