Viruses of archaea represent one of the most enigmatic parts of the virosphere. Most of the
characterized archaeal viruses infect extremophilic hosts and display remarkable diversity of …

Research on archaeal extrachromosomal genetic elements (ECEs) has progressed rapidly
in the past decade. To date, over 60 archaeal viruses and 60 plasmids have been isolated …

The Archaea—and their viruses—remain the most enigmatic of life's three domains. Once
thought to inhabit only extreme environments, archaea are now known to inhabit diverse …

Tyrosine family site‐specific recombinases (YRs), named after the active site tyrosine
nucleophile they utilize for DNA strand breakage, are widely distributed among prokaryotes …

Genomes of halophilic archaea typically contain multiple loci of integrated mobile genetic
elements (MGEs). Despite the abundance of these elements, however, mechanisms …

Saccharolobus spindle-shaped virus 1 (SSV1) was one of the first viruses identified in the
archaeal kingdom. Originally isolated from a Japanese species of Saccharolobus back in …

Fuselloviruses, also known as Sulfolobus Spindle-shaped viruses (SSVs), are “lemon”-or
“spindle”-shaped double-stranded DNA viruses. Among them, SSV1, SSV2 and the satellite …

The integration of mobile genetic elements into their host chromosome influences the
immediate fate of cellular organisms and gradually shapes their evolution. Site-specific …

Viruses have played a central role in the evolution and ecology of cellular life since it first
arose. Investigations into viral molecular biology and ecological dynamics have propelled …

Tyrosine recombinases are conserved in the three kingdoms of life. Here we present the first
crystal structure of a full-length archaeal tyrosine recombinase, XerA from Pyrococcus …
