Sulfolobus acidocaldarius, strain B12, which harbours a double‐stranded DNA species both as a plasmid and in a linear form, which is integrated at a specific site of the chromosome, produces virus‐like particles upon u.v. irradiation. These particles contain the same circular DNA and a number of coat proteins and are probably surrounded by a lipid membrane. They are lemon shaped, 100 x 60 nm in size and carry tail structures at one pole. The host cell recovers and remains lysogenic after virus… Expand
Isolate B12, which harbours a virus-like element, represents a new species of the archaebacterial genus Sulfolobus, Sulfolobus shibatae, sp. nov.
TLDR
Although the results generally demonstrate a similarity to S. solfataricus, DNA-DNA hybridisation and 16S rRNA sequence data indicate that isolate B12 in fact represents a distinct species. Expand
SNDV, a novel virus of the extremely thermophilic and acidophilic archaeon Sulfolobus.
TLDR
A novel virus, SNDV (Sulfolobus neozealandicus droplet-shaped virus), of the crenarchaeotal archaeon Sulfol Obus is described and proposed to assign it to a novel virus family termed Guttaviridae, which is postulate a virus-encoded methylase that is active on hemimethylated DNA. Expand
Cysteine usage in Sulfolobus spindle-shaped virus 1 and extension to hyperthermophilic viruses in general.
TLDR
Biochemical, proteomic and structural studies reveal a monomeric intracellular protein that adopts a winged helix DNA binding fold that contains an intrachain disulfide bond, prompting analysis of cysteine usage in this and other hyperthermophilic viral genomes. Expand
Provirus Induction in Hyperthermophilic Archaea: Characterization of Aeropyrum pernix Spindle-Shaped Virus 1 and Aeropyrum pernix Ovoid Virus 1
TLDR
By in silico analysis, two putative proviruses in the genome of the hyperthermophilic archaeon Aeropyrum pernix are identified and under special conditions of A.pernix growth, they were able to induce their replication and are proposed to classify into the family Guttaviridae. Expand
Spindle Shaped Virus (SSV) : Mutants and Their Infectivity
TLDR
The lemon shaped/spindle-shaped fuselloviruses (SSV) that infect Sulfolobus solfataricus is quite morphologically different from almost all other viruses, and its genomes and structures have adapted to withstand such harsh conditions. Expand
Sulfolobus Spindle-Shaped Virus 1 Contains Glycosylated Capsid Proteins, a Cellular Chromatin Protein, and Host-Derived Lipids
TLDR
An extensive biochemical characterization of highly purified SSV1 virions is conducted and four virus-encoded structural proteins, VP1 to VP4, as well as one DNA-binding protein of cellular origin are identified, improving the understanding of the adaptation of viruses with unusual morphotypes to extreme environmental conditions.

Spindle Shaped Virus: Mutants and Their I nfectivity
TLDR
The lemon shaped/spindle-shaped fuselloviruses (SSV) that infect Sulfolobus solfataricus is quite morphologically different from almost all other viruses, and its genomes and structures have adapted to withstand such harsh conditions. Expand
Isolation and characterization of novel temperate virus Aeropyrum globular virus 1 infecting hyperthermophilic archaeon Aeropyrum
TLDR
It is suggested that Aeropyrum globular virus 1 can escape from the host defense system and propagate under stressful conditions for the host by establishing an unstable carrier state in the growing host. Expand
A Novel Type of Polyhedral Viruses Infecting Hyperthermophilic Archaea
TLDR
A new virus of hyperthermophilic archaea, Sulfolobus polyhedral virus 1 (SPV1), is described, which condenses its circular double-stranded DNA genome in a manner not previously observed for other known viruses. Expand
