Iron-sulfur proteins are a class of metalloproteins that contain iron and sulfur in their structure, often forming clusters known as iron-sulfur clusters. These clusters typically consist of iron and inorganic sulfide ions (S²⁻), and may also include additional ligands such as cysteine residues from the protein.
