cAMP Receptor Protein from <i>Escherichia coli</i> as a Model of Signal Transduction in Proteins – A Review

Abstract: In Escherichia coli, cyclic AMP receptor protein (CRP) is known to regulate the transcription of about 100 genes. The signal to activate CRP is the binding of cyclic AMP. It has been suggested that binding of cAMP to CRP leads to a long-distance signal transduction from the N-terminal cAMP-binding domain to the C-terminal domain of the protein, which is responsible for interaction with specific sequences of DNA. The signal transduction plays a crucial role in the activation of the protein. The most sophisticat… Show more

“…One well-characterized regulator of the genes for carbon source utilization is CRP (cyclic AMP [cAMP] receptor protein) (sometimes called catabolite activator protein [CAP]), which is converted into the functional form after binding cAMP that is synthesized in the absence of glucose (10,22). Besides CRP, another transcription factor, Cra (catabolite repressor activator), has been indicated to play a role in the global regulation of the genes for carbon metabolism (16,46).…”

“…cAMP is produced by adenylate cyclase (CyaA) in low-glucose environments, leading to activation of CRP (13). Glucose inhibits E. coli biofilm formation, and ⌬cyaA and ⌬crp laboratory strains have a decreased propensity for biofilm formation, suggesting that cAMP and CRP are important for regulating biofilm development (14,15).…”

“…1B) (20)(21)(22); and it is specifically induced when phenylethylamine (PEA) is provided as a carbon source (20). The fact that Crp regulates this pathway (23,24) indicates that it serves a catabolic role rather than exclusively one of detoxification. Indeed, it has been shown that the pathway can enable E. coli to grow using PEA as the sole carbon source (20).…”
