METHODS Overproduction and purification of proteins and assays of their activities. Proteins
were overexpressed and purified as described previously (Porter et al. 1993; Flashner et al …

The Klebsiella pneumoniae nitrogen regulatory protein NTRC is a response regulator which
activates transcription in response to nitrogen limitation, and is a member of the family of σN …

The bacterial enhancer-binding protein NtrC is a well-studied response regulator in a two-
component regulatory system. The amino (N)-terminal receiver domain of NtrC modulates …

Eukaryotic enhancer-binding proteins are often modular in design in that they are composed
of physically separable domains that can function independently of one another (18, 46, 55) …

The bacterial enhancer-binding protein NtrC activates transcription when phosphorylated on
aspartate 54 in its amino (N)-terminal regulatory domain or when altered by constitutively …

The prokaryotic activator protein NTRC binds to enhancer‐like elements and activates
transcription in response to nitrogen limitation by catalysing open complex formation by …

NTRC is a prokaryotic enhancer-binding protein that activates transcription by sigma 54-
holoenzyme. NTRC has an ATPase activity that is required for transcriptional activation …

When phosphorylated, the dimeric form of nitrogen regulatory protein C (NtrC) of Salmonella
typhimurium forms a larger oligomer (s) that can hydrolyze ATP and hence activate …

The NTRC protein of enteric bacteria is an enhancerbinding protein that activates
transcription in response to limitation of combined nitrogen. NTRC activates transcription by …

The bacterial enhancer-binding protein nitrogen regulatory protein C (NtrC) activates
transcription by σ54-containing RNA polymerase in a reaction that depends on ATP …
