Rubredoxin from Clostridium pasteurianum. Structures of G10A, G43A and G10VG43A mutant proteins. Mutation of conserved glycine 10 to valine causes the 9-10 peptide link to invert.

Abstract excerpt

The four cysteine ligands which coordinate the Fe atom in the electron-transfer protein rubredoxin lie on loops of the polypeptide which form approximate local twofold symmetry. The cysteine ligands in the protein from Clostridium pasteurianum lie at positions 6, 9, 39 and 42. Two glycine residues adjacent to the cysteine ligands at positions 10 and 43 are conserved in all rubredoxins, consistent with the...
