DNA delivery protein, P32/P34 (IPR020085)

Short name: DNA_delivery_prot_P32/34

Family relationships



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 [PMID: 12453208]. 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.
