Does cyclic amp binds to calmodulin
WebOnce this happens, our cyclic AMP here is what we call a second messenger. Our signal or epinephrine goes through this entire process and the signal is transformed into another signal. The cyclic AMP which is now inside our cell. This cyclic AMP will now tell our cell to do other things. For example is that it will increase our heart rate. WebCyclic AMP is also found in the lac operon, where it regulates the catabolite activator protein (CAP). RNA polymerase, an enzyme found in the lac operon that aids in transcription, does not bind as well to the promoter as expected, so it needs CAP to assist by binding to a region of DNA next to the promoter. The CAP bound next to the promoter …
