FIG 1

The ecological distribution of PULs in nature. PULs are found in a variety of microbial communities, highlighting the global role of this polysaccharide utilization strategy. Each semitransparent box contains a representative bacterial PUL from a distinct microbial ecosystem, as well as the schematic structure of the target glycan. Clockwise from the top left are the arabinan PUL from an unidentified bacterium from the gut of Pseudocanthotermes militaris (93), the xylan PUL from Prevotella bryantii (97), the laminarin PUL from Gramella forsetii (101), the xyloglucan PUL from Bacteroides ovatus (78), the chitin PUL from Flavobacterium johnsoniae (112), and the xyloglucan PUL from Cellvibrio japonicus (126). Genes are colored according to protein function as follows: blue, endo-GH; cyan, exo-GH; orange, SusD-homologous SGBP; yellow, other SGBP; purple, TBDT; pink, (hybrid) two-component sensor (HTCS/TCS); gray, unknown or other function (est, esterase; transp, transporter; deam, deaminase). Monosaccharides are represented by Consortium for Functional Glycomics symbols (154).
