Figure 7. (A) An FoKFc omit electron density map of the substrate DXP in the active site of DXR, contoured at 3s. The
position of the hydroxyl group in the L-configuration at C4 is depicted in green. (B) Hydrogen bonding interactions of
the substrate DXP in the active site of DXR. The position of the hydroxyl group in the L-configuration at C4 is depicted in
green. (C) A schematic diagram of the substrate DXP binding to DXR. For clarity, the bond between the carboxylate of
E231 and the hydroxyl group of C4 of DXP has been omitted.
