Position and motions of the S4 helix during opening of the Shaker potassium channel
The four voltage sensors in voltage-gated potassium (Kv) channels activate upon membrane depolarization and open the pore. The location and motion of the voltage-sensing S4 helix during the early activation steps and the final opening transition are unresolved. We studied Zn(2+) bridges between two...
