Probing the iron environment in desulforedoxin. EXAFS of oxidized and reduced states, Stalhandske, CMV, Dong J., Tavares P., Liu M. Y., Legall J., Moura J. J. G., Moura I., Park J. B., Adams M. W. W., and Scott R. A. , INORGANICA CHIMICA ACTA, Volume {273}, Number {1-2}, p.{409-411}, (1998) Abstract

Fe XAS data were collected on the oxidized and reduced forms of desulforedoxin from Desulfovibrio gigas, the oxidized form of rubredoxin from Clostridium pasteurianum, and the reduced form of rubredoxin from Pyrococcus furiosus. Analysis of these data is consistent with tetrahedral FeS(4) coordination in both oxidation states, and an expansion of the Fe-S distances from 2.27 to 2.33 Angstrom upon reduction.
