at 4°C, using the hanging-drop vapor-diffusion method. SDH both in its ligand-free form and in complex with shikimate. Overall structure of apo-SDH is basically identical to that of the shikimate-SDH complex, both structures contain one molecule per asymmetric unit. Overall folding of SDH comprises the N-terminal alpha/beta domain for substrate binding and the C-terminal Rossmann fold for NADP binding. The active site is within a large groove between the two domains. Residue Tyr211 does not interact with shikimate in the binary SDH-shikimate complex structure. The main function of Tyr211 may be to stabilize the catalytic intermediate during catalysis. The NADP-binding domain of SDH is less conserved. The long helix specifically recognizing the adenine ribose phosphate is substituted with a short 310 helix in the NADP-binding domain. The interdomain angle of SDH is the widest among all known SDH structures, indicating an inactive open state of the SDH structure. Thus, a closing process may occur upon NADP+ binding to bring the cofactor close to the substrate for catalysis
determination of the crystal structure at 1.45 A by molecular replacement. The protein shows a monomeric architecture. The overall structure comprises the N-terminal alpha/beta sandwich domain for substrate binding and the C-terminal domain for NADP binding.the enzyme is in a tightly closed conf ormation, which should be open for catalysis. Four ammonium sulfate ions were identified in the structure. They are located in the active site and appear to mimic the role of the substrate in terms of the enzyme activity and stability
