DNA-binding proteins frequently utilize short
-helices as their critical DNA recognition elements. In this research, we have employed the structure-based design to construct a small domain that could target the specific DNA sequences recognized by the yeast transcriptional activator GCN4. The new DNA binding motif recognizes specific DNA sequences as a dimer with high affinity and specificity under the physiological conditions.
