Pandoravirus is bridges the viral and cell groups

Two types of giant virus discovered by a team of scientists and shows a number of anomalies (in contrast to other viruses that are generally small and simple). The first giant virus (Pandoravirus salinus) found in coastal Chile, while Pandoravirus dulcis virus taken from freshwater lake in Melbourne, Australia.

Detailed analysis in the Science journal suggests that both types of Pandoravirus was almost nothing in common with a number of giant viruses have ever been identified before.
Giant viruses are some of the most complex viruses on Earth. Containing over a thousand genes and with a size that's far larger than typical viruses, they may just be the missing link between viruses and cells. Now, scientists have discovered two new giant viruses, which could lead to more information about the evolutionary history of cells. Pandoravirus salinus observed under the electron microscope.

For example, Pandoravirus salinus only 6 percent of the encode proteins similar to those already identified in other viral or cellular organisms. The number of Pandoravirus salinus genomes is thousands of genes suggests that the virus may have a more complex structure than a eukaryotic cell, such as protozoa cells, plant cells, and animal cells. "Just for comparison, the virus such as influenza and AIDS, each only has 10 genes," the researchers wrote last week.

Pandoravirus also has unusual features. They do not have the genes to build several types of proteins, such as capsid proteins, which are the basic building blocks of traditional viruses.

The findings are no less important is the Pandoravirus salinus proteome analysis which shows that the process of making proteins on the virus is consistent with that predicted by the genome sequence of the virus. "They use the universal genetic code shared by all living things on this planet," said the research team. "Pandoravirus is a connecting link that bridges the viral and cell groups." *** [EKA | FROM VARIOUS SOURCES | SCIENCEDAILY | MAHARDIKA SATRIA HADI | KORAN TEMPO 4381]
