Iron–sulfur (Fe–S) clusters are ubiquitous protein cofactors that are required for many important biological processes including oxidative respiration, nitrogen fixation, and photosynthesis. Biosynthetic pathways assemble Fe–S clusters with different iron-to-sulfur stoichiometries and distribute these clusters to appropriate apoproteins.
