Turriviridae is a family of viruses; it contains only one genus, Alphaturrivirus. The archaea Sulfolobus solfataricus serve as natural hosts. There are two species in the genus Alphaturrivirus.[1][2]
Taxonomy
The genus contains the following species:[2]
Structure
Viruses in Turriviridae have icosahedral geometries, and T=31 symmetry. The diameter is around 74 nm. Genomes are circular.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Alphaturrivirus | Icosahedral | T=31 | Linear |
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. Sulfolobus solfataricus serves as the natural host. Transmission routes are passive diffusion.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Alphaturrivirus | Sulfolobus solfataricus | None | Injection | Budding | Cytoplasm | Cytoplasm | Passive Diffusion |
