This antibacterial action of daptomycin is correlated with the formation of membrane-associated oligomers. We here examine the number of subunits contained in one oligomer using fluorescence resonance energy transfer (FRET). The results suggest that the oligomer contains approximately 6 to 7 subunits, or possibly twice this number if it spans both membrane monolayers.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Antibiotic daptomycinBactericidal activityBindingDaptomycinEnergy-transferFluorescence resonance energy transferLipopeptide antibioticsOligomer stoichiometryStaphylococcus-aureusEstimation of the subunit stoichiometry of the membrane-associated daptomycin oligomer by FRETArticle
