WebLPS is a complex glycolipid, and probing its interactions with LPS transport (Lpt) proteins has been extremely challenging. However, mass spectrometry (MS) techniques have recently catalyzed tremendous advancements in the characterization of LPS transport (Lpt) proteins and probed associated conformational dynamics upon substrate binding. WebWe developed a native mass spectrometry-based approach to quantify the monomer–dimer equilibrium of the LPS transport protein LptH. We use this method to assess the potency and efficacy of an antimicrobial peptide and small molecule disruptors, obtaining new information on their structure–activity relationships.
