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