ESR distances in bold represent the Rmax values from the distance distributions. The corresponding half width at full maximum (FWHM) is indicated in parenthesis. In cases where there are closely separated multiple peaks, a distance range is provided along with the Rmax of the major peak. Semicolons offset multiple groups of distances within the same distribution, with the dominant distance indicated in bold. Because ESR distances are typically longer than the C β separations, the model distances that satisfy the following criteria are reported: Rmax − 14 Å < Model distance < Rmax +5 Å for cases where FWHM is indicated. For the rest, the Rmax is replaced by the lower limit of distance range.
