Figure 1.
The energy-minimized model of DAT-DA-cocaine complex structure. (A) Side view along the normal of the membrane. (B) Top view of the complex structure. The DAT-DA protein is represented as colored ribbons. Na+ ions are shown in cyan spheres, and Cl− ion in red sphere. Dopamine (DA) is shown in space-filled spheres and colored in blue. Cocaine molecule (COC) in the complex is shown in space-filled spheres and colored gray. Also labeled are the EL-2, TM12, and the membrane position.
