Figure 3.

Operons for benzoyl-CoA reductases, 2-hydroxyglutaryl-CoA dehydratases, and the region of G. metallireducens genome containing Gmet_0544. Gmet_0544 was previously identified benzoyl-CoA reductase α subunit [22]. Also shown are the regions in the non-aromatics degrading species G. sulfurreducens and P. carbinolicus that contain the Gmet_0544 orthologs. Black – activase subunits, Striped – catalytic subunit, Dotted – catalytic subunit, White – conserved hypothetical, Grey – potential cytochrome.
