Anthrax toxin immobilization, translocation, and nanodisc stabilization (TITaNS) method (A) PApore side view slice with funnel shape from α clamp (yellow) to Φ clamp (orange) and charge clamp (red) inside pore β barrel channel indicated. (B) Immobilization of LFN (magenta) PAprepore (blue) complexes on thiol sepharose beads (grey surface). (C) PAprepore transitioned to PApore. (D) Predicted translocation complex of LFN -PApore at low pH. (E) Addition of pre-nanodisc micelle (green) to complex. (F) Nanodisc formation. (G) LFN-PApore-Nanodisc translocation complexes at pH 5.5 on cryoEM grid.
