  1. *Values in parentheses are for the highest-resolution shell.
  2. Rmerge = ∑|Ii − <I> | /∑ |I| , where Ii is the intensity of an individual reflection, and I is the average intensity of that reflection.
  3. Rwork = ∑||Fo| − |Fc| |/ ∑|Fo| , where Fo and Fc are the observed and calculated structure factors for reflections, respectively.
  4. Rfree was calculated as Rwork using the 5% of reflections that were selected randomly and omitted from refinement.
