What is the Function of the Cyclic AMP Binding Proteins

Question

What is the function of the cyclic AMP binding proteins in facultative bacteria?
A) To decrease levels of elongation factors
B) To enhance RNA polymerase activity
C) To facilitate binding of repressor proteins
D) To increase transcription initiation
E) To suppress the Pasteur effect

Accepted Answer

Cyclic AMP binding proteins bind to specific DNA sequences near promoters, which facilitate RNA polymerase binding to the promoters, thus enhancing transcription of genes associated with those promoters.
