NPRE is the total number of distances derived from the PRE–NMR experiment, and NwPRE and NfPRE are the numbers of distances in the working and free data sets, comprising 80 and 20% of the total data, respectively. The percentage of the experimental data that was discarded due to uncertainties of >10% is also shown. The Q values (eq 8) quantify how well the experimental ⟨Rh–1⟩–1 (QRh) and the working (QwPRE) and free (QfPRE) distances were satisfied by the ensemble of structures obtained using PRE-RMD.
