Fo-Fc electron density maps for viperin. The [4Fe-4S] cluster (A), SAH (B), l-Met (C), and 5′-dAdo (D) are shown. The maps were calculated after removing the cluster or ligands from the refined structure, and are contoured at 2.5-fold the rms value of the map (green) or 25-fold the rms value of the map (magenta).
