The voltage-sensor structure in a voltage-gated channel.
A recent electron paramagnetic resonance study of KvAP, a prokaryotic voltage-gated channel, in its lipid native environment has revealed the location of the transmembrane segments, the connecting loops and the relative position of the voltage-sensing charges. The results confirm that the previously reported crystal structure does not represent a native conformation and give us structural constraints that will help in determining the molecular structure of the voltage sensor.
