Insights into the function of NADPH thioredoxin reductase C (NTRC) based on identification of NTRC-interacting proteins in vivo [PDF]
Journal of Experimental Botany, 2019 Abstract Redox regulation in heterotrophic organisms relies on NADPH, thioredoxins (TRXs), and an NADPH-dependent TRX reductase (NTR). In contrast, chloroplasts harbor two redox systems, one that uses photoreduced ferredoxin (Fd), an Fd-dependent TRX reductase (FTR), and TRXs, which links redox regulation to light, and NTRC, which allows

NTRC and Thioredoxin f Overexpression Differentially Induces Starch Accumulation in Tobacco Leaves [PDF]
Plants, 2019 Thioredoxin (Trx) f and NADPH-dependent Trx reductase C (NTRC) have both been proposed as major redox regulators of starch metabolism in chloroplasts. However, little is known regarding the specific role of each protein in this complex mechanism. To shed light on this point, tobacco plants that were genetically engineered to overexpress the NTRC ...

Phenotype of a Rhizobium leguminosarum ntrC mutant
Research in Microbiology, 1992A Tn5 insertion mutant, strain CFN2012, of Rhizobium leguminosarum biovar phaseoli devoid of glutamine synthetase II (GSII) activity was analysed. It was shown to contain Tn5 within an 11-kb BamHI DNA fragment, which was isolated (pSM261) from the wild-type strain and, when introduced into strain CFN2012, was shown to complement the absence of GSII ...

NTRC-dependent redox balance of 2-Cys peroxiredoxins is needed for optimal function of the photosynthetic apparatus [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2017 Thiol-dependent redox regulation allows the rapid adaptation of chloroplast function to unpredictable changes in light intensity. Traditionally, it has been considered that chloroplast redox regulation relies on photosynthetically reduced ferredoxin (Fd),

Molecular recognition in the interaction of chloroplast 2‐Cys peroxiredoxin with NADPH‐thioredoxin reductase C (NTRC) and thioredoxin x [PDF]
FEBS Letters, 2014 In addition to the standard NADPH thioredoxin reductases (NTRs), plants hold a plastidic NTR (NTRC), with a thioredoxin module fused at the C-terminus. NTRC is an efficient reductant of 2-Cys peroxiredoxins (2-Cys Prxs).

NTRC new ways of using NADPH in the chloroplast
Physiologia Plantarum, 2008Despite being the primary source of energy in the biosphere, photosynthesis is a process that inevitably produces reactive oxygen species. Chloroplasts are a major source of hydrogen peroxide production in plant cells; therefore, different systems for peroxide reduction, such as ascorbate peroxidase and peroxiredoxins (Prxs), are found in this ...

X-ray crystallographic characterization and phasing of an NtrC homologue
Acta Crystallographica Section D Biological Crystallography, 2003The ZraR (HydG) protein is a 441-amino-acid protein with three functional domains and is homologous to the general nitrogen-regulatory protein NtrC that regulates nitrogen assimilation in many bacteria. The AAA and DNA-binding domains (residues 141-441) of the ZraR protein from Salmonella typhimurium were crystallized using the sitting-drop vapour ...

An ntrC homologue in B. japonicum
1987Bacteria of the species Rhizobium or Bradyrhizobium can elicit nitrogen fixing root nodules during symbiosis with certain legumes. The establishment of the symbiosis is a multi-stepped, interactive process which requires the expression of specific plant and bacterial genes. In. R. meliloti, R. leguminosarum and B.

Translational activation by an NtrC enhancer-binding protein.
Journal of molecular biology, 1998The Rhodobacter capsulatus NtrC protein is a bacterial enhancer-binding protein that activates the transcription of at least five genes by a mechanism that does not require the RpoN RNA polymerase sigma factor. The nifR3-ntrB-ntrC operon in R. capsulatus codes for the nitrogen-sensing two component regulators NtrB and NtrC, as well as for NifR3, a ...
