Fold: Ferritin-like

core: 4 helices; bundle, closed, left-handed twist; 1 crossover connection

Lineage:

  1. Root: scop
  2. Class: All alpha proteins [46456]
  3. Fold: Ferritin-like [47239]
    core: 4 helices; bundle, closed, left-handed twist; 1 crossover connection

Superfamilies:

  1. Ferritin-like [47240] (5) picpic
    contains bimetal-ion centre in the middle of the bundle
  2. Cobalamin adenosyltransferase-like [89028] (2) picpic
    crossover loop goes across a different side of the 4-helical bundle; no internal metal-binding site
  3. EsxAB dimer-like [140453] (1) picpic
    (hetero)dimer of alpha-hairpin subunits similar to that of the half-ferritin family; no bound metals
  4. PE/PPE dimer-like [140459] (2) picpic
    (hetero)dimer of alpha-hairpin subunits similar to that of the half-ferritin family; no bound metals inside the bundle
