We constructed monocopy lac operon control regions in which the operators O1-lac and O3-lac were replaced by NarL and NarP binding sites from the nirB or napF operon control regions. The results support the hypothesis that DNA-bound dimers of phospho-NarL can participate in higher-order cooperative interactions.
