title: Iron-sulfur proteins: ancient structures, still full of surprises.
abstract: This article is a survey of the properties and functions of Fe-S proteins under the following headings: sulfur and iron; iron-sulfur clusters; evolution of cofactor use; early observations; complex and extended clusters; sulfur exchange and core interconversions; synthesis and biosynthesis of Fe-S clusters; functions of Fe-S clusters: electron transfer, electron delocalization, spin states and magnetism, covalency of sulfur bonds; non-electron transfer functions of Fe-S clusters: substrate binding and catalysis, regulatory and sensing functions.
