Crystal structure of GCN4 bound to DNA (pdb:1YSA) (62). The eight predicted residues for the basic leucine zipper family are shown in VDW representation. The top ranked residue is colored red and the eighth is colored blue, with the colors shifted stepwise from red to blue for residues two through seven. The protein is shown in ribbon representation (colored black) and the DNA in lines representation (black). Figure made using VMD (63).
