Question

Quizplus · Accepted Answer

When the Catabolite Activator Protein (CAP) binds to its binding site in DNA, it causes a conformational change in the DNA, which results in the bending or distortion of the DNA. This allows CAP to interact with other proteins, such as RNA polymerase, and promote transcription of the gene. CAP does not displace repressors or eliminate the need for a sigma factor on the part of RNA polymerase. While CAP may promote the assembly of other transcription factors at the promoter, its primary role is to enhance the binding and activity of RNA polymerase.
