Rmerge = ΣH Σi |Ii(h) − <I(h)>|/ΣHΣi Ii(h), where Ii(h) and <I(h)> are the ith and mean measurement of the intensity of reflection, h. Rwork = ΣH||Fobs (h)| − |Fcalc (h)||/ΣH|Fobs (h)|, where Fobs (h) and Fcalc (h) are the observed and calculated structure factors, respectively. No I/σ cutoff was applied. Rfree is the R value obtained for a test set of reflections consisting of a randomly selected 5% subset of the data set excluded from refinement.

a

Determined with RAMPAGE (Lovell et al., 2003).

b

These numbers correspond to the last resolution shell.
