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 ...

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.
