Figure 6. Inhibition mechanism.
(A) Scheme of the inhibitor binding to the outward-facing cavity of an SLC11 transporter thereby preventing substrate binding and conformational changes. (B) Interactions of the transported ion and different inhibitors with the outward-facing cavity of EcoDMT and hDMT1. The shape of the cavity is indicated, the sidechain of the conserved aspartate of the metal ion binding site and the chemical structures of different inhibitors are shown.
