Group: Group I (dsDNA)
Order: Caudovirales
Family: Myoviridae
Subfamily: Tevenvirinae
Genera

Tevenvirinae is a subfamily of viruses in the order Caudovirales, in the family Myoviridae. Bacteria and archaea serve as natural hosts. There are currently 43 species in this subfamily, most included in 8 genera.[1][2]

Structure

Viruses in Tevenvirinae are non-enveloped, with head-tail geometries. These viruses are about 70 nm wide and 140 nm long. Genomes are linear, around 170-245kb in length. The genome codes for 300 to 415 proteins.[1]

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. The virus exits the host cell by lysis, and holin/endolysin/spanin proteins. Bacteria and archaea serve as the natural host. Transmission routes are passive diffusion. [1]
