Statistics of crystallographic analysis for pepQ.

1One crystal was used to collect each of the dataset.2Values in parentheses are for highest-resolution shell.3Rsym = ∑h∑i|Ii,hkl–Ihkl>|/∑hkl∑i |Ii,hkl|, where Ihkl,i is the intensity measured for a given reflection with Miller indices h, k, and l, and Ihkl> is the mean intensity of that reflection.4Rwork = ∑||Fo|−|Fc||/∑|Fo|, where Fo and Fc are the observed and calculated structure-factor amplitudes, respectively.5Rfree was calculated as Rwork using a randomly selected subset (10%) of unique reflections not used for structure refinement.Statistics of crystallographic analysis for pepQ.
