    core: 4 helices; folded leaf, closed

Superfamilies:

    link to SUPERFAMILY database - Superfamily
    1. POU-specific domain [47414] (3) picpic
    2. Phage repressors [47419] (7) picpic
      consists of different sequence families of HTH repressors of phage origins
    3. SinR domain-like [47432] (8) picpic
    4. Cyanase N-terminal domain [47435] (1) picpic
      probably does not bind to DNA
    5. GalR/LacI-like bacterial regulator [47438] (4) picpic
      lacks the first helix of canonical fold
      3 helices; bundle, partly opened, right-handed twist
    6. YdiL-like [109813] (2) picpic
      contains extra C-terminal all-alpha dimerization subdomain; the dimer may bind DNA
    7. CUT domain [116891] (4) picpic
      Pfam 02376
    8. Probable transcriptional regulator VC1968, N-terminal domain [116898] (1) picpic
    9. Bacteriophage CII protein [140520] (1) picpic
      Pfam 05269; a compact helix-swapped dimer of the canonical fold; includes the extra C-terminal teramerisation region (alpha-helix); in the tetramer-DNA complex only two of the four HTH motifs interact with DNA
    10. NE0471 C-terminal domain-like [140523] (1) picpic
    11. PrgX N-terminal domain-like [140526] (1) picpic
      Part of Pfam 01381
    12. EDF1-like [140529] (1) picpic
      part of Pfam 01381
    13. NE1354 [140532] (2) picpic
      contains extra C-terminal dimerisation arm (beta-strand)
