RMSD, root mean square deviation of Cα-carbon atoms of the main chain. Rwork, ∑ hkl II Fobs (hkl)I -IFcalc II/∑ hkl I Fobs (hkl)I for reflections in the working dataset. Rfree, cross validation R-factor for 5% of reflections against which the model was not refined. The highest resolution shell is 1.90–1.95 Å (in parentheses).
