Superfamily: beta-beta-alpha zinc fingers

link to SUPERFAMILY database - Superfamily

Lineage:

  1. Root: scop
  2. Class: Small proteins [56992]
    Usually dominated by metal ligand, heme, and/or disulfide bridges
  3. Fold: beta-beta-alpha zinc fingers [57666]
    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. Superfamily: beta-beta-alpha zinc fingers [57667]
    link to SUPERFAMILY database - Superfamily

Families:

  1. Classic zinc finger, C2H2 [57668] (30) picpic
  2. Plant C2H2 finger (QALGGH zinc finger) [90198] (1) picpic
  3. C2HC finger [57697] (3) picpic
  4. HkH motif-containing C2H2 finger [111436] (4) picpic
    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. CHHC finger [161158] (1) picpic
  6. variant C2H2 finger [118273] (1) picpic
    contains extra C-terminal, alpha-helical subdomain
  7. BED zinc finger [144157] (1) picpic
    Pfam 02892; contains extra N-terminal and C-terminal helices bundled together with the core helix
