An H-bonding network involving Arg334 orients the oxygen-derived ligand in the FeII-peroxysuccinate complex (A) and vanadyl-bound state of VioC (C). An octahedral base geometry in each state (B, D) leaves a second site open trans to His168. Selected bonding interactions are indicated with distances listed in angstroms (Å) and amino acid side chains and substrate molecules are shown in stick format. Hydrogen bonding interactions and weak coordination bonds are illustrated as black dashed lines. Metal ions and oxygen adducts are shown as space-filling models.
