Inactivation of clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase by sodium nitrite [PDF]

Applied and Environmental Microbiology, 1987
Clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase activity was investigated after in vitro or in vivo treatment with sodium nitrite. In vitro treatment of commercially available Clostridium pasteurianum ferredoxin with sodium nitrite inhibited ferredoxin activity.

A Case of Multiple Mitochondrial Dysfunctions Syndrome 1 and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple mitochondrial dysfunctions syndrome 1 (MMDS1, MIM #605711) due to NFU1 gene defects is an ultra‐rare autosomal recessive inborn error of metabolism associated with reduced function of NFU1 iron–sulfur cluster (ISC) scaffold protein.

The Transfer of the Ferredoxin Gene From the Chloroplast to the Nuclear Genome Is Ancient Within the Paraphyletic Genus Thalassiosira

Frontiers in Microbiology, 2020
Ferredoxins are iron–sulfur proteins essential for a wide range of organisms because they are an electron transfer mediator involved in multiple metabolic pathways. In phytoplankton, these proteins are active in the mature chloroplasts, but the petF gene,

Unique flexibility in energy metabolism allows mycobacteria to combat starvation and hypoxia. [PDF]

PLoS ONE, 2010
Mycobacteria are a group of obligate aerobes that require oxygen for growth, but paradoxically have the ability to survive and metabolize under hypoxia. The mechanisms responsible for this metabolic plasticity are unknown.

Entdeckung eines antiviralen Elektronentransferprozesses zur Erzeugung katalytisch selbstversorgender viraler Restriktionsfaktoren

Angewandte Chemie, EarlyView.
CYB5R3 wird als mutmaßlicher Elektronentransferpartner von Viperin (RSAD2) identifiziert, was erklärt, warum die ER‐Lokalisation für die antivirale Aktivität erforderlich ist. Dieses Wissen ermöglichte die Entwicklung immunstiller, katalytisch selbstversorgender antiviraler Restriktionsfaktor‐Enzyme (iCAREs), die ein antivirales Nukleosidtriphosphat ...

Discovery of an Antiviral Electron Transfer Process to Create Catalytically Self‐Sufficient Viral Restriction Factors

Angewandte Chemie International Edition, EarlyView.
CYB5R3 is identified as a putative electron‐transfer partner of viperin (RSAD2), explaining why ER localisation is required for antiviral activity. Its utilisation enabled the engineering of immune‐silent, catalytically self‐sufficient antiviral restriction factor enzymes (iCAREs) that produce an antiviral nucleoside triphosphate analogue (ANTA ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Ferredoxins: master regulators in mitochondrial redox homeostasis and programmed cell death

Redox Biology
Ferredoxins (FDXs) are evolutionarily conserved iron-sulfur (Fe–S) proteins that serve as master regulators of mitochondrial redox homeostasis, governing critical processes including electron transfer, energy metabolism, Fe–S cluster biogenesis, and ...

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

Plant 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 (
