ESR distances in bold represent the R_max 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 R_max 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: R_max − 14 Å < Model distance < R_max +5 Å for cases where FWHM is indicated. For the rest, the R_max is replaced by the lower limit of distance range.
