Superfamily: Periplasmic metal-binding protein Tp34-type

Structural domains comprising this superfamily share the structure of the bacterial periplasmic metal-binding protein Tp34. It is believed that Tp34, together with a group of uncharacterised proteins, are involved in high affinity Fe2+ transport. However, the structural and functional aspects of this group of proteins is yet to be determined.

It has been proposed that Tp34 binds zinc and the iron-sequestering lactoferrin PMID:17192261 and that it has a role in metal ion homeostasis PMID:23042995.
