Because the N-terminus is very constricted near Val27, the M2 channel is highly selective for protons. | Because the N-terminus is very constricted near Val27, the M2 channel is highly selective for protons. The restricted N-terminus only allows protons to penetrate into the aqueous pore through hydrogen-bonded chains of water. Therefore, it would be extremely difficult for hydrated sodium or potassium to penetrate the restricted areas of the M2 channel.<ref name="Stouffer" /> | ||
