Identification of the ferroxidase centre in ferritin

FEBS Lett. 1989 Aug 28;254(1-2):207-10. doi: 10.1016/0014-5793(89)81040-3.

Abstract

Ferroxidase activity in human H-chain ferritin has been studied with the aid of site-directed mutagenesis. A site discovered by X-ray crystallography has now been identified as the ferroxidase centre. This centre is present only in H-chains and is located within the four-helix bundle of the chain fold.
