Figure 2.
Figure 2. Interaction Regions I and IIβ-catenin is
represented as in Figure 1, and the arm repeats are marked
“R.” Residues of β-catenin are labeled in bold italics, and
residues of E-cadherin in plain text. Oxygen, nitrogen, and
sulfur are shown as red, blue, and green spheres, respectively.
Individual side chains of β-catenin are shown in purple (H3) or
gray (others). In this and Figures 3, 5, and 6, only those
β-catenin residues that form direct contacts with E-cadherin
are shown. E-cadherin is shown with yellow bonds. Hydrogen bonds
and salt bridges are shown as thin pink lines. (A) Region I.
Nearby region III residues are shown in light yellow. (B) Region
II
