title: In vitro selection by using mutated GCN4-bZIP peptides for analysis of peptide-DNA interactions.
abstract: In vitro selection has been used as a method to determine the optimal binding site for DNA-binding proteins. We report here in vitro selection of dsDNA sequences that bind to mutated-GCN4-bZIP peptides. The GCN4-bZIP peptide mutated from alanine to histidine on a position-14 that contacts with DNA bound to different sequence from a binding site of wild type peptide.
