Spin–spin distance measurements in the inner cleft, with color codes referring to biochemical and structural states as defined in Figs. 1 and 3. (A) CW EPR spectra. A noninteracting control (single-Cys mutant) is shown in gray. Scan width, 200 G. (B) Distance distributions obtained by fitting CW EPR spectra, assuming a sum of multiple Gaussians. Arrows indicate distances between Cβ atoms in crystal structures.
