Iron (Fe, atomic number 26) is a redox-active transition metal element found in living systems as Fe2+ or Fe3+ ions. It is rarely found free in biology, but is bound to proteins such as ferritin or haem, to form metalloproteins such as haemoglobin, which is responsible for the transpor...
Iron is a chemical element; it has symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, just ahead of oxygen (32.1% and 30.1%, ...
The crystal structures of apo-DtxR and of the metal-ion activated form of the repressor have been solved and comparison of these structures, together with information from site-directed mutagenesis and other biochemical experiments, has allowed the identification of the activating metal-binding site(...

Especially, a lot of studies for lithium ion batteries have been made in various fields because lithium is expected to provide high energy density batteries having a light weight due to a small atomic weight of lithium and a high electromotive force due to a high ionization energy of lithium....
