SUMMARYTransferrin is the major iron transport protein of mammalian plasma. The ultraviolet-B irradiation of 1.4 mg/ml iron saturated transferrin solutions (~32 μM Fe3+) induces a Fe3+ loss accompanied by Fe2+ formation. The initial quantum yield of Fe3+ loss is wavelength dependent (φ(313 nm)~1.3×10?3) and oxygen independent suggesting an intramolecular electron transfer from one of the Fe3+ ligands. A photolysis of tryptophan residues parallels this photoreduction. 相似文献
