(a) Stereo representation of the superposition of the galactose-binding site I of ML-I in red and of ricin in blue as a ball-and-stick model. The bound lactose molecule is coloured red–orange in ML-I and blue in ricin. Hydrogen bonds are shown as red dashed lines for ML-I and in blue for ricin. Water molecules are marked as red circles in the ML-I complex and in blue in the ricin complex. (b) Superposition of galactose-binding site II of ML-I and ricin. The colour code is similar to (a). |
