RECOMBINANT HUMAN H FERRITIN, K86Q, E27D AND E107D MUTANT
OverviewOverview
Ferritins are a family of proteins distributed widely in nature. In, bacterial, plant, and animal cells, ferritin appears to serve as a, soluble, bioavailable, and non-toxic form of iron provider. Ferritins from, animal sources are heteropolymers composed of two types of subunit, H and, L, which differ mainly by the presence (H) or absence (L) of active, ferroxidase centres. We report the crystallographic structures of four, human H apoferritin variants at a resolution of up to 1.5 Angstrom., Crystal derivatives using Zn(II) as redox-stable alternative for Fe(II), allows us to characterize the different metal-binding sites. The, ferroxidase centre, which is composed of sites A and B, binds metal with a, preference for the A site. In addition, distinct Zn(II)-binding sites were, found in ... [(full description)]
