a, Close-up view of Sav1866 with one subunit in turquoise ribbon representation, the other in yellow coil representation. For clarity, only the ICL regions of the transmembrane domains are shown. Black spheres depict the first and last C positions of the 'coupling helices' (see the text). Side chains of the conserved Glu 473 and Tyr 391 are in ball-and-stick representation. b, Alignment of the Sav1866 protein sequence with those of other ABC transporters. Residues with high conservation are shaded dark grey, those with significant conservation are shaded light grey, and relevant motifs are shaded blue and indicated. Residues of the ICLs interacting (4 Å cut-off) with the NBD of the same subunit are indicated with green shading, and those contacting the opposite NBD with yellow shading. Residues of the NBD interacting with the TMD are shown with red shading.
