Tevenvirinae
Tevenvirinae is a subfamily of viruses in the order Caudovirales, in the family Myoviridae. Bacteria and archaea serve as natural hosts. There are currently 54 species in this subfamily, most included in 11 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]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| T4virus | Head-Tail | T=13 Q=21 | Non-enveloped | Linear | Monopartite |
| Schizot4virus | Head-Tail | T=13 Q=21 | Non-enveloped | Linear | Monopartite |
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]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| T4virus | Bacteria: gram negative | None | Injection | Lysis | Cytoplasm | Cytoplasm | Passive diffusion |
| Schizot4virus | Bacteria | None | Injection | Lysis | Cytoplasm | Cytoplasm | Passive diffusion |
