Reconstructed pathways of carbohydrate utilization in Shewanella pan-genome. Abbreviations for carbohydrates are listed in Table 2. Functional roles implicated in the same catabolic pathway are shown by matching background colors. Novel functional roles predicted in this work are in red boxes. Enzymatic and transport routes are shown by solid and dotted lines, respectively. Transcriptional factors predicted to control sugar utilization pathways are shown in ovals of matching colors. Reactions and enzymes of the central carbohydrate metabolism are shown in magenta. Note that none of the individual Shewanella species contain all (or even most) of the shown pathways.
