The mechanism follows the same path, with the general base omitted (as there is no more need for it) and His320 donating its proton to form the ammonia molecule, which is then released from the enzyme.
O mecanismo segue a mesma vía, pero omite a base xeral (xa que non se necesita), e a His320 doa o seu protón para formar a molécula de amoníaco, que despois se libera do encima.
