== Function ==
[https://www.uniprot.org/uniprot/CRP_ECOLI CRP_ECOLI] This protein complexes with cyclic AMP and binds to specific DNA sites near the promoter to regulate the transcription of several catabolite-sensitive operons. The protein induces a severe bend in the DNA. Acts as a negative regulator of its own synthesis as well as for adenylate cyclase (cyaA), which generates cAMP.<ref>PMID:2982847</ref>
