Molecular Tour
4D motif in TcAChE:
The 4 Asp residues, D326, D389, D392 and D393, are shown as sticks, with carbons in green, oxygens in red, and nitrogens in blue. Solvent waters are shown as blue spheres, and the metal ions as magenta spheres, with their sizes proportionate to their Van der Waals radii; the oxygens of the uranyl moiety are shown as red spheres. Non-covalent hydrogen bonds and ionic bonds are shown as dashed white lines.
