a
Rcryst = Σ∥Fo−Fc∥/ΣFo, where Fo and Fc are the observed and calculated structure factor amplitudes used in refinement. Rfree is calculated as Rcryst, but using the “test” set of structure factor amplitudes that were withheld from refinement (4.9%).
b
Correlation coefficient (CC) is agreement between the model and 2mFo − DFc density map.
c
Calculated using PROCHECK (33).
