Given the presumed sharing of debris generated from meteorite impacts amongst the early planets, origins of D. radiodurans might even be accidentally common between Mars and Earth. A Microbial Biorealm page on the genus Deinococcus radiodurans, Bacteria; Deinococcus-Thermus; Deinococci; Deinococcales; Deinococcaceae; Deinococcus, Deinococcus radiodurans was first discovered in 1956 in a can of ground meat that had been treated with large doses of radiation to remove all hazardous bacteria from the product. Structure of D. radiodurans SSB. [4], Yet another interesting point about this species is that it is able to quickly and accurately repair double-strand breaks in its DNA without the normal RecBCD enzyme that is present in other bacteria. It is often cultured in the lab from the feces of animals, such as elephants. (A) Schematic diagram of D. radiodurans SSB primary structure.Two OB folds are present in each D. radiodurans SSB monomer: one is N-terminal (blue, residues 1–108), and one is C-terminal (red, residues 129–233).

Deinococcus marmoris Phylogeny.jpg 666 × 832; 86 KB. Fig. Genetic mutations have major consequences for mankind. There is no current findings that suggest that D. radiodurans significantly interacts with other organisms in nature. The name, ‘Deinococcus radiodurans,’ has been derived from the Greek language which literally translates to ‘strange-berry.’ It is a Gram-positive, nonpathogenic bacterium with an average cell diameter of 1 μm. This organism is interesting because of its extreme resistance to DNA damage induced by ionizing radiation ().It exhibits detectable survival after irradiation of 15,000 Gy and grows continuously at 60 Gy/h ().The unusual radiation resistance of D. radiodurans … Deinococcus–Thermus is a phylum of bacteria that are highly resistant to environmental hazards, also known as extremophiles. Truepera radiovictrixDSM 17093 9. And how is it that it can also withstand extreme radiation despite the fact that radiation does not occur in the natural world? Deinococcus radiodurans is an extremophilic bacterium, one of the most radioresistant organisms known. 1960 ›ATCC 13939 ›CCUG 27074 ›CIP 104750 ›DSM 20539 More » ›Deinococcus radiidurans ›Deinococcus radiodurans (ex Raj et al.

The bacteria Radiodurans shrugs off radiation better than any cockroach around. Among these extremophiles, Deinococcus radiodurans is an important organism because it can able to survive in high radiation, ionizing and non-ionizing exposure (Slade and Radman, 2011). 5. Genome sequence of the radioresistant bacterium Deinococcus radiodurans R1. Servinsky MD, Julin DA. GenBank. Deinococcus radiodurans — The Consumate Survivor. Deinococcus radiodurans is bolded in black next to Thermus thermophilus showing they have a common ancestor. The name Deinococcus radiodurans derives from the Ancient Greek δεινός (deinos) and κόκκος (kokkos) meaning "terrible grain/berry" and the Latin radius and durare, meaning "radiation surviving".The species was formerly called Micrococcus radiodurans.As a consequence of its hardiness, it … Deinococcus radiodurans was first discovered in 1956 in a can of ground meat that had been treated with large doses of radiation to remove all hazardous bacteria from the product. The bacterium, whose name means 'strange berry that withstands radiation,' is the most radiation-resistant organism known. Since it is thought that the radiation resistance of D. radiodurans relies heavily on the cell's specialized proteins and cell structure, much research has been done to elucidate the structures of these proteins. 2. Since then, D. radiodurans has been discovered in a wide variety of habitats.The mechanisms of survival allow it to withstand long periods of desiccation. Nucleic Acids Res 2000 Jan 1;28(1):15-18. However, it is known that multiple copies of each gene are found on all the chromosomes and plasmids, which most likely contributes to its amazing repair capabilities associated with its radiation resistance. These numerous soil dwellings have led many to classify D. radiodurans as a soil bacteria. Deinococcus radiodurans. Currently, the organisms that are used for chemical and biological clean-up are not resistant to radiation. The bacteria Radiodurans shrugs off radiation better than any cockroach around. This significant finding suggests that this RecD-like protein in D. radiodurans is an important part of the repair system it uses. "By nature, it is selected to survive radiation damage very well," D. radiodurans can withstand without loss of viability a dosage that is 3,000 … 2005 Mar;36(2):200-3. [2], The genome of D. radiodurans consists of four major parts. It is able to cope without air, water and food, and can withstand very high doses of radiation which would kill a human.

The microbes can deal with extreme cold, lack of water, vacuums and high acidity. Deinococcus radiodurans is capable of surviving 15,000 grays (Gy) of ionizing radiation, whereas doses below 10 Gy are lethal to all other organisms (1, 2).The bacterium's phenomenal radioresistance derives from its ability to accurately mend hundreds of double-strand DNA breaks ().This mending is unlikely to occur … Given the presumed sharing of debris generated from meteorite impacts amongst the early planets, origins of D. radiodurans might even be accidentally common between Mars and Earth. It has been known to withstand radiation levels of up to 1,000 times that which would kill a normal human, living up to its latin name, "strange little berry that withstands radiation." So far this research has not been completely successful, however it has as the team put it "provided the foundations for further studies and applications of the recombinant Mn-SOD."[6].

One such protein whose structure in this bacteria was recently discovered is thioredoxin reductase. [2], D. radiodurans has been found in a wide variety of environments which therefore make its "natural" habitat difficult to define. For example, research into the micro-organism could lead to medical applications to protect people better against the terrible results of radiation poisoning. Deinococus bacteria are ubiquitous in nature and have been isolated from various … Because D. radiodurans does not actually degrade the toxins, it will be used in conjuction with microbes that can degrade.
