¹ Numbers in parentheses refer to the highest resolution shell.
² R = Σ||Fo-|Fc||/Σ|Fo|, where Fo and Fc are the observed and calculated structure factors, respectively. Rfree = analogous to R-factor except the summation is over 5% of reflections excluded for refinement.
³ Categories were defined using MolProbity [55].
