ICTV Virus Taxonomy Profile: Simuloviridae 2023

J Gen Virol. 2023 Apr;104(4). doi: 10.1099/jgv.0.001841.

Abstract

The family Simuloviridae includes tailless icosahedral viruses with an internal lipid membrane. The capsid is constructed from two major capsid proteins, both with a single jelly-roll fold. The genome is a circular dsDNA molecule of 16-19 kb. All members infect halophilic archaea in the class Halobacteria (phylum Euryarchaeota) and are temperate viruses, their proviruses residing in host cells as extrachromosomal episomes. Once the lytic life cycle is triggered, production of virions causes cell lysis. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Simuloviridae, which is available at ictv.global/report/simuloviridae.
