ACTIVATED SPINACH RUBISCO IN COMPLEX WITH THE PRODUCT 3-PHOSPHOGLYCERATE
OverviewOverview
The crystal structure of an activated complex of ribulose-1,5-bisphosphate, carboxylase/oxygenase from spinach and its product 3-phosphoglycerate has, been determined to 2.2 A resolution. The structure is of the open form, with the active site accessible to the solvent as observed in the, structures of the activated ligand-free enzyme and the complex of the, activated enzyme with the substrate ribulose-1,5-bisphosphate. Two, molecules of 3-phosphoglycerate are bound per active site. The phosphates, of both molecules bind approximately at the same position as the, phosphates of ribulose-1,5-bisphosphate or the six-carbon intermediate, analogue 2-carboxyarabinitol-1,5-bisphosphate, but one product molecule is, swung out from the active site with its carboxylate group pointing toward, ...
