Protein attributes
| Sequence length | 259 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation By similarity. |
| Catalytic activity | 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O. |
| Subunit structure | Oligomer of 24 subunits. There are two types of subunits: L (light) chain and H (heavy) chain. The major chain can be light or heavy, depending on the species and tissue type. The functional molecule forms a roughly spherical shell with a diameter of 12 nm and contains a central cavity into which the insoluble mineral iron core is deposited By similarity. |
| Subcellular location | Plastid › chloroplast By similarity. |
| Sequence similarities | Belongs to the ferritin family. Contains 1 ferritin-like diiron domain. |
