Figure 3. Ribbon drawings of the seven structural domains of Desulfovibrio africanus PFOR. In the included topology diagrams, −helices are represented by circles and −strands by triangles. A common folding motif in the core domains I, II and VI is indicated by the dots in their topology diagrams. For clarity, domains and topology diagrams are not represented in the same orientation.
