''Globuloviridae'' is a family of hyperthermophilic

archaeal viruses An archaeal virus is a virus that infects and replicates in archaea, a domain of unicellular, prokaryotic organisms. Archaeal viruses, like their hosts, are found worldwide, including in extreme environments inhospitable to most life such as acid ...

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. ODD

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.
