From isolation to insights: mitochondrial complex I in the diatom Phaeodactylum tricornutum [PDF]

The Plant Journal, Volume 125, Issue 3, February 2026.
SUMMARY Diatoms are among the most ecologically successful microalgae, contributing significantly to marine primary production and global carbon cycling. Their distinctive metabolic architecture, shaped by a complex evolutionary history involving secondary endosymbiosis, includes a highly compartmentalized cell organization and unique metabolic ...

Effect of Artemisinin on the Redox System of NADPH/FNR/Ferredoxin from Malaria Parasites

Antioxidants, 2022
FNR and ferredoxin constitute a redox cascade, which provides reducing power in the plastid of malaria parasites. Recently, mutation of ferredoxin (D97Y) was reported to be strongly related to the parasite’s resistance to the front-line antimalarial drug

Ferredoxin and ferredoxin–heme maquettes [PDF]

Proceedings of the National Academy of Sciences, 1996
A 16-amino acid residue peptide derived from a consensus motif of natural ferredoxins incorporates a tetranuclear iron sulfur cluster under physiological conditions. Successful assembly of the [4Fe–4S] 2+/1+ cluster within a monomeric peptide was demonstrated using size exclusion chromatography, UV-visible ...

Evolving a New Electron Transfer Pathway for Nitrogen Fixation Uncovers an Electron Bifurcating-Like Enzyme Involved in Anaerobic Aromatic Compound Degradation

mBio, 2023
Nitrogenase is the key enzyme involved in nitrogen fixation and uses low potential electrons delivered by ferredoxin (Fd) or flavodoxin (Fld) to reduce dinitrogen gas (N2) to produce ammonia, generating hydrogen gas (H2) as an obligate product of this ...

FusB Energizes Import across the Outer Membrane through Direct Interaction with Its Ferredoxin Substrate

mBio, 2020
Phytopathogenic Pectobacterium spp. import ferredoxin into the periplasm for proteolytic processing and iron release via the ferredoxin uptake system.

Pyruvate:ferredoxin oxidoreductase and low abundant ferredoxins support aerobic photomixotrophic growth in cyanobacteria

eLife, 2022
The decarboxylation of pyruvate is a central reaction in the carbon metabolism of all organisms. It is catalyzed by the pyruvate:ferredoxin oxidoreductase (PFOR) and the pyruvate dehydrogenase (PDH) complex.

Roles of Ferredoxin-Dependent Proteins in the Apicoplast of Plasmodium falciparum Parasites

mBio, 2022
Ferredoxin (Fd) and ferredoxin-NADP+ reductase (FNR) form a redox system that is hypothesized to play a central role in the maintenance and function of the apicoplast organelle of malaria parasites.

Investigation of the Ferredoxin’s Influence on the Anaerobic and Aerobic, Enzymatic H2 Production

Frontiers in Bioengineering and Biotechnology, 2021
Ferredoxins are metalloproteins that deliver electrons to several redox partners, including [FeFe] hydrogenases that are potentially a component of biological H2 production technologies.

A ferredoxin bridge connects the two arms of plant mitochondrial complex I

bioRxiv, 2020
Mitochondrial complex I is the main site for electron transfer to the respiratory chain and generates much of the proton gradient across the inner mitochondrial membrane. It is composed of two arms, which form a conserved L-shape.
