We use it to actually methylate that product molecule that removes this methyl group, and it forms this molecule we call S adenosyl homocysteine. So once you remove this methyl group, there is no longer positive charge on this sulfur. And so it's slightly more stable than before. The enzyme that catalyzes this process is methyl transferase. That makes sense because this enzyme catalyzes the transfer of this methyl group from Sam on to some target molecule. All right, so once we form this, what happens next?
