Active contribution of two domains to cooperative DNA binding of the enhancer-binding protein nitrogen regulator I (NtrC) of Escherichia coli: stimulation by phosphorylation and the binding of ATP.

Chen, P, Reitzer, L J

Activation by the prokaryotic activator nitrogen regulator I (NRI, or NtrC) of Escherichia coli requires an interaction between two NRI dimers. ATP-dependent phosphorylation stimulates this...

Effects of insertions and deletions in glnG (ntrC) of Escherichia coli on nitrogen regulator I-dependent DNA binding and transcriptional activation.

Shiau, S P, Chen, P, Reitzer, L J

Phosphorylated nitrogen regulator I (NRI, also called NTRC), encoded by glnG (ntrC), stimulates transcription in Escherichia coli and other enteric bacteria from sites analogous to eukaryotic...

Alterations of highly conserved residues in the regulatory domain of nitrogen regulator I (NtrC) of Escherichia coli.

Moore, J B, Shiau, S P, Reitzer, L J

Transcription of many nitrogen-regulated (Ntr) genes requires the phosphorylated form of nitrogen regulator I (NRI, or NtrC), which binds to sites that are analogous to eukaryotic enhancers. A highly...

Role of nitrogen regulator I (NtrC), the transcriptional activator of glnA in enteric bacteria, in reducing expression of glnA during nitrogen-limited growth.

Shiau, S P, Schneider, B L, Gu, W, Reitzer, L J

During nitrogen-limited growth, transcription of glnA, which codes for glutamine synthetase, requires sigma 54-RNA polymerase and the phosphorylated from the nitrogen regulator I (NRI; also called...

Role of multiple environmental stimuli in control of transcription from a nitrogen-regulated promoter in Escherichia coli with weak or no activator-binding sites.

Schneider, B L, Shiau, S P, Reitzer, L J

Nitrogen regulator I (NRI [or NtrC])-phosphate stimulates transcription from the glnAp2 promoter of the glnALG operon in enteric bacteria. Unlike most activators, NRI-phosphate can stimulate...

Activation of glnA transcription by nitrogen regulator I (NRI)-phosphate in Escherichia coli: evidence for a long-range physical interaction between NRI-phosphate and RNA polymerase.

Reitzer, L J, Movsas, B, Magasanik, B

Growth of cells of Escherichia coli in nitrogen-limited medium induces the formation of glutamine synthetase, product of the glnA gene, and of other proteins that facilitate the assimilation of...

Mutations that create new promoters suppress the sigma 54 dependence of glnA transcription in Escherichia coli.

Reitzer, L J, Bueno, R, Cheng, W D, Abrams, S A, Rothstein, D M, Hunt, T P, ...

Escherichia coli rpoN mutants lack sigma 54 and are therefore unable to initiate the transcription of glnA at glnAp2, which is required for the production of a high intracellular concentration of...

Identification and regulation of the glnL operator-promoter of the complex glnALG operon of Escherichia coli.

Ueno-Nishio, S, Mango, S, Reitzer, L J, Magasanik, B

We sequenced the 274-nucleotide intercistronic glnA-glnL region of Escherichia coli to localize regulatory regions postulated from genetic evidence. The transcriptional start of glnLp, identified by...

Expression of glnA in Escherichia coli is regulated at tandem promoters.

Reitzer, L J, Magasanik, B

We have determined that the glnA gene of the complex glnALG operon of Escherichia coli is transcribed from tandem promoters. Expression from the upstream promoter, glnAp1, requires the catabolite...
