The distribution of the AIR sets used for docking the Zif268-DNA complex is shown as the top and projection views. In the top view, down the DNA helix axis, the AIRs in each zinc finger domain are marked in different colors: finger 1 (red), finger 2 (blue) and finger 3 (green). To better view the AIR distribution in each domain, two lines, which intersect each other in the DNA helical axis that separates each domain, were drawn. In the projection view, each AIR in the domain is represented as a dot. (A) Top view of the first AIR set in the complex, (B) projection view of the first set of AIRs, (C) top view of the second AIR set in the complex, (D) projection view of the second set of AIRs, (E) top view of the third AIR set in the complex, and (F) projection view of the third set of AIRs.
