(a) & (b): Visualization of the helix-helix interaction for helices 2 and 3 (Left-hand side), as well as 2 and 5 (Right-hand side) of Vif (PDB ID: 1VZF). Part (A) shows hydrogen bonding within the two helices with geometric characteristics. Part (B) focuses specifically on the helix-helix interface; the surface depicted between the helices is formed by the shared polyhedra faces derived from the Voronoi packaging calculation
