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

Plastidchloroplast inner membrane. Note: And other plastids. Ref.1

Tissue specificity

Leaves. Ref.1

Miscellaneous

On the 2D-gel the determined pI of this protein is: 4.74, its MW is: 25.7 kDa.

Sequence similarities

Belongs to the ferritin family. UniProtKB P19975
