Topology and structure of the multi-drug-type ABC transporter Sav1866. (a) The topology of the TMD of a single TMD is shown, with an emphasis on the pseudo-twofold symmetry between the sets of TM helices 1–3 and 4–6. (b) The structure of the homodimeric Sav1866 is shown in ribbon representation, with the monomers in light and dark grey. (c) Sections through the Sav1866 are shown after rotating the protein by 90° from the view shown in (b), i.e. from the external side. TM helices of one monomer are numbered.
