  3. 1089029Fold a.43: Ribbon-helix-helix [47597] (1 superfamily)
    core: 4 helices; array of 2 hairpins, opened
  4. 1089030Superfamily a.43.1: Ribbon-helix-helix [47598] (11 families) (S)
    formerly Met repressor-like; dimeric proteins; the N-termini form a small beta-sheet ribbon

Families:

  2. 1089073a.43.1.3: CopG-like [100970] (4 proteins)
    similar to the phage repressor family
  3. 1089128a.43.1.4: Omega transcriptional repressor [100971] (2 proteins)
    plasmid-encoded, similar to the phage repressor family
  4. 1089147a.43.1.5: Met repressor, MetJ (MetR) [100972] (1 protein)
  5. 1089180a.43.1.6: NE0241-like [140544] (1 protein)
    contains extra C-terminal long helix; currently consists of an orphan protein
  6. 1089184a.43.1.7: SeqA N-terminal domain-like [140547] (1 protein)
    N-terminal part of Pfam PF03925
  7. 1089191a.43.1.8: Trafficking protein A-like [140550] (1 protein)
  8. 1089202a.43.1.9: VCA0319-like [140553] (1 protein)
    COG4453; extended and extra C-terminal helices; potential component of the bi-partite system also including an acetyltransferase
  9. 1089207a.43.1.10: VirC2-like [158482] (1 protein)
    Pfam PF07181; duplicated ribbon-helix-helix motif; fold forms a trefoil knot
