Fig. 1. Structure of the I. tartaricus c[11] ring in ribbon
representation. Subunits are shown in different colors. (A) View
perpendicular to the membrane from the cytoplasmic side. Two
subunits are labeled. (B) Side view. The blue spheres represent
the bound Na^+ ions. Detergent molecules inside the ring are
shown with red and gray spheres for clarity. The membrane is
indicated as a gray shaded bar (width, 35 Å). The images
were created with PyMOL (36).
