FIGURE 3.

Ligand binding profiles of EpaA domains. Pie charts show the glycan types, for which the CFG array binding signals obtained by the different EpaA domains exceeded either 50 or 20%, respectively, of the signal of the best binder and for which terminal disaccharide types are unambiguous. The different glycan types are color-coded according the terminal (primary) carbohydrate moiety and the linkage type to the following (second) carbohydrate unit as indicated on the right side. The areas shown correspond to the logarithm of the fluorescence signal over noise for the best binder as exemplified by the two circles at the lower right. Functional classes are indicated by roman numbers.
