title: Structure of rubredoxin from the bacterium Desulfovibrio desulfuricans.
abstract: The X-ray crystallographic structure of rubredoxin from Desulfovibrio desulfuricans strain 27774 is described. This molecule is 15% smaller than previously studied rubredoxins, lacking a seven-residue loop of chain but containing a histidine and a free-sulfhydryl cysteine. Except for solvent exposure of the single invariant tryptophan, no other major difference occurs in the molecule.
