a Values for the highest resolution shell in parentheses.
b Rsym = ΣΣ I(hkl; j) − 〈I(hkl)〉|/ΣΣ〈I(hkl)〉 with I(hkl; j) being the jth measurement of the intensity of the unique reflection (hkl) and 〈I(hkl)〉 the mean overall symmetry-related measurements (62).
c CC½ correlation coefficient from Ref. 63.
d Rwork = Σ|Fo − Fc|/ΣFo, where Fo and Fc are the observed and calculated structure factor amplitudes. Rfree is claculated similarly to Rwork using a random 5% of the working set of reflections (64).
e MolProbity (40).
