Iron–sulfur cluster biosynthesis in bacteria: Mechanisms

WebIron-sulfur (Fe–S) clusters are essential cofactors most commonly known for their role mediating electron transfer within the mitochondrial respiratory chain. The Fe–S cluster pathways that function within the respiratory complexes are highly conserved between bacteria and the mitochondria of eukaryotic cells. WebIron-oxidizing bacteria typically live in acidic, aerobic environments rich in both reduced-iron and -sulfur compounds; they grow poorly at pH values greater than 4. Among other things, …
