Mycobacteria import life-essential iron using capturing molecules called mycobactins. In this work, the authors uncover how an ATP-fuelled transporter imports mycobactin across the inner membrane in an unusual “credit card” mechanism, during which mycobactin slides down a crevice at the transporter surface.
