Globuloviridae is a family of hyperthermophilic archaeal viruses. Crenarchaea of the genera Pyrobaculum and Thermoproteus (both in Thermoproteaceae) serve as natural hosts. There are four species in this family, assigned to a single genus, Alphaglobulovirus.[1][2][3]
Taxonomy
[edit]The family contains one genus which contains four species:[3]
- Alphaglobulovirus
Structure
[edit]Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm.[1][2]

Genomes are linear dsDNA and non-segmented, around 20–30kb in length.[1][2]
Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
---|---|---|---|---|---|
Alphaglobulovirus | Spherical | Enveloped | Linear | Monopartite |
Life cycle
[edit]Viral replication is cytoplasmic. DNA-templated transcription is the method of transcription. Pyrobaculum and Thermoproteus 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 |
---|---|---|---|---|---|---|---|
Alphaglobulovirus | Pyrobaculum and Thermoproteus archaea | None | Injection | Budding | Cytoplasm | Cytoplasm | Passive diffusion |
