An arcane role of DNA in transcription activation.

资源简介：
The mechanism by which the cAMP receptor protein (CRP) activates transcription has been investigated using the lac promoter of Escherichia coli. For transcription activation, an interaction between DNA-bound CRP and RNA polymerase is not sufficient. CRP must bind to a site in the same DNA and close to the promoter. CRP action requires an intact spacer DNA to provide a rigid support in building a CRP-RNA polymerase protein bridge or to allow a conformational change in the DNA to be transmitted to the lac promoter using the protein bridge as a structural support.
