Structural insights into the mechanism of archaellar rotational switching

Nature Communications, 2022
Signal transduction via phosphorylated CheY is conserved in bacteria and archaea. In this study, the authors employ structural biochemistry combined with cell biology to delineate the mechanism of CheY recognition by the adaptor protein CheF.

Structure and cell biology of archaeal virus STIV. [PDF]

Curr Opin Virol, 2012
Recent investigations of archaeal viruses have revealed novel features of their structures and life cycles when compared to eukaryotic and bacterial viruses, yet there are structure-based unifying themes suggesting common ancestral relationships among dsDNA viruses in the three kingdoms of life.

Influence of N-Glycosylation on Virus–Host Interactions in Halorubrum lacusprofundi

Viruses, 2023
N-glycosylation is a post-translational modification of proteins that occurs across all three domains of life. In Archaea, N-glycosylation is crucial for cell stability and motility, but importantly also has significant implications for virus–host ...

Insights into the spool-like architecture and infection strategy of an enveloped archaeal virus. [PDF]

Sci Adv
Archaeal viruses are well known for their diverse morphologies and extreme stability. Here, we used cryo–electron tomography to analyze the structure of Sulfolobus ellipsoid virus 1 (SEV1), an archaeal virus with an ellipsoidal shape and a lipid envelope, and its infection strategy.

The Viral Susceptibility of the Haloferax Species

Viruses, 2022
Viruses can infect members of all three domains of life. However, little is known about viruses infecting archaea and the mechanisms that determine their host interactions are poorly understood.

vConTACT: an iVirus tool to classify double-stranded DNA viruses that infect Archaea and Bacteria [PDF]

PeerJ, 2017
Taxonomic classification of archaeal and bacterial viruses is challenging, yet also fundamental for developing a predictive understanding of microbial ecosystems.

Isolation of archaeal viruses with lipid membrane from Tengchong acidic hot springs

Frontiers in Microbiology, 2023
Archaeal viruses are one of the most mysterious parts of the virosphere because of their diverse morphologies and unique genome contents. The crenarchaeal viruses are commonly found in high temperature and acidic hot springs, and the number of identified

Fidelity in Archaeal Information Processing [PDF]

, 2010
A key element during the flow of genetic information in living systems is fidelity. The accuracy of DNA replication influences the genome size as well as the rate of genome evolution.

DNA ejection from an archaeal virus--a single-molecule approach. [PDF]

Biophys J, 2013
The translocation of genetic material from the viral capsid to the cell is an essential part of the viral infection process. Whether the energetics of this process is driven by the energy stored within the confined nucleic acid or cellular processes pull the genome into the cell has been the subject of discussion.
