Superposition of mean backbone atom positions of the NiARD structure from 1M4O onto average structure from the current refinement. Superposition was performed for backbone atoms in the β-sandwich and helices C and G (residues 2-36 and 95-154 inclusive) to emphasize changes in positions of helices E and E′ (blue neon). RMSD for this superposition is 1.84 Å. If helix P is included in the fit (residues 170–175), RMSD is 1.93 Å. Modeled residues Trp 162- Phe 166 are shown in red neon, with the large shift in position due to the incorporation of hydrogen bonds between residues Ile 163 and Thr 97 based on the 1VR3 crystal structure (see text). Residues 155–160 are shown in green neon. Figure generated using MOLMOL.
