Binding of the WRPW and eh1 peptide motifs to the WD domain. Model showing the structure of the WD domain (rainbow ribbons) bound to the WRPW and eh1 (FSIDNIL) peptide motifs (light-gray sticks). Although these peptide motifs fold to form quite different structures, they bind overlapping sites on the same surface across the central pore of the β-propeller. For a more detailed structural analysis see [15].
