Regulation of nitrogen metabolism in glutamine auxotrophs of Klebsiella pneumoniae

J M Leonardo et al. J Bacteriol. 1980 Apr.

Abstract

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.
