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 … WebCalmodulin, on the other hand, was observed to have no effect on the initial rate of calcium efflux when added either in the absence or in the presence of the catalytic subunit of the cyclic AMP-dependent protein kinase, nor did the addition of 0.5 microM calmodulin result in increased levels of vesicle phosphorylation.
