The crystal structure of the binary complex of non-activated, ribulose-1,5-bisphosphate carboxylase/oxygenase from Rhodospirillum rubrum, and its product 3-phospho-D-glycerate has been determined to 2.9-A, resolution. This structure determination confirms the proposed location of, the active site (Schneider, G., Lindqvist, Y., Branden, C.-I., and, Lorimer, G. (1986) EMBO J. 5, 3409-3415) at the carboxyl end of the, beta-strands of the alpha/beta-barrel in the carboxyl-terminal domain. One, molecule of 3-phosphoglycerate is bound per active site. All oxygen atoms, of 3-phosphoglycerate form hydrogen bonds to groups of the enzyme. The, phosphate group interacts with the sidechains of residues Arg-288, His-321, and Ser-368, which are conserved between enzymes from different, species as well as with the main chain nitrogens from residues Thr-322 and, Gly-323. These amino acid residues constitute one of the two phosphate, binding sites of the active site. The carboxyl group interacts with the, side chains of His-287, Lys-191, and Asn-111. Implications of the, activation process for the binding of 3-phosphoglycerate are discussed.

== Function ==
 +
[https://www.uniprot.org/uniprot/RBL2_RHORU RBL2_RHORU] 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.[HAMAP-Rule:MF_01339]
