Table 1. X-ray data collection and refinement statistics.
Numbers in parenthesis are for the resolution shell 1.88–1.78 Å.
Rmerge=(∑hi|Ii(h)-I(h)>|)/(∑hiI(h)), where Ii(h) is the ith measurement of reflection h and I(h)> is the weighted mean of all measurements of h.
 Estimated overall coordinate error from REFMAC5 based on maximum likelihood.
