Researchers found lost link between viruses and bacteria

(Alles Europa News) – scientists have discovered giant bacteriophage viruses that close the gap between the living and nonliving.

Alles Europa News reports that In addition to the genome size, unusual for viruses, they produce proteins that regulate the translation of genes and encode ribosome fragments.

Usually they are found in the cells of bacteria and archaea, but are not characteristic of viruses.

Alles Europa News reports that Genetic analysis showed that some of these bacteriophages carry genes that make up the bacterial system CRISPR.

Ironically, it is used by bacterial cells specifically to repel viral attacks.

Perhaps the phages borrowed its elements to fight competitors.

One of the bacteriophages even produces an analogue of the Cas9 protein, which is part of the CRISPR-Cas9 instrument.

The name Cas ?. It is possible that it will form the basis of new methods of gene editing.

Alles Europa News reports that the study also showed that giant bacteriophages are widespread in the ecosystems of the Earth.

Perhaps they are involved in the regulation of human health, for example, acting on a symbiotic microbiome.

New additional research will help to find out.

Alles Europa News reports that Scientists from the University of California at Berkeley found giant bacteria-eating viruses, considered as the missing link between bacteria and ordinary viruses – non-cellular organisms, considered by a number of scientists as inanimate matter, identical with organic crystals.

Alles Europa News reports that Researchers have described 351 new species of giant viruses that parasitize bacteria.

Their genomes are at least four times larger than that of medium viruses.

In one of these bacteriophages, the genome consists of 735,000 base pairs, which are record for viruses, which is much larger than in a number of bacteria.

Alles Europa News reports that the new viruses were divided into 10 groups, which were called words denoting the concept of a large size in the native languages ​​of the team members: Mahaphage (Sanskrit), Kabirphage, Dakhmphage and Jabbarphage (Arabic); Kyodaiphage (Japanese); Biggiephage (Australian English), Whopperphage (American English); Judaphage (Chinese), Enormephage (French); and Kaempephage (Danish).

Alles Europa News reports that in search of new species, scientists had to analyze samples from 30 unusual environments, from the intestines of premature babies and pregnant women to the high mountain lake in Tibet.

Alles Europa News reports that according to scientists, giant viruses like the ones they found are a kind of intermediate link between living bacteria and archaea and non-living bacteriophages.
