This domain is found in found in uncharacterised proteins predominantly from bacteria. The uncharacterised Swiss:Q9I1U6 from Pseudomonas aeruginosa shows a ferritin-like topology with a four-helix-bundle fold that lacks metal-ion-binding site typical of the ferritin family (Pfam:PF00210) but has a potential metal-binding site [1]. The function is unknown.	Domain
