Abstract	We report the first detailed quantitative study of divergent promoters dependent on the Escherichia coli cAMP receptor protein (CRP), a factor known to activate transcription initiation at target promoters by making direct interactions with the RNA polymerase holoenzyme. In this work, we show that CRP bound at a single target site is able to activate transcription at two divergently organized promoters. Experiments using promoter probe plasmids, designed to study divergent promoters in vivo and in vitro, show that the divergent promoters function independently. Further in vitro experiments show that two holo RNA polymerase molecules cannot be accommodated simultaneously at the divergent promoters.
