Proteins containing iron-sulfur complexes, displaying electron-carrier activity but no classical enzyme function. F. are found in green plants, algae, anaerobic bacteria, and in mitochondria from the adrenal cortex and heart muscle. They are involved in several oxidation-reduction reactions in living organisms ( e.g., nitrogen fixation).
