The crystal structure of RO_CH34.A, cartoon representation of RO_CH34 α₃ trimer. The three subunits A, B, and C are colored in green, teal, and blue, respectively. B, cartoon representation of RO_CH34 α protomer (green) with secondary structure elements; the active site entrance is covered with three loops (LI, LII, and LIII), the active site residues are depicted with sticks, and the coordination of the mononuclear iron with residues and glutamate ligand are shown. The Rieske center and the coordinating residues are depicted as sticks, distances are indicated (in Å).
