Parameters for the fit to the REDOR dephasing of Figures 4 (N{F}) and 6 (C{F}) as a function of dipolar evolution time for double-labeled plusbacin A₃ (blue numbers from Figures 4 and 6) and double-labeled deslipo-plusbacin A₃ (red numbers from Figures 4 and 6) bound to the cell walls of whole cells of S. aureus grown in media containing [1-¹³C]glycine, as a function of dipolar evolution time for a single distance (left, white background), and for a bimodal Gaussian distribution of distances (right, shaded background). The parameter s is the asymptotic dephasing limit, χ² is a mean-square measure of the deviation of experimental and calculated dephasing, σ is a Gaussian distribution width, and f is the fractional contribution of component 1 (where that of component 2 is 1 − f). The numbers in gray were fixed. See the text (Materials and Methods) for an explanation of the statistical F-test (right-most column) and the critical F-distribution numbers given as footnotes to the table.
