Catalysis of the transfer of a nitrogenous group from one compound (donor) to another (acceptor). Catalysis of the transfer of an amino group to an acceptor, usually a 2-oxo acid. Catalysis of the reaction: chorismate + glutamine = 4-amino-4-deoxychorismic acid + glutamate. It is composed of two enzymatic activities (which may be present on one or two polypeptides); the first is a glutaminase which yields ammonia from glutamine, releasing glutamate. The ammonia is used by the second activity which catalyzes the amination of chorismate to form 4-amino-4-deoxychorismate.
