In this study, we use nuclear magnetic resonance spectroscopy and molecular dynamics simulations to determine the unknown structure and evaluate the interaction with dodecylphosphatidylcholine (DPC) and sodium dodecylsulphate (SDS) micelles with three W6 -Hylin-a1 analogs antimicrobial peptides (HyAc, HyK, and HyD). The HyAc, HyK, and HyD bound to DPC micelles are all formed by a unique alpha-helix structure. Moreover, all peptides reach the DPC micelles' core, which thus suggests that the N-terminal modifications do not influence the interaction with zwiterionic surfaces. On the other hand, only HyAc and HyK peptides are able to penetrate the SDS micelle core while HyD remains always at its surface. The stability of the alpha-helical structure, after peptide-membrane interaction, can also be important to the second step of peptide insertion into the membrane hydrophobic core during permeabilization.
