Protein

Ferritin-1, chloroplastic

Gene

FER1

Organism
Zea mays (Maize)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.

Expressioni

Tissue specificityi

Ferritins accumulate in seed during maturation. Then, they are degraded during the first days of germination. Present in roots and leaves after iron treatment.

Inductioni

By iron.

Interactioni

Subunit structurei

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.
