Conclusion
Both the in vitro and in vivo data reported here strongly support the hypothesis that Hha and H-NS interact with DNA to generate a nucleoprotein complex that influences gene expression. The Hha-H-NS complex seems to be mainly responsible for the thermoosmotic modulation of the expression of the hly operon of plasmid pHly152. Binding sites for Hha and H-NS along the regulatory region of the hly operon, as well as the topological changes mediated by the interaction of both proteins with DNA, are currently being investigated.
