Ferritin exhibits complex behavior in the ultracentrifuge due to variability in iron core size among molecules. A comprehensive study was undertaken to develop procedures for obtaining more uniform cores and assessing their homogeneity.Analytical ult

The x-ray crystal structure of the N-lobe of human serum transferrin has shown that there is a hydrogen bond network, the so-called “second shell,” around the transferrin iron binding site. Tyrosine at position 85 and glutamic acid at position 83

Human serum transferrin N-lobe (hTF/2N) has four iron-binding ligands, including one histidine, one aspartate, and two tyrosines. The present report elucidates the inequivalence of the two tyrosine ligands (Tyr 95 and Tyr 188) on the metal-binding pr

During its metabolism, vanadium is known to become associated with the iron storage protein, ferritin. To elucidate probable vanadium binding sites on the protein, VO 2+ binding to mammalian ferritins was studied using site-directed mutagenesis and E

The effects of site-directed mutation and salt on the iron(III)-binding site of the recombinant half-molecule of the N-terminal lobe (hTf/2N) of human transferrin was studied by EPR spectroscopy. Changes were observed in the EPR spectra of all varian

Salts are known to have a pronounced effect on the spectroscopic, thermodynamic and kinetic properties of human serum transferrin. The present study was undertaken to examine the effect of NaCl on the related proteins ovotransferrin and lactoferrin.

A number of recent studies have implicated the involvement of ferritin iron in oxygen radical reactions. Hemosiderin has long been thought to be a degradation product of ferritin. A recent series of papers have indicated that oxygen radical damage to

The chemistry of oxidative deposition of iron(III) in ferritin and apoferritin is poorly understood. This study was undertaken to look for radicals formed as the hydrous ferric oxide core is developed from Fe(II) and O2. Radicals were observed indire
