One of the most prominent features of archaea is the extraordinary diversity of their DNA
viruses. Many archaeal viruses differ substantially in morphology from bacterial and …

Enzymes from extremely thermophilic microorganisms have been of technological interest
for some time because of their ability to catalyze reactions of industrial significance at …

Recent discoveries of new large DNA viruses reveal high diversity in their morphologies,
genetic repertoires, and replication strategies. Here, we report the novel features of …

Prokaryotes, bacteria and archaea, are the most abundant cellular organisms among those
sharing the planet Earth with human beings (among others). However, numerous ecological …

Viruses employ a range of strategies to counteract the prokaryotic adaptive immune system,
clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins …

Argonaute (Ago) proteins are widespread nucleic-acid-guided enzymes that recognize
targets through complementary base pairing. Although, in eukaryotes, Agos are involved in …

This review presents a personal account of research on archaeal viruses and describes
many new viral species and families, demonstrating that viruses of Archaea constitute a …

Central to the disparate adaptive immune systems of archaea and bacteria are clustered
regularly interspaced short palindromic repeats (CRISPR). The spacer regions derive from …

Viruses are parasitic organisms that live in infected cells and produce virions to disseminate
their genes. Most viral proteins have no homologues in modern cells, in contradiction with …

The genomes of two Sulfolobus islandicus strains obtained from Icelandic solfataras were
sequenced and analyzed. Strain REY15A is a host for a versatile genetic toolbox. It exhibits …
