So the oxidative diamondation step. So once we transfer that amino group from the target amino acid onto the alpha key to glutary to form the glutamate, what is the fate of that glutamate? Well, what we want to do is we want to deaminate the glutamate. And this happens in a two step process. So we have a dehydrogenation, and then we have this hydrolysis reaction. So we take the glutamate, and we basically want to remove this h here and this h here.
