Figure 6

The most abundant monosaccharides in bacteria. Circle areas reflect relative abundances of the 30 most common monosaccharide residues (A) or basic entities (B) for the carbohydrates found in the BCSDB for each of the bacterial taxonomy groups of Set 2. Within each group the abundances are normalized to the total number of residues per group. The color code (see legend at bottom) is the same as in Figs. 2–4; for comparison, the open circles represent data for mammals. The residues are sorted from top to bottom in order of decreasing total abundance in bacteria (order differs from Fig. 5). The residue Kdo (without anomeric configuration) results from analytical artifacts and is highlighted in gray. For the basic entities defined in B, no distinction is made between anomeric configurations and ring types.
