The (2Fo − Fc) OMIT electron-density map (magenta mesh) contoured at 1.4 σ is superimposed on the refined model. a AibH2 subunit bound to two Fe ions. Fe ions are shown as orange spheres and coordinated by six AibH2 residues (shown as the green sticks), O atom (cyan sphere), and EDO. The (Fo − Fc) OMIT electron-density map (blue mesh) contoured at 3.0 σ is also superimposed. b AibH1 bound to a Zn ion. Zn ion is shown as a gray sphere and coordinated by five AibH1 residues (shown as the green sticks). Black dashes indicate metal coordination and selected hydrogen bonds.
