  3. Fold a.25: Ferritin-like [47239] (6 superfamilies)
    core: 4 helices; bundle, closed, left-handed twist; 1 crossover connection

Superfamilies:

  1. a.25.1: Ferritin-like [47240] (10 families) (S)
    contains bimetal-ion centre in the middle of the bundle
  2. a.25.2: Cobalamin adenosyltransferase-like [89028] (3 families) (S)
    crossover loop goes across a different side of the 4-helical bundle; no internal metal-binding site
  3. a.25.3: EsxAB dimer-like [140453] (1 family) (S)
    (hetero)dimer of alpha-hairpin subunits similar to that of the half-ferritin family; no bound metals
  4. a.25.4: PE/PPE dimer-like [140459] (2 families) (S)
    (hetero)dimer of alpha-hairpin subunits similar to that of the half-ferritin family; no bound metals inside the bundle
