<P> The basic leucine zipper ( bZIP ) domain contains an alpha helix with a leucine at every 7th amino acid . If two such helices find one another , the leucines can interact as the teeth in a zipper , allowing dimerization of two proteins . When binding to the DNA , basic amino acid residues bind to the sugar - phosphate backbone while the helices sit in the major grooves . It regulates gene expression . </P>
