Oligomerization of NTRC at the glnA enhancer is required for transcriptional activation. [PDF]
Genes & Development, 1993 To activate transcription of the glnA gene, the dimeric NTRC protein (nitrogen regulatory protein C) of enteric bacteria binds to an enhancer located approximately 100 bp upstream of the promoter. The enhancer is composed of two binding sites for NTRC that are three turns of the DNA helix apart.

Towards Finding a Better Reaction Coordinate: NtrC and DIMS [PDF]
Biophysical Journal, 2011 All atom molecular dynamics is appealing due to the detailed insights towards protein function. But, all-atom molecular dynamics is limited due to the small amount of time spent in the transitions between stable states. Dynamic importance sampling (DIMS) enhances this sampling problem by biasing, with correction, to encourage sampling away from the ...

Antioxidants, 2018 Thiol-based redox control is one of the important posttranslational mechanisms of the tetrapyrrole biosynthesis pathway. Many enzymes of the pathway have been shown to interact with thioredoxin (TRX) and Nicotinamide adenine dinucleotide phosphate (NADPH)

DNA Microarray-Based Identification of Genes Regulated by NtrC in Bradyrhizobium japonicum [PDF]
Applied and Environmental Microbiology, 2015 ABSTRACT The Bradyrhizobium japonicum NtrBC two-component system is a critical regulator of cellular nitrogen metabolism, including the acquisition and catabolism of nitrogenous compounds. To better define the roles of this system, genome-wide transcriptional profiling was performed to identify the NtrC ...

Protein kinase and phosphoprotein phosphatase activities of nitrogen regulatory proteins NTRB and NTRC of enteric bacteria: roles of the conserved amino-terminal domain of NTRC. [PDF]
Proceedings of the National Academy of Sciences, 1988 The NTRC protein (ntrC product) of enteric bacteria activates transcription of nitrogen-regulated genes by a holoenzyme form of RNA polymerase that contains the ntrA product (sigma 54) as sigma factor. Although unmodified NTRC will bind to DNA, it must be phosphorylated to activate transcription. Both phosphorylation and dephosphorylation of NTRC occur

Regulation of CP12-mediated carbon metabolism by NTRC during cold acclimation [PDF]
, 2021 In plant and algal chloroplasts redox regulation is essential for the rapid adaptation of metabolism in response to changing light conditions. NADPH-dependent thioredoxin reductase C (NTRC) is known as an alternative to the classical ferredoxin ...

, 2023 In plant chloroplasts, thiol regulation is driven by two systems. One relies on the activity of thioredoxins through their light dependent reduction by ferredoxin via a ferredoxin-thioredoxin reductase (FTR).

The Xcc XibR and NtrC are two functionally distinct homologs of NtrC family proteins.
, 2016 (A) Multiple sequence alignment of XibR and NtrC of Xcc. Sequence alignment was performed by using CLUSTALW. Asterisks indicate identical amino acids; (:) indicate highly conserved and (.) less conserved.
