leucine zipper
a structured motif found in some DNA binding regulatory proteins formed from a region of α-helix containing at least four leucines, each separated by six amino acids from one another; the leucines align along one edge of the α-helix with one leucine at every second turn of the helix such that the leucine of one protein can interdigitate with the leucines of another protein in a zipper manner.
