PAS-CNBh ring. Views from the cytosol of the PAS-CNBh domain rings: (a) structures after superposition of CNBh domains of rEAG (light green) and hERG (pink), (b) structures after superposition of the channels’ selectivity filters, and (c) side view of superposed channels through selectivity filter, showing PAS domains of rEAG and hERG rotated relative to each other while VSD domains are well-matched. Spheres indicate in Cα atom of equivalent residue in PAS domain of rEAG (P72) and hERG (E73). Arrows indicated relative displacement.
