| leucine zippers | Domains in DNA-binding proteins that contain amino acid sequences that show periodic arrays of leucine residues. These residues exist in an alpha-helical conformation, with the leucine side chains extending from one alpha helix interdigitating with those displayed from a similar alpha helix of a second polypeptide, facilitating dimerization.
