Abstract:Antimicrobial resistance is one of the leading concerns in medical care. Here we resolve the functional mechanism of the antimicrobial action of the cationic tripeptide AMC-109 by combining high speed-atomic force microscopy, molecular dynamics, fluorescence assays, and lipidomic analysis. We show that AMC-109 activity on the negatively charged plasma membrane of Staphylococcus aureus consists of two crucial steps. First, AMC-109 self-assembles into stable aggregates with specificity for negatively charged mem… Show more
