Figure 4. Predicted central carbon metabolism of S. thermosulfidooxidans (see also Table S4 in File S1 for further details on respective EC numbers and annotation classification).

Enzymatic reactions for which candidate genes can be identified in the genome of S. thermosulfidooxidans are highlighted by solid arrows. The reactions associated with other metabolic pathways are shown with pink arrows. The transmembrane transports of small organic compounds that may directly enter central carbon metabolism are also presented.
