Top-ranked docking solutions between Fiu and the Fe–DHB substrate.
A, the location of the top-ranked docking modes in a cartoon representation of Fiu, for docking run 1 (R1M1), which includes the entire extracellular portion of the transporter, and docking run 2 (R2M1), in which the internal cavity is excluded from the search area. B, the same docking solutions as in A, with a cutaway composite view of Fiu.
