ferritin, mitochondrial [Otolemur garnettii]

Protein Classification

ferritin( domain architecture ID 10099405)

ferritin is the primary iron storage protein of most living organisms and belongs to a broad superfamily of ferritin-like diiron-carboxylate proteins. The iron-free (apoferritin) ferritin molecule is a protein shell composed of 24 protein chains. 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.

eukaryotic ferritins; 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.

 76-232 6.20e-33

nonheme-containing ferritins; Nonheme Ferritin domain, found in archaea and bacteria, is a member of a broad superfamily of ferritin-like diiron-carboxylate proteins. The ferritin protein shell is composed of 24 protein subunits arranged in 432 symmetry. Each protein subunit, a four-helix bundle with a fifth short terminal helix, contains a dinuclear ferroxidase center (H type). 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.

 77-193 1.23e-06

Ferritin-like superfamily of diiron-containing four-helix-bundle proteins; Ferritin-like, diiron-carboxylate proteins participate in a range of functions including iron regulation, mono-oxygenation, and reactive radical production. These proteins are characterized by the fact that they catalyze dioxygen-dependent oxidation-hydroxylation reactions within diiron centers; one exception is manganese catalase, which catalyzes peroxide-dependent oxidation-reduction within a dimanganese center. Diiron-carboxylate proteins are further characterized by the presence of duplicate metal ligands, glutamates and histidines (ExxH) and two additional glutamates within a four-helix bundle. Outside of these conserved residues there is little obvious homology. Members include bacterioferritin, ferritin, rubrerythrin, aromatic and alkene monooxygenase hydroxylases (AAMH), ribonucleotide reductase R2 (RNRR2), acyl-ACP-desaturases (Acyl_ACP_Desat), manganese (Mn) catalases, demethoxyubiquinone hydroxylases (DMQH), DNA protecting proteins (DPS), and ubiquinol oxidases (AOX), and the aerobic cyclase system, Fe-containing subunit (ACSF).

Bacterioferritin, ferritin-like diiron-binding domain; 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) bestowing ferroxidase activity.
