WebAdenylyl cyclases (ACs) are vital in both eukaryotes and prokaryotes, where they generate the cyclic AMP required for a multitude of cellular functions. Although mammalian and bacterial ACs differ structurally, they appear to have converged on a common catalytic mechanism shared by RNA and DNA polymerases. WebJul 1, 1983 · Agents that increase cellular cyclic adenosine monophosphate (cyclic AMP) levels exert several effects on cardiac function. These include increases in heart rate and both the force of contraction and rate of relaxation. The latter effects, which might appear to be contradictory, actually represent essential components of the response needed to ...
