Figure 4

The gene cluster (GSU2937 through GSU2930) encoding the putative inner-membrane cytochrome bc complex that is conserved in all six Geobacter species. Genes encoding c-type cytochromes are shown in yellow, the Fe-S cluster protein encoding gene is shown in purple, and the cytochrome b gene is shown in green. All of these protein are orthologs across all of the Geobacter genomes (Table 5). The c-type cytochromes contain 2, 10, 12, and 5 heme-binding motifs each, respectively (see Additional file 9).
