Globuloviridae

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.

Taxonomy
The family contains one genus which contains four species:
 * Alphaglobulovirus
 * Alphaglobulovirus PSV
 * Alphaglobulovirus PSV1
 * Alphaglobulovirus TSPV1
 * Alphaglobulovirus TTSV1

Structure
Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm.

Genomes are linear dsDNA and non-segmented, around 20–30kb in length.

Life cycle
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.
