Pathways of dissimilatory electron flow, autotrophic CO 2 assimilation and phosphorus metabolism in D. phosphitoxidans . Arrows indicate established metabolic paths; dashed arrows indicate hypothetical electron flows. For the sake of simplicity, oxidation pathways for organic substrates are not shown. Phosphonate dehydrogenase is shown in red; the NAD(P)-dependent epimerase/dehydratase PtdF is shown in purple; high-affinity symporters are shown in grey; hydrogenases are shown in green and the soluble cytochromes are shown in yellow.
