A molecular model is proposed for the transmembrane channels formed by alamethicin and related polypeptides. The channels consist of an aggregate of rod-like helical polypeptides with a central aqueous core of ordered water. The helix dipole moment is considered to be the major factor modulating channel size, selectivity and field-dependent transitions.
