Data collection, phasing and refinement statistics

†Numbers in parentheses are the high-resolution bin.
aRsym = Σ|I-|Σ, where I is the measured intensity of each reflection, and is the intensity averaged from symmetry equivalents.
bRcryst = Σ|Fo-Fc|/Σ|Fc|, where Fo and Fc are observed and calculated structure factors, respectively.
cRfree was calculated from a test set (8–10%) omitted from the refinement.
drmsd, root mean square deviation.
