Figure 1. Structure of CLC-ec1. (a) Ribbon representation of
the homodimer, with the two subunits colored in red and gray and
the extracellular side on top. Green spheres represent Cl^−
ions at the inner and central positions. (b) The Cl^− binding
region in a view similar to (a). Atoms of the protein backbone
(N, C, CA) and selected side-chains are shown. The two
H^+-transfer glutamate side-chains are highlighted in yellow.
The Cl^− ions bound to the inner and central' site are shown
as green spheres. The three ion binding sites are labeled.
Putative trajectories for Cl^− (green) and H^+ (red) are shown
as broken curves. Figure 1. Structure of CLC-ec1. (a) Ribbon
