Ligands: CAP, FMT, MG Activity: Ribulose-bisphosphate carboxylase, with EC number 4.1.1.39 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [RBL_SYNP6] 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] [RBS_SYNP6] 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.

Publication Abstract from PubMed The structure of an activated quaternary complex of ribulose 1,5-bisphosphate carboxylase/oxygenase (rubisco) from Synechococcus PCC6301 has been solved by molecular replacement. The protein crystallizes in an orthorhombic P2(1)2(1)2(1) unit cell with a complete L(8)S(8) complex consisting of 4608 residues (37 680 non-hydrogen atoms) in the asymmetric unit. Data were collected both on film and image plate using synchrotron radiation; there were 218 276 unique reflections in the final 2.2 A data set. The eightfold non-crystallographic symmetry could be used both to improve map quality and to reduce the computing requirements of refinement. The coordinates were refined using strict non-crystallographic symmetry constraints. The stereochemistry of the final model is good, and the model has an R value of 20.0% for the reflections between 7 and 2.2 A.
