LITERATURE
three-dimensional structure of the fusion protein with electron-transferring protein TsdB, to 2.75 A resolution. In the oxidized state, the tetraheme cytochrome c contains three hemes with axial His/Met ligation, whereas heme 3 exhibits the His/Cys coordination typical for TsdA active sites. Thiosulfate is covalently bound to Cys330 on heme 3
