The thermo‐ and acido‐stable ORF‐99 from the archaeal virus AFV1 [PDF]

Protein Science, 2009
AbstractAcidianus Filamentous Virus 1 (AFV1), isolated from acidic hot springs, is an enveloped lipid‐containing archaeal filamentous virus with a linear double‐stranded DNA genome. It infects Acidianus, which is a hyperthermostable archaea growing at 85°C and acidic pHs, below pH 3.

The Molecular Mechanism of Cellular Attachment for an Archaeal Virus

The FASEB Journal, 2020
Sulfolobus turreted icosahedral virus (STIV) is a model archaeal virus with a pseudo‐T=31 icosahedral virion with a mass of ~64 mega‐Daltons. Although STIV employs pyramidal lysis structures to exit the host, knowledge of the viral entry process is lacking.

Differentiation and Structure in Sulfolobus islandicus Rod-Shaped Virus Populations

Viruses, 2017
In the past decade, molecular surveys of viral diversity have revealed that viruses are the most diverse and abundant biological entities on Earth. In culture, however, most viral isolates that infect microbes are represented by a few variants isolated ...

HCIV-1 and Other Tailless Icosahedral Internal Membrane-Containing Viruses of the Family Sphaerolipoviridae

Viruses, 2017
Members of the virus family Sphaerolipoviridae include both archaeal viruses and bacteriophages that possess a tailless icosahedral capsid with an internal membrane.

Insights into a Viral Lytic Pathway from an Archaeal Virus-Host System [PDF]

Journal of Virology, 2013
ABSTRACT Archaeal host cells infected by Sulfolobus turreted icosahedral virus (STIV) and Sulfolobus islandicus rod-shaped virus 2 (SIRV2) produce unusual pyramid-like structures on the cell surface prior to virus-induced cell lysis.

DNA-Interacting Characteristics of the Archaeal Rudiviral Protein SIRV2_Gp1

Viruses, 2017
Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored.

Revisiting evolutionary trajectories and the organization of the Pleolipoviridae family.

PLoS Genetics, 2023
Archaeal pleomorphic viruses belonging to the Pleolipoviridae family represent an enigmatic group as they exhibit unique genomic features and are thought to have evolved through recombination with different archaeal plasmids.

Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail. [PDF]

Sci Adv
While archaeal viruses show a stunning diversity of morphologies, many bear a notable resemblance to tailed bacterial phages. This raises fundamental questions: Do all tailed viruses share a common origin and do they infect their hosts in similar ways ...

Protein-protein interactions leading to recruitment of the host DNA sliding clamp by the hyperthermophilic Sulfolobus islandicus rod- shaped virus 2

, 2014
Viruses infecting hyperthermophilic archaea typically do not encode DNA polymerases, raising questions regarding their genome replication. Here, using a yeast two-hybrid approach, we have assessed interactions between proteins of Sulfolobus islandicus ...

A Survey of Protein Structures from Archaeal Viruses

Life, 2013
Viruses that infect the third domain of life, Archaea, are a newly emerging field of interest. To date, all characterized archaeal viruses infect archaea that thrive in extreme conditions, such as halophilic, hyperthermophilic, and methanogenic ...
