Recent insights into antioxidant defenses of legume root nodules [PDF]

open access: yes, 2010
43 Pag., 2 Tabl., 2 Fig. The definitive version is available at: www3.interscience.wiley.comLegume root nodules are sites of intense biochemical activity and consequently are at high risk of damage as a result of the generation of reactive oxygen ...

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

open access: yesJournal 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 ...

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

open access: yesEnvironmental 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 ...

Radical SAM enzyme QueE defines a new minimal core fold and metal-dependent mechanism [PDF]

open access: yes, 2013
7-carboxy-7-deazaguanine synthase (QueE) catalyzes a key S-adenosyl-L-methionine (AdoMet)- and Mg[superscript 2+]-dependent radical-mediated ring contraction step, which is common to the biosynthetic pathways of all deazapurine-containing compounds. QueE

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

open access: yesBiochemistry, 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.

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

open access: yesThe 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.

Diel transcriptional response of a California Current plankton microbiome to light, low iron, and enduring viral infection. [PDF]

open access: yes, 2019
Phytoplankton and associated microbial communities provide organic carbon to oceanic food webs and drive ecosystem dynamics. However, capturing those dynamics is challenging. Here, an in situ, semi-Lagrangian, robotic sampler profiled pelagic microbes at

Amino Acid Sequences of Clostridium pasteurianum Flavodoxin

open access: yesZeitschrift für Naturforschung B, 1972
The amino acid sequences of 10 tryptic peptides from C. pasteurianum flavodoxin are determined and ordered. The sequence of two thirds of the protein is presented. New electrophoretic techniques for sequence determination are also presented.

High‐resolution crystal structures reveal a mixture of conformers of the Gly61‐Asp62 peptide bond in an oxidized flavodoxin from Bacillus cereus

open access: yesProtein Science, 2018
Flavodoxins (Flds) are small proteins that shuttle electrons in a range of reactions in microorganisms. Flds contain a redox‐active cofactor, a flavin mononucleotide (FMN), and it is well established that when Flds are reduced by one electron, a peptide ...
