Co-regulation by bent DNA. Functional substitutions of the integration host factor site at sigma 54-dependent promoter Pu of the upper-TOL operon by intrinsically curved sequences.

The Journal of biological chemistry - 9 Sept 1994

Pérez-Martín J, Timmis K N, de Lorenzo V

Abstract excerpt

The role of integration host factor (IHF) in the regulation of the sigma 54-dependent promoter Pu of the TOL plasmid of Pseudomonas putida has been examined. We have selected in vivo insertions of intrinsically curved DNA that restore the responsiveness of an IHF-binding site deletion variant of...
