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]

Structure[edit]

Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm.[1][2]

Genome organization of Pyrobaculum spherical virus (PSV) showing location, sizes and direction of putative genes.

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]
