The glutamine synthetase from Klebsiella aerogenes is similar to that from Escherichia coli in several respects, but it is necessary to use special methods to harvest growing cells to prevent changes in the adenylylation state of GS from occurring during harvesting.

- 1 September 1991
The regulatory regions for 119 Escherichia coli promoters have been analyzed, and the locations of the regulatory sites have been cataloged. The following observations emerge. (i) More than 95% of…
Role of the GATA factors Gln3p and Nil1p of Saccharomyces cerevisiae in the expression of nitrogen-regulated genes.

The NIL1 gene is isolated by virtue of the homology of its zinc-finger domain to that of the previously identified activator, the product of GLN3, and the results show that the nature of GATAAG sequence that serve as the upstream activation sequence elements for these genes determines their abilities to respond to Gln3p and Nil1p.
Initiation of transcription at the bacterial glnAp2 promoter by purified E. coli components is facilitated by enhancers

Transcriptional and posttranslational regulation of the general amino acid permease of Saccharomyces cerevisiae
- M. Stanbrough, B. Magasanik
- BiologyJournal of Bacteriology
- 1 January 1995
Results suggest that inactivation of the permease results from its dephosphorylation, which is followed by slower disappearance of the protein.
Covalent modification of the glnG product, NRI, by the glnL product, NRII, regulates the transcription of the glnALG operon in Escherichia coli.

- 1 August 1986
It is proposed that NRI-phosphate activates transcription from nitrogen-regulated promoters and that the role of NRII is control of the formation and breakdown of N RI-ph phosphate in response to cellular signals of nitrogen availability.
Role of NAD-linked glutamate dehydrogenase in nitrogen metabolism in Saccharomyces cerevisiae

- 1 September 1990
We cloned GDH2, the gene that encodes the NAD-linked glutamate dehydrogenase in the yeast Saccharomyces cerevisiae, by purifying the enzyme, making polyclonal antibodies to it, and using the…
Regulation of nitrogen assimilation in Saccharomyces cerevisiae: roles of the URE2 and GLN3 genes
- W. Courchesne, B. Magasanik
- Biology, ChemistryJournal of Bacteriology
- 1 February 1988
It is proposed that the URE2-GLN3 system regulates enzyme synthesis, in response to glutamine and glutamate, to adjust the intracellular concentration of ammonia so as to maintain glutamine at the level required for optimal growth.
