description: This entry represents the DNA delivery proteins P32 and P34 that are found in the virion
  membrane. It is responsible for DNA delivery and viral infectivity [[cite:PUB00109678],[cite:PUB00046003]].
  It is also required for DNA injection in the membrane transformation event. In Enterobacteria phage
  PRD1 virions, which are composed of a tail-less icosahedral capsid, an inner protein-lipid membrane,
  and a dsDNA genome which is located inside the lipid vesicle; the DNA is packaged into a preformed procapsid.
  The internal membrane plays an active role in DNA delivery to the host cell by forming a tubular structure
  used for injecting the DNA into the host cytoplasm.
