COMMENT     In some organisms, this enzyme is part of a multifunctional
            protein together with one or more other components of the system
            for biosynthesis of tryptophan (EC 4.1.1.48, 4.1.3.27, 4.2.1.20,
            5.3.1.24).
PATHWAY     PATH: MAP00400  Phenylalanine, tyrosine and tryptophan biosynthesis
