The Dual Mode of Antibacterial Action of the Synthetic Small Molecule DCAP Involves Lipid II Binding

The synthetic small molecule DCAP is a chemically well-characterized compound with antibiotic activity against Gram-positive and Gram-negative bacteria, including drug-resistant pathogens. Until now, its mechanism of action was proposed to rely exclusively on targeting the bacterial membrane, thereby causing membrane depolarization, and increasing membrane permeability (Eun
