Mode of Action of Teixobactin in cellular membranes

Teixobactin, heralded as game-changer drug, could be one of our sharpest weapons against multi-drug resistant bacteria, however, before could use it in clinics, it requires chemical modifications.

Here we show the mode of action of teixobactin in cell membranes, including a HR structure, which could enable scientists worldwide to unlock the enormous potential of teixobactin for clinical applications.
