Abstract:
Antimicrobial resistance is a global health threat, calling for new antibiotics. Good candidates could be peptide-based compounds that target special lipids that only exist in bacterial, but not in human cell membranes. These drugs kill pathogens without detectable resistance, which has generated considerable interest.
Here, using an integrative structural biology approach, we show that drugs that target special lipids in bacterial membranes use sophisticated supramolecular killing mechanisms1-3.
