The mechanism of action of the antibacterial tripeptide AMC-109 is unclear. Here, Melcrová et al. show that AMC-109 self-assembles into stable aggregates with a cationic surface, and then individual peptides insert into the bacterial membrane and disrupt membrane nanodomains, thus affecting membrane function without forming pores.
