A Rieske iron-sulfur cluster is a type of [iron-sulfur cluster]() that plays a crucial role in various biological processes, particularly in [electron transport]() and [oxidation-reduction reactions](). It is characterized by a unique 2Fe-2S core where one of the iron atoms is coordinated by two histidine residues, distinguishing it from other iron-sulfur clusters like [2Fe-2S]() and [4Fe-4S]() clusters.
