  • a Numbers in parentheses refer to the outermost resolution shell.

  • b Rsym = ∑|I − <I>|/∑I, where I is the integrated intensity of a given reflection and <I> is the mean intensity of multiple corresponding symmetry-related reflections.

  • c Rwork = ∑||Fo − |Fc||/∑Fo, where Fo and Fc are the observed and calculated structure factors, respectively. Rfree = Rwork values calculated using 10% random data excluded from the refinement.

  • d The RMSD stereochemistry value represents the deviation from ideal values.

  • e Ramachandran analysis was carried out using Molprobity (81).
