The Functionality of the three-sited Ferroxidase center of E. coli Bacterial Ferritin (EcFtnA) [PDF]

, 2014
At least three ferritins are found in the bacterium Escherichia coli, the heme-containing bacterioferritin (EcBFR) and two non-heme bacterial ferritins (EcFtnA and EcFtnB).

The Distribution of Ferritins in Marine Copepods

Journal of Marine Science and Engineering, 2023
Iron is an essential element for the functioning of cellular processes. Ferritins, the major intracellular iron storage proteins, convert the free Fe2+ into the nontoxic Fe3+ which can be stored and transported where needed.

Reaction of O2 with a di-iron protein generates a mixed valent Fe2+/Fe3+ center and peroxide [PDF]

, 2019
The gene encoding the cyanobacterial ferritin SynFtn is up-regulated in response to copper stress. Here, we show that, while SynFtn does not interact directly with copper, it is highly unusual in several ways.

Conservation of the structural and functional architecture of encapsulated ferritins in bacteria and archaea

bioRxiv, 2018
Iron is an essential element for many biological processes; however, due to its high reactivity iron can also be very toxic, producing reactive oxygen species through Fenton chemistry.

Iron deficiency anemia improved by dental implantation: A case report

Saudi Journal of Medicine and Medical Sciences, 2022
Treatments for improving iron deficiency anemia are generally aimed at increasing oral iron intake and/or administration. Such treatments, however, have been unsuccessful in managing nutritional disorders, including anemia, in patients with masticatory ...

Iron Oxidation and Core Formation in Recombinant Heteropolymeric Human Ferritins.

Biochemistry, 2017
In animals, the iron storage and detoxification protein, ferritin, is composed of two functionally and genetically distinct subunit types, H (heavy) and L (light), which co-assemble in various ratios with tissue specific distributions to form shell-like ...

Structural characterization of encapsulated ferritin provides insight into iron storage in bacterial nanocompartments

eLife, 2016
Ferritins are ubiquitous proteins that oxidise and store iron within a protein shell to protect cells from oxidative damage. We have characterized the structure and function of a new member of the ferritin superfamily that is sequestered within an ...

Quantification of Ferritin from Staple Food Crops [PDF]

, 2009
Ferritin-iron has been shown to be as bioavailable as ferrous sulfate in humans. Thus, biofortification to breed crops with high ferritin content is a promising strategy to alleviate the global iron deficiency problem. Although ferritin is present in all

The importance of eukaryotic ferritins in iron handling and cytoprotection.

Biochemical Journal, 2015
Ferritins, the main intracellular iron storage proteins, have been studied for over 60 years, mainly focusing on the mammalian ones. This allowed the elucidation of the structure of these proteins and the mechanisms regulating their iron incorporation ...
