Abstract

To facilitate microbial membrane invasion, amphiphilic α-helical antimicrobial peptides (α-AMPs) show a spatial segregation of hydrophobic and hydrophilic residues about the α-helical long axis. Here we discuss potential mechanisms by which these peptides are able to disrupt membrane structure and the structural characteristics, which are required for function.

Keywords: antimicrobial peptides, amphiphilicity, microbial membranes
