FIGURE 6.

Cartoon depicting putative metabolism of GAL08 based on SAG analysis. Predicted metabolic components include an oxidative phosphorylation pathway, an incomplete denitrification pathway (absence of nirKS), acetate fermentation, fatty acid degradation, a small number of ABC transporters (shown in orange on the left of the figure), a PTS system for mannose, several major facilitator superfamily transporters, Sec-SRP plus TolC and Type II secretion systems, a TonB-dependent outer membrane transport system possibly acting in siderophore transport, and potential fermentation pathways. The symbol “?” and dashed lines both indicate a speculative metabolic component or product. A list of accession numbers for the genes shown is provided in Supplementary Table 4. A list of amino acid auxotrophies is shown in Supplementary Table 6.
