Superfamilies:

1. Ribbon-helix-helix [47598] (11)
   formerly Met repressor-like; dimeric proteins; the N-termini form a small beta-sheet ribbon
   uperfamily
   1. Arc/Mnt-like phage repressors [47599] (2)
   2. CopG-like [100970] (5)
      similar to the phage repressor family
   3. Omega transcriptional repressor [100971] (1)
      plasmid-encoded, similar to the phage repressor family
   4. Met repressor, MetJ (MetR) [100972] (1)
   5. NE0241-like [140544] (1)
      contains extra C-terminal long helix; currently consists of an orphan protein
   6. SeqA N-terminal domain-like [140547] (1)
      N-terminal part of Pfam 03925
   7. Trafficking protein A-like [140550] (1)
   8. VCA0319-like [140553] (1)
      COG4453; extended and extra C-terminal helices; potential component of the bi-partite system also including an acetyltransferase
   9. VirC2-like [158482] (1)
      Pfam 07181; duplicated ribbon-helix-helix motif; fold forms a trefoil knot
   10. PutA pre-N-terminal region-like [158485] (1)
       in PutA it forms a separate ribbon-helix-helix domain connected to the N-terminal enzymatic domain by a flexible linker
   11. MJ0366-like [158488] (1)
       PfamB 022101; duplicated ribbon-helix-helix motif; forms trefoil knot; predicted DNA binding
