Staphylococcus virus G1

As a member of the group I of the Baltimore classification, Staphylococcus virus G1 is a dsDNA viruses. All the family Herelleviridae 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 Staphylococcus virus G1 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.[3]

The phage contains a genome of 138,715 base pairs with a 30.4% of GC content and 214 predicted genes; this means that the 88.5% of the DNA is coding open reading frames, and therefore the gene density (the number of genes per kilobase) is 1.54.[4]
