Figure 2.
Reversible complexes of 2PAM and HI6 with native and aged AChE. Crystal structures of HI6 bound to the active center gorge of A) native mouse AChE (pdb ID 2GYU, [11]) and B) aged mouse AChE at S203 (pdb ID 2WHQ, [12]). Crystal structures of 2PAM bound to the base of the active center gorge of C) native Topedo californica AChE (pdb ID 2VQ6, [13]) and D) aged Topedo californica AChE at S200 (pdb ID 2WG1, [14]). The oxime structures are shown as a stick model. The AChE active center gorge is represented by Connolly solvent accessible surface.
