Snapshots of the voltage-sensor domain (A–D) taken from SMD simulations of the full tetrameric channel. During the simulation, the salt-bridge between E0 (S1) and R1 (S4) is broken, and a new salt-bridge is formed between E1 (S2) and R1 on S4. Time-dependent variations of the displacement charge Qd of the isolated VSD (E) and the full tetrameric channel (F) during SMD simulations. Blue lines represent Qd values calculated at every 10 ps in each trajectory. The thick black lines represent the Qd values block-averaged over every 300 ps.
