Rieske dioxygenases contain a Rieske-type [2Fe–2S] cluster and a mononuclear non-heme iron ion in a common 2-His-1-carboxylate facial triad motif.[‌37‌] Crystallographic studies indicate the formation of a side-on (hydro)peroxoiron(III) species at the active site.[‌38‌] One proposed reaction mechanism involving an oxo(hydroxo)iron(V) species is shown in Scheme 8.
