Iron uptake byBifidobacterium thermophilum protoplasts
Biological Trace Element Research, 1993Protoplasts of Bifidobacterium thermophilum were prepared by a combination of lysozyme and protease digestion, and ferrous iron uptake studies were carried out. Little, if any, iron was internalized by the protoplasts, although large amounts of iron were bound to the protoplast surface.

Critical Reviews in Biochemistry and Molecular Biology, 1999
Recent information gained from genetic and biochemical studies of iron transport in yeast, coupled with the identification of specific mutations causing iron uptake disorders in mice and man, has provided new clues about the mechanisms involved in iron uptake.

Monitoring Iron Uptake by Siderophores
2014Iron is an important element for almost all forms of life. In order to get access to this essential nutriment, Pseudomonads produce two major siderophores, pyoverdine PVD and pyochelin (PCH). Uptake of iron in bacterial cells can be monitored accurately using (55)Fe.

Iron Uptake by Rabbit Reticulocytes
British Journal of Haematology, 1973Summary. In keeping with present concepts of internal iron exchange, it is thought that the two iron binding sites of transferrin molecules bind and donate iron in a similar manner. Since recent data, however, have suggested that iron attached at one iron binding site may be more readily available to cells than iron bound to the other site, a further ...

Iron uptake by mammalian cortical neurons
Annals of Neurology, 1984AbstractAlthough iron accumulates in the brain in a number of pathological conditions, including Hallervorden‐Spatz syndrome, Parkinson's disease, and neurosyphilis, studies of brain iron metabolism have been performed only rarely. Neuronal‐enriched cultures were prepared from fetal mouse brain. After 18 days the cells were exposed to radiolabeled iron.

Ferritin and iron uptake by reticulocytes
British Journal of Haematology, 1983Summary.The uptake of liver ferritin labelled with 125I or 59Fe by guinea‐pig reticulocytes has been studied to investigate the characteristics of the uptake process, compare it with transferrin uptake and determine whether ferritin‐iron is utilized by the cells in haem synthesis.

Iron uptake regulation in Pseudomonas aeruginosa
BioMetals, 2009The Pseudomonas genus belongs to the gamma division of Proteobacteria and many species produce the characteristic yellow-green siderophore pyoverdine, and often a second siderophore, of lower affinity for iron. These bacteria are known for their ability to colonize different ecological niches and for their versatile metabolism.

Hepatic Ferritin Uptake and Hepatic Iron
Hepatology, 1990The effect of hepatic iron on the uptake of ferritin was studied by perfusing livers from normal, iron deficient and iron–loaded rats with 125I–labeled ferritin. Unlabeled ferritin with tracer doses of labeled ferritin in concentrations of 0.02 to 2,700 nmol/L were studied.

At the normal pH range of arable soils, available Fe is not enough to meet plant requirement. Deficiency of Fe occurs less in acid soils than calcareous soils with higher pH. Iron deficiency is a major health problem for humans around the world.

Iron uptake in Salmonella typhimurium
Canadian Journal of Microbiology, 1971The iron-uptake system of S. typhimurium is energy-dependent, repressed by growth in the presence of iron, and apparently specific for iron. Iron uptake is stimulated by a sideramine and by phenolic acids. In mutants unable to synthesize enterobactin, the uptake system remains functional. Iron inside the cell is not available to external chelators.
