Here the X-ray crystal structures of the Drosophila dopamine transporter bound to dopamine, D-amphetamine, methamphetamine and cocaine are solved; these structures show how a neurotransmitter, small molecule stimulants and cocaine bind to a biogenic amine transporter, and are examples of how the ligand binding site of a neurotransmitter transporter can remodel itself to accommodate structurally unrelated small molecules that are different in shape, size and polarity or charge.
