a Rsym = Σ|Ii − <I>|/ΣIi, where Ii is the intensity of ith observation and <I> is the mean intensity of the reflection.
b Values in parentheses are for reflections in the highest resolution shell.
c Rcryst = Σ|Fobs − Fcalc|/ΣFobs where Fobs and Fcalc are the observed and calculated structure factor amplitudes, respectively. Rcryst and Rfree were calculated using the working and test set, respectively.
