Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism

Plant Direct, Volume 9, Issue 8, August 2025.
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

Structural insight into the high reduction potentials observed for Fusobacterium nucleatum flavodoxin

Protein Science, 2019
Flavodoxins are small flavin mononucleotide (FMN)‐containing proteins that mediate a variety of electron transfer processes. The primary sequence of flavodoxin from Fusobacterium nucleatum, a pathogenic oral bacterium, is marked with a number of distinct

Mapping the interactions between flavodoxin and its physiological partners flavodoxin reductase and cobalamin-dependent methionine synthase [PDF]

Proceedings of the National Academy of Sciences, 2001
Flavodoxins are electron-transfer proteins that contain the prosthetic group flavin mononucleotide. In Escherichia coli , flavodoxin is reduced by the FAD-containing protein NADPH:ferredoxin (flavodoxin) oxidoreductase; flavodoxins serve as electron donors in the reductive activation of ...

Phenolic Iron Complexes Protect Glacier Ice Algae (Zygnematophyceae) Against Excessive UV and VIS Irradiation

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
We brought evidence that glacier ice alga Ancylonema alaskanum (Zygnematophceae) sequesters iron and forms organic metal complexes. We found that phenols were already present in the green Ancylonema alaskanum laboratory strain. Our study showed that their vacuole turned brownish due to enhanced iron‐phenol complexation under nutrient limitation with ...

Flavodoxin and NADPH-flavodoxin reductase from Escherichia coli support bovine cytochrome P450c17 hydroxylase activities.

Journal of Biological Chemistry, 1994
Two soluble flavoproteins, purified from Escherichia coli cytosol and identified as flavodoxin and NADPH-flavodoxin (ferredoxin) reductase (flavodoxin reductase), have been found in combination to support the 17 alpha-hydroxylase activities of heterologously expressed bovine 17 alpha-hydroxylase cytochrome P450 (P450c17).

From aerial drone to quantitative trait locus: leveraging next‐generation phenotyping to reveal the genetics of color and height in field‐grown Lactuca sativa

The Plant Journal, Volume 123, Issue 3, August 2025.
SUMMARY In recent years, accurate and low‐cost variant calling has enabled the genotyping of large diversity panels for genome‐wide association studies. As a result, phenotyping rather than genotyping is now the rate‐limiting step, especially in field experiments.

Reduction of Flavodoxin by Electron Bifurcation and Sodium Ion-dependent Reoxidation by NAD+ Catalyzed by Ferredoxin-NAD+ Reductase (Rnf)*

Journal of Biological Chemistry, 2016
Electron-transferring flavoprotein (Etf) and butyryl-CoA dehydrogenase (Bcd) from Acidaminococcus fermentans catalyze the endergonic reduction of ferredoxin by NADH, which is also driven by the concomitant reduction of crotonyl-CoA by NADH, a process ...

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

The Characterization of Different Flavodoxin Reductase-Flavodoxin (FNR-Fld) Interactions Reveals an Efficient FNR-Fld Redox Pair and Identifies a Novel FNR Subclass.

Biochemistry, 2018
Flavodoxins (Flds) are small, bacterial proteins that transfer electrons to various redox enzymes. Flavodoxins are reduced by ferredoxin/flavodoxin NADP+ oxidoreductases (FNRs), but little is known of the FNR-Fld interaction.
