Abstract
Fe XAS data were collected on the oxidized and reduced forms of desulf oredoxin from Desulfovibrio gigas, the oxidized form of rubredoxin fro m Clostridium pasteurianum, and the reduced form of rubredoxin from Py rococcus furiosus. Analysis of these data is consistent with tetrahedr al FeS4 coordination in both oxidation states, and an expansion of the Fe-S distances from 2.27 to 2.33 Angstrom upon reduction.
