additional information | leaves of transgenic poplar with ectopic expression of the pine cytosolic glutamine synthetase, GS1a, EC 6.3.1.2, produce significantly more glutamine and significantly enhanced ASA alpha-subunit (ASA1) transcript and protein, approximately 130% and 120% higher than in the untransformed controls, respectively. L-Glutamate, tryptophan, and 4-aminobutanoate are also significantly enhanced in the GS1a transgenic poplars | Populus tremula x Populus alba |
additional information | tobacco leaves fed with 30 mM glutamine and 2 mM chorismate produce significantly enhanced ASA alpha-subunit (ASA1) transcript and protein, approximately 175% and 90% higher than in the untransformed controls, respectively | Nicotiana tabacum |

metabolism | the enzyme catalyzes the initial step in the pathway for both tryptophan-dependent and tryptophan-independent pathways in the biosynthesis of indole-3-acetic acid, the transfer of the alpha-amino group of glutamine to chorismate producing anthranilate | Nicotiana tabacum |
