Question

Quizplus · Accepted Answer

GlnB is a nitrogen regulatory protein that modulates the activity of glutamine synthetase (GS), an enzyme responsible for ammonium assimilation in bacteria. GS is regulated by the levels of its substrate (glutamine) and product (glutamate). GlnB senses the nitrogen status of the cell and interacts with GS to balance its activity with the cellular demand for nitrogen metabolism. Therefore, GlnB allows cells to balance the rate of GS activity with the rate of glutamine synthesis.
