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.
借助定点诱变技术对人重链铁蛋白中的亚铁氧化酶活性进行了研究。通过X射线晶体学发现的一个位点现已被确定为亚铁氧化酶中心。该中心仅存在于重链中，位于链折叠的四螺旋束内。
