HEWL molecule. The protein surface is indicated as a ghost surface colored by charge; secondary structure elements are shown as a cartoon. In domain α, helix A (residues 5–16) is indicated by red, helix B (25–37) by orange, helix C (88–101) by purple, helix D (109–116) by yellow, and helix 3₁₀ (120–125) by pink. In domain β, the β1 structure (residues 43–46) is indicated by blue, β2 (51–54) by cyan, β3 (58–60) by ice-blue, and helix 3₁₀ (79–84) by green. The main residues creating the major adsorption site (Lys1, Arg5, Arg125, and Arg128) and the minor one (Arg68) are indicated by light pink and light cyan licorice, respectively.
