Lineage for Superfamily g.37.1: beta-beta-alpha zinc fingers

  1. Root: SCOP 1.75
  2. 888632Class g: Small proteins [56992] (90 folds)
  3. 892092Fold g.37: beta-beta-alpha zinc fingers [57666] (1 superfamily)
    simple fold, consisting of the N-terminal beta-hairpin and C-terminal alpha-helical region; each part provides two zinc-coordinating residues with the observed sequences including C2H2, C2HC and CHHC
  4. 892093Superfamily g.37.1: beta-beta-alpha zinc fingers [57667] (7 families) (S)


  1. 892094g.37.1.1: Classic zinc finger, C2H2 [57668] (30 proteins)
  2. 892320g.37.1.2: C2HC finger [57697] (3 proteins)
  3. 892334g.37.1.3: Plant C2H2 finger (QALGGH zinc finger) [90198] (1 protein)
  4. 892338g.37.1.4: HkH motif-containing C2H2 finger [111436] (4 proteins)
    putative dsRNA-specific zinc finger with a helix-kink-helix (HkH) motif; the kink results from the incompatibility of the cation-coordinating H-x5-H motif with a regular alpha-helix and contributes to RNA recognition
  5. 892352g.37.1.5: variant C2H2 finger [118273] (1 protein)
    contains extra C-terminal, alpha-helical subdomain
  6. 892356g.37.1.6: BED zinc finger [144157] (1 protein)
    Pfam PF02892; contains extra N-terminal and C-terminal helices bundled together with the core helix
  7. 892360g.37.1.7: CHHC finger [161158] (1 protein)
