Now, this structure basically goes on and binds until another transmembrane protein, an enzyme found in the membrane known as adenylate cyclase, which is shown here. So the adenylate cyclist basically contains twelve membrane spanning alpha helices found in that membrane. And then we also have two domains found on the intracellular side. And that GTP carrying G alpha protein goes on and binds onto this intracellular domain of the adenoid cyclist. And it stimulates this enzyme to basically carry out its function to transform ATP molecules into the secondary messenger molecules we call cyclic adenosine monophosphates or simply camp. So the dissociated G alpha domain in the GTP state moves and binds to another transmembrane protein, an enzyme, to be specific, called adenylyt cyclist.
