AB  - Transferrins transport Fe3+ and other metal ions in mononuclear-binding sites. We
      present the first evidence that a member of the transferrin superfamily is able
      to recognize multi-nuclear oxo-metal clusters, small mineral fragments that are
      the most abundant forms of many metals in the environment. We show that the
      ferric ion-binding protein from Neisseria gonorrhoeae (nFbp) readily binds
      clusters of Fe3+, Ti4+, Zr4+ or Hf4+ in solution. The 1.7 A resolution crystal
      structure of Hf-nFbp reveals three distinct types of clusters in an open,
      positively charged cleft between two hinged protein domains. A di-tyrosyl cluster
      nucleation motif (Tyr195-Tyr196) is situated at the bottom of this cleft and
      binds either a trinuclear oxo-Hf cluster, which is capped by phosphate, or a
      pentanuclear cluster, which in turn can be capped with phosphate. This first
      high-resolution structure of a protein-mineral interface suggests a novel
      metal-uptake mechanism and provides a model for protein-mediated
      mineralization/dissimilation, which plays a critical role in geochemical
      processes.
