Enterobacteria phage PsP3

Enterobacteria phage PsP3 is a virus of the family Myoviridae, genus P2likevirus.

As a member of the group I of the Baltimore classification, Enterobacteria phage PsP3 is a dsDNA viruses. All the Myoviridae family members share a nonenveloped morphology consisting of a head and a tail separated by a neck. Its genome is linear. The propagation of the virions includes the attaching to a host cell (a bacterium, as Enterobacteria phage PsP3 is a bacteriophage) and the injection of the double stranded DNA; the host transcribes and translates it to manufacture new particles. To replicate its genetic content requires host cell DNA polymerases and, hence, the process is highly dependent on the cell cycle.
