The iron-sulfur environment in rubredoxin
Biophys J.
1977 Sep.
Abstract
The atomic environment around the iron site in the nonheme iron sulfur protein rubredoxin was studied by the extended X-ray absorption fine structure (EXAFS) technique. Within experimental error, the Fe-S bonds in oxidized Clostridium pasteurianum rubredoxin are the same as in the analogue anion [Fe(S2-o-xyl)2]-synthesized by Holm. The average Fe-S bond length is 2.267 +/- 0.003A and the root mean square deviation about this average due to structural disorder is 0.032 + 0.013 - 0.032.
