Figure 3.
Fig. 3. The ligand-binding site of GluR2-S1S2J. A: Interactions between GluR2-S1S2J and (S)-Des-Me-AMPA. Dashed lines indicate potential hydrogen bonds/ionic interactions (up to 3.3 Å). Water molecules are displayed as red spheres. Nitrogen atoms are shown in blue, oxygen atoms in red, and sulfur atoms in dark green. B: Superimposition of the (S)-Des-Me-AMPA (cyan), (S)-AMPA (green), (S)-2-Me-Tet-AMPA (magenta) and (S)-glutamate (yellow) complexes (shown in stereo). For all structures MolA is used as a representative. The conformation of Met708 in the glutamate complex is unique for MolA, as the other two molecules have extended Met708 chains.
