Eukaryotic Ferritin (Euk_Ferritin) domain. Ferritins are the primary iron storage proteins of most living organisms and members of a broad superfamily of ferritin-like diiron-carboxylate proteins. The iron-free (apoferritin) ferritin molecule is a protein shell composed of 24 protein chains arranged in 432 symmetry. Iron storage involves the uptake of iron (II) at the protein shell, its oxidation by molecular oxygen at the dinuclear ferroxidase centers, and the movement of iron (III) into the cavity for deposition as ferrihydrite; the protein shell can hold up to 4500 iron atoms. In vertebrates, two types of chains (subunits) have been characterized, H or M (fast) and L (slow), which differ in rates of iron uptake and mineralization. Fe(II) oxidation in the H/M subunits take place initially at the ferroxidase center, a carboxylate-bridged diiron center, located within the subunit four-helix bundle. In a complementary role, negatively charged residues on the protein shell inner surface of the L subunits promote ferrihydrite nucleation. Most plant ferritins combine both oxidase and nucleation functions in one chain: they have four interior glutamate residues as well as seven ferroxidase center residues. Length = 161

Unique to this group of proteins is a third metal site in the ferroxidase center. Iron storage involves the uptake of iron (II) at the protein shell, its oxidation by molecular oxygen at the ferroxidase centers, and the movement of iron (III) into the cavity for deposition as ferrihydrite.

>PF00210 Ferritin: Ferritin-like domain; InterPro: IPR008331 Ferritin is one of the major non-haem iron storage proteins in animals, plants, and microorganisms []
It consists of a mineral core of hydrated ferric oxide, and a multi-subunit protein shell that encloses the former and assures its solubility in an aqueous environment. In animals the protein is mainly cytoplasmic and there are generally two or more genes that encode closely related subunits - in mammals there are two subunits which are known as H(eavy) and L(ight). In plants ferritin is found in the chloroplast []. This entry represents the main structural domain of ferritin. The domain is also found in other ferritin-like proteins such as members of the DNA protection during starvation (DPS) family and bacterioferritins.; GO: 0008199 ferric iron binding, 0006879 cellular iron ion homeostasis; PDB: 1N1Q_C 4DYU_E 2YJJ_D 2YJK_B 2VXX_B 3FVB_A 2WLU_A 2XGW_A 2WLA_A 1Z4A_D ....

Bacterioferritins, also known as cytochrome b1, are members of a broad superfamily of ferritin-like diiron-carboxylate proteins. Similar to ferritin in architecture, Bfr forms an oligomer of 24 subunits that assembles to form a hollow sphere with 432 symmetry. Up to 12 heme cofactor groups (iron protoporphyrin IX or coproporphyrin III) are bound between dimer pairs. The role of the heme is unknown, although it may be involved in mediating iron-core reduction and iron release. Each subunit is composed of a four-helix bundle which carries a diiron ferroxidase center; it is here that initial oxidation of ferrous iron by molecular oxygen occurs, facilitating the detoxification of iron, protection against dioxygen and radical products, and storage of ferric-hydroxyphosphate at the core. Some bacterioferritins are composed of two subunit types, one conferring heme-binding ability (alpha) and the other (beta) best
Bacterioferritin is a homomultimer most species. In Neisseria gonorrhoeae, Synechocystis PCC6803, Magnetospirillum magnetotacticum, and Pseudomonas aeruginosa, two types of subunit are found in a heteromultimeric complex, with each species having one member of each type. At present, both types of subunit are including in this single model.
DPSL (DPS-like). DPSL is a phylogenetically distinct class within the ferritin-like superfamily, and similar in many ways to the DPS (DNA Protecting protein under Starved conditions) proteins. Like DPS, these proteins are expressed in response to oxidative stress, form dodecameric cage-like particles, preferentially utilize hydrogen peroxide in the controlled oxidation of iron, and possess a short N-terminal extension implicated in stabilizing cellular DNA. This domain is a member of a broad superfamily of ferritin-like diiron-carboxylate proteins. These proteins are distantly related to bacterial ferritins which assemble 24 monomers, each of which have a four-helix bundle with a fifth shorter helix at the C terminus and a diiron (ferroxidase) center. Ferritins contain a center where oxidation of ferrous iron by molecular oxygen occurs, facilitating the detoxification of iron, protection against dioxygen and radical
