LFN helix α1 separates from helix α2 and binds in PA α-clamp. (Left) Black—additive spectra of LFN Inline graphic E60R1. Red—Spectrum of LFN M40R1/E60R1 alone. (Right) Black—additive spectrum of LFN M40R1 with WT Inline graphic E60R1 with WT PA. Red—Spectrum of LFN M40R1/E60R1 with WT PA. Spectra were collected at pH 8.5 (when PA is in the prepore state) and normalized to the total number of spins.
