NTRC-dependent redox balance of 2-Cys peroxiredoxins is needed for optimal function of the photosynthetic apparatus
(National Academy of Sciences, 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 ...

Molecular cloning and biochemical characterization of three phosphoglycerate kinase isoforms from developing sunflower (Helianthus annuus L.) seeds
(Elsevier, 2012)
Three cDNAs encoding different phosphoglycerate kinase (PGK, EC 2.7.2.3) isoforms, two cytosolic (HacPGK1 and HacPGK2) and one plastidic (HapPGK), were cloned and characterized from developing sunflower (Helianthus annuus ...

NTRC Plays a Crucial Role in Starch Metabolism, Redox Balance, and Tomato Fruit Growth
(American Society of Plant Biologists, 2019)
NADPH-thioredoxin reductase C (NTRC) forms a separate thiol-reduction cascade in plastids, combining both NADPHthioredoxin reductase and thioredoxin activities on a single polypeptide. While NTRC is an important regulator ...

Electron Transfer Pathways and Dynamics of Chloroplast NADPH-dependent Thioredoxin Reductase C (NTRC)
(American Society for Biochemistry and Molecular Biology, 2012)
NADPH-dependent thioredoxin reductases (NTRs) contain a flavin cofactor and a disulfide as redox-active groups. The catalytic mechanism of standard NTR involves a large conformational change between two configurations. ...

Plant responses to fungal volatiles involve global posttranslational thiol redox proteome changes that affect photosynthesis
(Wiley-Blackwell, 2019)
Microorganisms produce volatile compounds (VCs) that promote plant growth and photosynthesis through complex mechanisms involving cytokinin (CK) and abscisic acid (ABA). We hypothesized that plants' responses to microbial ...

Chloroplast redox homeostasis is essential for lateral root formation in Arabidopsis
(Taylor & Francis, 2012)
Redox regulation based on dithiol-disulphide interchange is an essential component of the control of chloroplast metabolism. In contrast to heterotrophic organisms, and non-photosynthetic plant tissues, chloroplast redox ...

Redox-control of chlorophyll biosynthesis mainly depends on thioredoxins
(Wiley-Blackwell, 2018)
In order to maintain enzyme stability and activity, chloroplasts use two systems of thiol-disulfide reductases for the control of redox-dependent properties of proteins. Previous studies have revealed that plastid-localized ...

Thioredoxin f1 and NADPH-dependent thioredoxin reductase C have overlapping functions in regulating photosynthetic metabolism and plant growth in response to varying light conditions
(American Society of Plant Biologists, 2015)
Two different thiol-redox-systems exist in plant chloroplasts, the ferredoxin-thioredoxin system, which depends of ferredoxin reduced by the photosynthetic electron-transport chain and, thus, of light, and the NADPH-dependent ...

Molecular recognition in the interaction of chloroplast 2-Cys peroxiredoxin with NADPH-thioredoxin reductase C (NTRC) and thioredoxin x
(Elsevier, 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). ...

An intermolecular disulfide-based light switch for chloroplast psbD gene expression in Chlamydomonas reinhardtii
(Taylor & Francis, 2012)
Expression of the chloroplast psbD gene encoding the D2 protein of the photosystem II reaction center is regulated by light. In the green alga Chlamydomonas reinhardtii, D2 synthesis requires a high-molecular-weight complex ...
