The oxygenase component, which performs the substrate hydroxylation, is an iron-sulfur protein and contains a non-heme iron situated at the active site. The Rieske iron-sulfur cluster and the non-heme Fe2+ catalytic centre are located relatively far away from each other, but the typical head-to-tail trimer arrangement positions the Rieske Fe2-S2 in close proximity to the non-heme Fe2+ of the neighbouring KshA subunit, enabling transport of electrons between KshA subunits 744058 1.14.15.30 [2Fe-2S]-center a Rieske iron-sulfur cluster of the KshA oxygenase component and a plant type iron-sulfur cluster of KshB.
