== Publication Abstract from PubMed ==
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.
