Fold: Double-stranded beta-helix

one turn of helix is made by two pairs of antiparallel strands linked with short turns
has appearance of a sandwich of distinct architecture and jelly-roll topology

Lineage:

  1. Root: scop
  2. Class: All beta proteins [48724]
  3. Fold: Double-stranded beta-helix [51181]
    one turn of helix is made by two pairs of antiparallel strands linked with short turns
    has appearance of a sandwich of distinct architecture and jelly-roll topology

Superfamilies:

  1. RmlC-like cupins [51182] (20) picpic
  2. Clavaminate synthase-like [51197] (12) picpic
    Iron and ketoglutarate-dependent enzymes; elaborated version of this common fold
  3. cAMP-binding domain-like [51206] (3) picpic
  4. Regulatory protein AraC [51215] (1) picpic
  5. Thiamin pyrophosphokinase, substrate-binding domain [63862] (1) picpic
  6. Calcium ATPase, transduction domain A [81653] (1) picpic
    a distorted variant of double-helix
  7. TRAP-like [51219] (2) picpic
    shorter variant of double-helix; assembles in large ring-like structures containing from 9 to 11 domains
