Figure 3.

Graph representation of clusters generated from motifs identified in (a) members of the dihydroorotase and (b) β-phosphoglucomutase families, which belong to separate superfamilies, and (c) members of the 2-haloacid dehalogenase (blue) and β-phosphoglucomutase (red) families, which belong to the same superfamily. The families can be subdivided further into additional groups by increasing the edge threshold.
