Abstract
The glnL product is not necessary for the control of expression of glnA and other nitrogen-regulated genes, but it presumably communicates reduntant information on the availability of ammonia from an ammonia-sensitive system consisting of the products of glnB and glnD to the regulatory products of glnF and glnG.
摘要
谷氨酰胺合成酶基因L产物对于谷氨酰胺合成酶基因A及其他氮调节基因表达的控制并非必需，但它可能将来自由谷氨酰胺合成酶基因B和谷氨酰胺合成酶基因D产物组成的氨敏感系统的关于氨可用性的冗余信息传递给谷氨酰胺合成酶基因F和谷氨酰胺合成酶基因G的调节产物。
