HNH/Endo VII superfamily nuclease toxin with a HHH motif
A predicted toxin of the HNH/Endonuclease VII fold present in bacterial polymorphic toxin systems with characteriztic conserved s[GD]xxR and HHH motifs. In bacterial polymorphic toxin systems, the toxin is exported by the type 2, type 5, type 6, type 7 or Photorhabdus virulence cassette (PVC)-type secretion system.
