NtrC-dependent control of exopolysaccharide synthesis and motility in Burkholderia cenocepacia H111. [PDF]

PLoS ONE, 2017
Burkholderia cenocepacia is a versatile opportunistic pathogen that survives in a wide variety of environments, which can be limited in nutrients such as nitrogen.

Transcriptomic analysis reveals the participation of NTRC in iron homeostasis in Arabidopsis. [PDF]

Physiol Plant
Abstract NADPH‐dependent thioredoxin reductase C (NTRC) plays a central role in redox regulation of chloroplast photosynthetic metabolism. Accordingly, Arabidopsis ( Arabidopsis thaliana ) NTRC‐null mutants show defective photosynthetic performance and growth inhibition ...

ntrC Contributes to Nitrogen Utilization, Stress Tolerance, and Virulence in Acidovorax citrulli

Microorganisms, 2023
Bacterial fruit blotch (BFB), caused by Acidovorax citrulli, severely damages watermelon, melon, and other cucurbit crops worldwide. Nitrogen, one of the most important limiting elements in the environment, is necessary for the growth and reproduction of

NtrC-Dependent Regulatory Network for Nitrogen Assimilation in Pseudomonas putida [PDF]

Journal of Bacteriology, 2009
ABSTRACT Pseudomonas putida KT2440 is a model strain for studying bacterial biodegradation processes. However, very little is known about nitrogen regulation in this strain. Here, we show that the nitrogen regulatory NtrC proteins from P.

NTRC and TRX-f Coordinately Affect the Levels of Enzymes of Chlorophyll Biosynthesis in a Light-Dependent Manner

Cells, 2023
Redox regulation of plastid gene expression and different metabolic pathways promotes many activities of redox-sensitive proteins. We address the question of how the plastid redox state and the contributing reducing enzymes control the enzymes of ...

Physical evidence for a phosphorylation-dependent conformational change in the enhancer-binding protein NtrC [PDF]

Proceedings of the National Academy of Sciences, 1999
The bacterial enhancer-binding protein nitrogen regulatory protein C (NtrC) activates transcription by σ 54 -containing RNA polymerase in a reaction that depends on ATP hydrolysis. Phosphorylation of an aspartate residue in the N-terminal receiver domain of NtrC induces oligomerization of the protein and activates ...

A new type of NtrC transcriptional activator [PDF]

Journal of Bacteriology, 1994
The enteric NtrC (NRI) protein has been the paradigm for a class of bacterial enhancer-binding proteins (EBPs) that activate transcription of RNA polymerase containing the sigma 54 factor. Activators in the NtrC class are characterized by essentially three properties: (i) they bind to sites distant from the promoters that they activate (> 100 bp ...

NADPH-dependent thioredoxin reductase C plays a role in nonhost disease resistance against Pseudomonas syringae pathogens by regulating chloroplast-generated reactive oxygen species [PDF]

PeerJ, 2016
Chloroplasts are cytoplasmic organelles for photosynthesis in eukaryotic cells. In addition, recent studies have shown that chloroplasts have a critical role in plant innate immunity against invading pathogens.

Phosphorylation-Induced Signal Propagation in the Response Regulator NtrC [PDF]

Journal of Bacteriology, 2000
ABSTRACT 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 the function of its adjacent output domain, which activates transcription by the ς 54 holoenzyme.

NtrC is required for control of Klebsiella pneumoniae NifL activity [PDF]

Journal of Bacteriology, 1997
In response to molecular oxygen and/or fixed nitrogen, the product of the Klebsiella pneumoniae nitrogen fixation L (nifL) gene inhibits NifA-mediated transcriptional activation. Nitrogen regulation of NifL function occurs at two levels: transcription of the nifLA operon is regulated by the general Ntr system, and the activity of NifL is controlled by ...
