Figure 2

(A) Stereoview of the superposition of the ensemble of 17 accepted structures of NiARD from the current refinement. Orientation is approximately the same as in Figure 1. RMSD for backbone heavy atoms is 0.65 Å. RMSD for all heavy atoms is 1.28 Å. Figure generated using MOLMOL (Koradi et al., 1996). (B) Heavy atom positions from a representative member of the ensemble in A, shown in approximately the same orientation as in A. Paramagnetically affected residues are shown in bold. Color key: red, Trp 162-Phe 166; purple, Asn 94-Val 103; yellow, Val 134-Asp 143. Position of Ni2+ indicated by a green sphere. (C) Metal binding site of NiARD based on modeling as described in the text. Position of Ni2+ indicated by a green sphere. View is from the opening to the active site (over strand N, with helix G to the upper left).
