Clavaviridae
''Clavaviridae'' is a family of double-stranded viruses that infect archaea. This family was first described by the team led by D. Prangishvili in 2010. There is one genus in this family (''Clavavirus''). Within this genus, a single species has been described to date: '' Aeropyrum pernix bacilliform virus 1'' (APBV1). The name is derived from the Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... word ''clava'' meaning stick. Virology The virons are bacilliform in shape and 143 nanometers (nm) in length and 15.8 nm in diameter. One end is pointed and the other is rounded. The structure of the APBV1 virion has been solved by cryo-electron microscopy to near-atomic resolution, revealing how the helical particle is built from an alpha-helical major capsid protein with ...

David Prangishvili
David Prangishvili (born 1948) is a virologist, Professor at the Pasteur Institute of Paris, and foremost authority on viruses infecting Archaea. Biography David Prangishvili gained a Master of Science degree in 1971 at Tbilisi State University, Georgia, and a PhD (1977) and Habilitation (1989) from Institute of Molecular Biology of the USSR Academy of Sciences, Moscow. He pioneered research on Archaea, the third domain of life, in the USSR and in 1986-1991 was a head of the department of Molecular Biology of Archaea at the Georgian Academy of Sciences, Tbilisi. In 1991-2004 he has worked in Germany, at Max-Planck Institute for Biochemistry and at Regensburg University. Since 2004 he is working at the Pasteur Institute of Paris. David Prangishvili received a prize of Council of Ministers of the USSR for Excellence in Science and Technology in 1979. David Prangishvili has been elected Member of thAcademia Europaea(2018), Member of thEuropean Academy of Microbiology(2015), For ...

Double-stranded DNA Viruses
A DNA virus is a virus that has a genome made of deoxyribonucleic acid (DNA) that is replicated by a DNA polymerase. They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses. dsDNA viruses primarily belong to two realms: ''Duplodnaviria'' and ''Varidnaviria'', and ssDNA viruses are almost exclusively assigned to the realm ''Monodnaviria'', which also includes some dsDNA viruses. Additionally, many DNA viruses are unassigned to higher taxa. Reverse transcribing viruses, which have a DNA genome that is replicated through an RNA intermediate by a reverse transcriptase, are classified into the kingdom '' Pararnavirae'' in the realm '' Riboviria''. DNA viruses are ubiquitous worldwide, especially in marine environments where they form an important part of marine ecosystems, and infect both prokaryotes and eukaryotes. The ...

Archaea
Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of '' Haloquadratum walsbyi''. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes invo ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...
