Fig. 2. — LF_N residues 2, 5, and 10 interact with PA pore. Shown are EPR spectra of spin-labeled LF_N variants with and without WT PA. Black line—LF_N alone. Red line—with WT PA (1∶1 molar ratio heptamer). (Left) Spectra collected at pH 8.5 (when PA is in the prepore conformation). (Right) Spectra collected at pH 5.5 (when PA is in the pore conformation). Spectra were collected at room temperature and normalized to the intensity of the central peak.
