Gcn4 and other family members have a DNA recognition motif consisting of a coiled-coil dimerization element, the leucine-zipper, and an adjoining basic region, which mediates DNA binding.  This basic region is largely unstructured in the absence of DNA, addition of DNA containing a Gcn4 binding site induces the transition of this region from unstructured to α-helical.
