Effect of Ferredoxin on the Diaphorase Activity of Cyanobacterial Ferredoxin-NADP Reductase [PDF]

open access: yesPlant Physiology, 1985
The interaction of ferredoxin-NADP reductase (FNR) and ferredoxin (Fd) results in an enhanced rate of reaction and a shift of the pH optimum for the FNR-mediated diaphorase reaction. Low concentrations of NaCl (

Evolutionary insights into bilin biosynthesis: Functional characterization of pre‐PcyA enzymes

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Biosynthesis of the linear tetrapyrrole phycocyanobilin (PCB) by the ferredoxin‐dependent bilin reductase (FDBR) PcyA is essential for light‐harvesting and regulatory processes in diverse photosynthetic organisms, yet its evolutionary origins are not fully understood. PcyA evolved from pre‐PcyA proteins found in diverse bacteria.

Flavin-Based Electron Bifurcation, Ferredoxin, Flavodoxin, and Anaerobic Respiration With Protons (Ech) or NAD+ (Rnf) as Electron Acceptors: A Historical Review

open access: yesFrontiers in Microbiology, 2018
Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more ...

Improving Activity and Stability of Candida boidinii Formate Dehydrogenase Through Rational Active Site Engineering

open access: yesChemBioChem, Volume 27, Issue 15, 14 August 2026.
In search of improved biocatalysts for the NADH cofactor recycling in synthetic reductive biotransformations, C. boidinii formate dehydrogenase is the subject of a rational protein engineering approach. The study delivers an enzyme variant with improved specific activities and a more desirable pH and temperature profile, which shows promising ...

Identification of Early Salt-Stress-Responsive Proteins in In Vitro Prunus Cultured Excised Roots

open access: yesPlants, 2022
Fruit-tree rootstock selection is a challenge under a scenario of growing environmental stresses in which the soil and climate are greatly affected. Salinization is an increasing global process that severely affects soil fertility.

Advancing the Resolution of the Sulfur Compound Disproportionation Puzzle in Dissulfuribacter Thermophilus S69ᵀ Through Quantitative Label‐Free Comparative Proteomics

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 4, August 2026.
To date, only three microorganisms have been functionally characterised for sulfur disproportionation. Our work identifies a fourth example and provides novel proteomic insights into its underlying pathways. These findings advance our understanding of microbial sulfur catabolism and highlight the ecological role of D.

Heterologous ferredoxin reductase and flavodoxin protect Cos-7 cells from oxidative stress. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Ferredoxin-NADP(H) reductase (FNR) from Pisum sativum and Flavodoxin (Fld) from Anabaena PCC 7119 have been reported to protect a variety of cells and organisms from oxidative insults.

Open questions in ferredoxin‐NADP+ reductase catalytic mechanism [PDF]

open access: yesEuropean Journal of Biochemistry, 2003
Ferredoxin (flavodoxin)‐NADP(H) reductases (FNR) are ubiquitous flavoenzymes that deliver NADPH or low potential one‐electron donors (ferredoxin, flavodoxin) to redox‐based metabolisms in plastids, mitochondria and bacteria. The plant‐type reductase is also the basic prototype for one of the major families of flavin‐containing electron transferases ...

Biochemical characterization of ferredoxin-NADP+ reductase interaction with flavodoxin in Pseudomonas putida [PDF]

open access: yesBMB Reports, 2012
Flavodoxin (Fld) has been demonstrated to bind to ferredoxin-NADP+ reductase A (FprA) in Pseudomonas putida. Tworesidues (Phe256, Lys259) of FprA are likely to be important forinteracting with Fld based on homology modeling.

Thioredoxin reductase from Bacillus cereus exhibits distinct reduction and NADPH‐binding properties

open access: yesFEBS Open Bio, 2021
Low‐molecular‐weight (low Mr) thioredoxin reductases (TrxRs) are homodimeric NADPH‐dependent dithiol flavoenzymes that reduce thioredoxins (Trxs) or Trx‐like proteins involved in the activation networks of enzymes, such as the bacterial class Ib ...
