Figure 5
Stereo diagrams of the base-binding site. (a) AdoP–Ado–SO4 complex. (b) AdoP–Ino–SO4 complex. (c) D204N–Ado–SO4 complex. (d) D204N–Ino–SO4 complex. C atoms are shown in gray for the protein, in light blue for adenosine and in green for inosine. N atoms are shown in blue, O atoms in red and S atoms in yellow. Water molecules are shown as red spheres and labeled HOH. Hydrogen bonds are indicated by dashed lines and labeled with distances in Å. |
