Refinement | Method to determine structure: AB INITIO / Resolution: 1.2→10 Å / Num. parameters: 1689 / Num. restraintsaints: 2071 / Cross valid method: FREE R / σ(F): 0 / Stereochemistry target values: ENGH AND HUBER Details: This structure was obtained by refining entry 1FY2 with SHELX and anisotropic B-factors using the same data. The authors recommend 1FY2 (isotropic B-factor refinement)as the better of the two structures.
