| Abstract | Ferritin is one of the major non-haem iron storage proteins in animals, plants, and microorganisms. Ferritin is a multisubunit protein with a hollow interior, which contains a mineral core of hydrated ferric oxide, thereby ensuring its solubility in an aqueous environment [ 9668036]. Each subunit consists of a closed, four-helical bundle with a left-handed twist and one crossover connection.
This family contains ferritin and other ferritin-like proteins such as bacterioferritin (cytochrome b1) that binds haem between two subunits, non-haem ferritin, dodecameric ferritin homologue (DPS) that binds to and protects DNA, and the N-terminal domain of rubrerythrin that is found in many air-sensitive bacteria and archaea [12175244]. In addition, ribonucleotide reductase-like proteins show a similar structure to the ferritin-like fold; these di-iron carboxylate proteins constitute a diverse class of non-haem iron enzymes performing a multitude of redox reactions [11315567]. This family includes the alpha and beta subunits of methane monooxygenase hydrolase, delta 9-stearoyl-acyl carrier protein desaturase and manganese catalase (T-catalase). |

Alignments of sequences to 58 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have
different domain combinations including a Ferritin-like domain.
|
Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
|
|
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
