  3. 1996372Fold a.43: Ribbon-helix-helix [47597] (1 superfamily)
    core: 4 helices; array of 2 hairpins, opened
  4. 1996373Superfamily a.43.1: Ribbon-helix-helix [47598] (12 families) (S)
    formerly Met repressor-like; dimeric proteins; the N-termini form a small beta-sheet ribbon


  1. 1996374a.43.1.1: Arc/Mnt-like phage repressors [47599] (2 protein domains)
  2. 1996415a.43.1.3: CopG-like [100970] (4 protein domains)
    similar to the phage repressor family
  3. 1996469a.43.1.4: Omega transcriptional repressor [100971] (2 protein domains)
    plasmid-encoded, similar to the phage repressor family
    automatically mapped to Pfam PF07764
  4. 1996488a.43.1.5: Met repressor, MetJ (MetR) [100972] (1 protein)
    automatically mapped to Pfam PF01340
  5. 1996521a.43.1.6: NE0241-like [140544] (1 protein)
    contains extra C-terminal long helix; currently consists of an orphan protein
  6. 1996525a.43.1.7: SeqA N-terminal domain-like [140547] (1 protein)
    N-terminal part of Pfam PF03925
  7. 1996532a.43.1.8: Trafficking protein A-like [140550] (1 protein)
  8. 1996543a.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
