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? Well, in the next step, we basically want to remove that adenosine group. And so what happens is this entire group is actually removed, and the enzyme that catalyzes this is adenosyl homocysteinease. And so the product molecule that we form is the homocysteine.
