摘要

The solution structure of the three-heme electron transfer protein cytochrome c7 from Desulfuromonas acetoxidans is reported. The determination of the structure is obtained through NMR spectroscopy on the fully oxidized, paramagnetic form. The richness of structural motifs and the presence of three prosthetic groups in a protein of 68 residues is discussed in comparison with the four-heme cytochromes c_3 already characterized through x-ray crystallography.
