Fig. 3: Comparison of the selectivity filter and central cavity of hEag2 in six states.
From: Mechanism underlying delayed rectifying in human voltage-mediated activation Eag2 channel
a–f Selectivity filter and central cavity of hEag2 in closed state 1 in yellow (a), closed state 2 in orange (b), pre-open state 1 in slate (c), pre-open state 2 in blue (d), open state in green (e) and pore dilation but non-conducting state in cyan (f) shown, viewed from within the membrane. Water molecules above the selectivity filter are shown as red spheres and the potassium ions in S0–S6 are shown as purple spheres with electron density maps (purple mesh).
