The X-ray structure of the E2020-''Tc''AChE complex shows that E2020 has a <scene name='1eve/E2020_close_up_with_84_279/13'>unique orientation</scene> along the active-site gorge, extending from the anionic subsite (<scene name='1eve/E2020_close_up_with_84lbld/7'>W84</scene>) of the active site, at the bottom, to the peripheral anionic site (<scene name='1eve/E2020_close_up_with_84_279lbld/5'>near W279</scene>), at the top, via aromatic stacking interactions with conserved aromatic acid residues. E2020 does not, however, interact directly with either the catalytic triad or the 'oxyanion hole' but only <scene name='1eve/E20_interactionshown/8'>indirectly via solvent molecules</scene>. | The X-ray structure of the E2020-''Tc''AChE complex shows that E2020 has a <scene name='1eve/E2020_close_up_with_84_279/13'>unique orientation</scene> along the active-site gorge, extending from the anionic subsite (<scene name='1eve/E2020_close_up_with_84lbld/7'>W84</scene>) of the active site, at the bottom, to the peripheral anionic site (<scene name='1eve/E2020_close_up_with_84_279lbld/5'>near W279</scene>), at the top, via aromatic stacking interactions with conserved aromatic acid residues.
