Glycine position permutations and peptide length alterations change the aggregation state and efficacy of ion-conducting, pore-forming amphiphiles.
Changes in the peptide chain of amphiphilic heptapeptides known to form ion-conducting pores in bilayers dramatically alter transport efficacy and the aggregation number of pore formation.
