Data collection and refinement statistics for hMtb-BirA (3l2z) and dhMtb-BirA (3l1a).

Values in parentheses are for the highest resolution shell.
†Rmerge = ΣhklΣi |Ihkl −<Ihkl>|/ΣhklΣiIhkl, where Ihkl is the intensity of an individual measurement of the reflection with Miller indices h, k and l and <Ihkl> is the mean intensity of redundant measurements of that reflection.
‡Rwork = Σhkl |Fo(hkl)−Fc(hkl)|/Σhkl |Fo(hkl)|, where Fo and Fc are observed and calculated structure factors, respectively.
§Rfree calculated for a randomly selected subset of reflections (10%) that were omitted during the refinement.
