Figure 4.

The Gal80p/Gal3p interaction occurs through a network of hydrogen bonds. Close-up view of the interface between one monomer of Gal80p (purple) and one monomer of Gal3p. (Light blue) N-terminal; (dark blue) C-terminal. Residues that form either direct or water-mediated contacts are shown in stick representation. Water molecules are shown as red spheres. Direct protein–protein interactions are shown as green dashes, and water-mediated interactions are shown as gray dashes. Ligands are shown in stick representation and are colored as in Figure 2.
