Figure 5
Stereoview ball-and-stick diagram showing the two HSO4- ion-binding sites in the DPI_HAc crystal structure. HSO4- ions are coloured yellow, adjacent DPI_HAc dimers in the crystal are coloured either grey or black with white atoms and water molecules are represented by red spheres. Hydrogen bonds between one of the HSO4- ions and atoms of the A-chain N-terminus are shown as dashed lines. This figure was produced using BobScript (Esnouf, 1997). |
