cAMP receptor protein (in short CRP, also known as catabolite gene activator protein (in short CAP)) is a regulatory protein in bacteria. This protein binds cAMP, which causes a conformational change that allows the protein to bind to tightly to a specific DNA sequence in the promoters of the genes it controls.[1] The genes regulated by this protein are mostly involved in energy metabolism, such as galactose, citrate, or the PEP group translocation system.[2][3]
