Function[FRIL_HORSE] Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedHybridization of metal complexes and protein scaffolds is an important subject in bioinorganic chemistry and materials science. Efforts to provide non-natural functions to proteins will likely lead to advances in development of catalysts, sensors, and so on. Mechanistic investigations of the process of binding of metal complexes within protein scaffolds and characterization of the resulting coordination structures will help us to design and control coordination structures of metal complexes for construction of hybrid proteins containing metal complexes. In this work, the processes of accumulation and incorporation of organometallic palladium complexes within the cage of the iron storage protein apo-ferritin (apo-Fr) are elucidated by analysis of X-ray crystal structures of apo-Fr and selected mutants thereof, in the presence of the metal complexes. The crystal structure of apo-Fr containing Pd(allyl) (allyl = eta(3)-C(3)H(5)) complexes shows that thiolato-bridged dinuclear Pd(allyl) complexes are formed at two binding sites within the cage of apo-Fr. The crystal structures of apo-Fr and its Cys- and His-deletion mutants containing Pd(allyl) complexes indicate that Cys126 accelerates the incorporation of Pd(allyl) complexes into the cage. In addition, Cys48 and Cys126 are essential for accumulation of Pd(allyl) complexes and stabilizing the square planar coordination structure.
