Fig. 2. a, schematic figure showing the main hydrogen bond interactions between UDP and 3GT residues at the catalytic site of the enzyme. The Mn2+ ion and water molecules are also shown. This image was created using the program MOLSCRIPT (38) and rendered using Raster3D (41). b, the location of UDP molecule in the active site tunnel. This image was created using the program DINO (A. Philippsen; available on the World Wide Web at www.dino3d.org).
