And once it detaches, that inactivates that adenylate cycling. So once again, as long as that GTP is bound to the alphagy protein, that alphagy protein will remain attached to that adenylate cyclist, which will in turn continue producing those cyclic adenosine monophosphate molecules. So if that G protein is to detach from that cyclase, the GTP must be transformed into GDP. And it turns out that the alphagin has something we call Gtpa's activity, the ability to actually take a water molecule and hydrolyze that GTP into GDP. Now, this hydrolysis doesn't take place immediately after activation of that alpha G protein. And that's because we want to give that alpha G protein the cell wants to give that alphagy protein some time to actually carry out its function before being activated.
