Pathways of oxidation of aromatic compounds in G. metallireducens inferred from the whole-genome gene content. Enzymes of the benzoyl-CoA pathway indicated: benzoate CoA ligase (BclA), cyclohexa-1,5-diene-1-carbonyl-CoA hydratase (Dch), 6-hydroxycylohex-1-en-1-carbonyl-CoA dehydrogenase (Had), 6-oxocyclohex-1-ene-1-carbonyl-CoA hydratase (Oah). Red coloring indicates that the gene was induced during growth by benzoate oxidation. The "?" indicates that no orthologs to known benzoyl-CoA reductases found. Figure adapted from .
