Figure 4

Hypothetical FPP and IPP binding model with UPS. (A) Stereo view of the molecular surface of UPS (gray envelope) and the bindings of FPP and IPP (C, O, and P atoms in green, pink, and orange, respectively). The estimated position of the magnesium ion is shown by the brown sphere. This figure was prepared by using molscript (33), grasp (35), and raster3d (34). (B) Schematic presentation of a binding model. The UPS structure is shown in green.
