Bppunalikevirus

Bppunalikevirus is a genus of viruses in the order Caudovirales, in the family Podoviridae. Bacteria serve as natural hosts, and currently contains only two species. This genus of temperate phages is named after its first sequenced member, Bordetella phage BPP-1, which also serves as its type species.[1][2]

Structure

Viruses in Bppunalikevirus are non-enveloped, with icosahedral and Head-tail geometries, and T=7 symmetry. The diameter is around 67 nm. Genomes are linear, around 42kb in length, and usually encodes about 50 proteins. The Bordetella phages of this genus contains an RNA-directed DNA polymerase which plays a role in tropism.[1][3] [4]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. Dna templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
