Statistics of data collection and refinement for UbiD2 from <i>P. aeruginosa</i>.

Values in parenthesis are for the highest resolution shell. R†merge = ∑hkl ∑i |Ii(hkl)–〈I(hkl)〉|/∑hkl ∑iIi(hkl), where Ii(hkl) is the intensity of an individual reflection and 〈I(hkl)〉 is the average intensity for multiple measurements of that reflection. R‡work = ∑hkl||Fobs|–||Fcalc||/∑hkl |Fobs|, where Fobs and Fcalc are the observed and calculated structure-factor amplitudes, respectively, for 95% of the reflection data used in the refinement. R§free = ∑hkl||Fobs|–||Fcalc||/∑hkl |Fobs| for 5% of the reflection excluded from the refinement. $The twinning operator is shown in parenthesis.
