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.

Arabidopsis Iron Superoxide Dismutase FSD1 Protects Against Methyl Viologen-Induced Oxidative Stress in a Copper-Dependent Manner

Frontiers in Plant Science, 2022
Iron superoxide dismutase 1 (FSD1) was recently characterized as a plastidial, cytoplasmic, and nuclear enzyme with osmoprotective and antioxidant functions. However, the current knowledge on its role in oxidative stress tolerance is ambiguous.

Towards the spatial resolution of metalloprotein charge states by detailed modeling of XFEL crystallographic diffraction. [PDF]

, 2020
Oxidation states of individual metal atoms within a metalloprotein can be assigned by examining X-ray absorption edges, which shift to higher energy for progressively more positive valence numbers.

Looking for the mechanism of arsenate respiration of Fusibacter sp. strain 3D3, independent of ArrAB

Frontiers in Microbiology, 2022
The literature has reported the isolation of arsenate-dependent growing microorganisms which lack a canonical homolog for respiratory arsenate reductase, ArrAB.

Contribution to the Understanding of Protein–Protein Interface and Ligand Binding Site Based on Hydrophobicity Distribution—Application to Ferredoxin I and II Cases

Applied Sciences, 2021
Ferredoxin I and II are proteins carrying a specific ligand—an iron-sulfur cluster—which allows transport of electrons. These two classes of ferredoxin in their monomeric and dimeric forms are the object of this work.

Structure of the atypical bacteriocin pectocin M2 implies a novel mechanism of protein uptake [PDF]

, 2014
The colicin-like bacteriocins are potent protein antibiotics that have evolved to efficiently cross the outer membrane of Gram-negative bacteria by parasitizing nutrient uptake systems.

Side chain hydroxylation of C27-steroids and vitamin D3 by a cytochrome P-450 enzyme system isolated from human liver mitochondria

Journal of Lipid Research, 1981
The present study was undertaken to obtain information on the involvement of cytochrome P-450 in the 26-hydroxylation on bile acid intermediates and in the 25-hydroxylation of vitamin D3 in human liver mitochondria.
