The antimicrobial peptide microcin J25 stabilizes the gel phase of bacterial model membranes

- Microcin J25 is an antimicrobial with multiple molecular targets in sensitive cells.
- The peptide membrane interaction was assayed both in lipid monolayers and bilayers.
- The peptide stabilized ordered states in membranes.
- Condensed domains formation was enhanced upon microcin J25 adsorption in monolayers.
