Statistic of the data collection and structure refinement.

aValues in parentheses correspond to the highest-resolution shell. bRsym = ∑hkl∑i|Ii(hkl)-<I(hkl)>|/∑hkl∑iIi(hkl). cR-factor = ∑hkl||Fo(hkl)|-|Fc(hkl)||/∑hkl|Fo(hkl)|. Rfree is the R-factor calculated for 5% of the data set not included in refinements.
