Radiation source: E, European Synchrotron Radiation Facility (Grenoble, France); N, National Synchrotron Light Source (Brookhaven, NY).

Values for the highest shell are shown in parentheses.

Completeness calculations treat Friedel-pairs as separate observations.

§

Rsym = ΣΣ I (h)j — 〈I(h)〉/ΣΣ I(h)j where I(h)j is the measured diffraction intensity and the summation includes all observations.

R is the R factor = (Σ|FO| — Σ|FC|)/Σ|FO|.

Rfree is the R factor calculated by using 5% of the data that were excluded from the refinement.

**

Ramachandran core refers to the most favored regions in the ϕ/ψ Ramachandran plot.
