Catabolic pathways in S. oneidensis MR-1. Growth substrates and end metabolites are highlighted with boxes, while missing steps are indicated with gray dashed arrows. *Enzymes whose gene expression is regulated by the Arc system (Gao et al. 2008); †enzymes whose gene expression is regulated by the cAMP/CRP system (Charania et al. 2009).
