我们检查了肺炎克雷伯菌的四类（glnA、glnB、glnF 和 glnG）Gln 营养缺陷型细菌的氮代谢调节。这些研究表明，谷氨酰胺合成酶并不直接介导该生物体对 NH4+ 的生理反应。我们提供的证据表明，NH4+ 对涉及氮代谢的基因表达的影响涉及 glnF 和 glnG 基因的产物。
We examined the regulation of nitrogen metabolism in four classes (glnA, glnB, glnF, and glnG) of Gln- auxotrophs of Klebsiella pneumoniae. These studies indicate that glutamine synthetase does not directly mediate the physiological response to NH4+ in this organism. We present evidence suggesting that the effect of NH4+ on the expression of genes involved in nitrogen metabolism involves the products of the glnF and glnG genes.
