The correct transcription of the hut (histidine utilization) operon DNA of Salmonella typhimurium requires activation either by 3':5'-cyclic adenosine monophosphate and catabolite-activating protein or by nonadenylylated glutamine synthetase (EC 6.3.1.2.). Thus, glutamine synthetase plays a regulatory role distinct from its enzymatic function.
鼠伤寒沙门氏菌的组氨酸利用(hut)操纵子DNA的正确转录需要3':5'-环磷酸腺苷和分解代谢物激活蛋白或未腺苷酸化的谷氨酰胺合成酶(EC 6.3.1.2)的激活。因此,谷氨酰胺合成酶发挥着与其酶功能不同的调节作用。
