description: Holin_2-3 is a putative holins with 2 or 3 transmembrane segments. It consists of many proteobacterial
  proteins ranging in size from about 70 aas to 120 aas. They have 2 or 3 predicted TMSs. Although some
  are annotated as phage proteins or holins, none appears to be functionally characterised.
