Metal ion-binding site. (A) Mn2+-binding site of bfNrn. Electron density (magenta) of the Mn2+ ions derived from an anomalous difference Fourier map (λ = 1.892000 Å) is superimposed on the model. The positions of the Mn2+ ions are shown as a magenta sphere. Water molecules are shown as cyan spheres. The dashed lines show the coordination with the metal ion (distances given in Å). (B) Mg2+-binding site of shNrn (PDB ID: 3DEV). The position of the Mg2+ ion is shown by a green sphere. (C) Mn2+-binding site of ttRecJ ttRecJ (PDB ID: 2ZXP). The motif names are indicated in parentheses.
