Rubredoxins are a class of low-molecular-weight iron-containing proteins found in sulfur-metabolizing bacteria and archaea. Sometimes rubredoxins are classified as iron-sulfur proteins; however in contrast to iron-sulfur proteins rubredoxins do not contain inorganic sulfide. Like cytochromes ferredoxins and Rieske proteins rubredoxins participate in electron transfer in biological systems.
