>gnl|CDD|153114 cd01056, Euk_Ferritin, 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.

>gnl|CDD|153113 cd01055, Nonheme_Ferritin, 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.

>gnl|CDD|153097 cd00657, Ferritin_like, 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).
