Intermolecular contact surfaces between Shc PTB domain and pY1114 (A), and Shc SH2 domain and pY1173 (B), represented in terms of their molecular surface. The averaged structure (during 1–2-ns period) obtained from 2-ns MD simulation is shown in each panel. pY-peptides are colored orange. Acidic and basic residues are colored red and blue, respectively. Nonpolar and polar residues are colored green and white, respectively.
