Unified Theory of Bacterial Sialometabolism: How and Why Bacteria Metabolize Host Sialic Acids

Figure 8

The E. coli sialoregulon. In addition to the canonical nan operon (with colored arrows having the same designations as given in Figure 6), other genes regulated by NanR include nanC (pink), nanM (teal), and nanS (magenta), which is homologous to the axe genes shown for streptococci in Figure 6. Another coregulated operon is composed of a putative permease, YjhB (gold) and oxidoreductase, YjhC (grey).
