  1. aValues in parentheses refer to statistics in the highest-resolution shell.
  2. bRmerge = Σ|Iobs − <I>|/ΣIobs.
  3. cR factor  = Σ|FobsFcalc|/ΣFobs, where Fobs and Fcalc are the observed and calculated structure factor amplitudes, respectively.
  4. dRfree was computed using 5% of the data assigned randomly.
  5. er.m.s.d., root mean square deviation.
  6. fRoot mean square deviation.
  7. gEstimated standard uncertainties based on maximum likelihood.
