Deinococcus radiodurans was exposed for 1 year outside the International Space Station within Tanpopo orbital mission to investigate microbial survival and space travel. Sleeper cell: Could Conan the Bacterium survive on Mars? ISSN 2045-2322 (online). DdrB stimulates single-stranded DNA annealing and facilitates RecA-independent DNA repair in Deinococcus radiodurans. Mol. Thus, it is not likely that DNA repair via NHEJ would engage two repetitive sequences separated by tens of kbp. [21] Due to the possibly important functions of these genes, the deletion of these genes was expected to have an adverse effect on growth and/or -survival. The importance of these nanoparticles relies on their medical applications as they have been demonstrated to exhibit activity against pathogenic bacteria, antifouling effects, and cytotoxicity to tumoral cells. Deinococcus radiodurans strain R1 was the first of the . Durable, low-linting, & available in white or blue. Just ask Scott Kelly, the American astronaut who spent a year on the International Space Station (ISS) in 2015. Rev. Formally, the RecA-independent DSB repair could also be carried out through the mechanism of non-homologous end-joining (NHEJ) which requires little or no homology between two ends exposed by DSB, and therefore, it is not specifically limited to any region of the genome18,19. Further eroding supportfor an active targeting mechanism, breakpoints and their surrounding sequences are very different from each other (Table S5). Deinococcus radiodurans has a unique quality in which it can repair both single- and double-stranded DNA. DNA Repair 9, 11511161 (2010). Rev. Genomic signatures, such as codon usage, can denote adaptive advantages. Rev. 4, 1. https://doi.org/10.1128/genomeA.00886-16 (2016). Through sequence analysis of the five rearranged D. radiodurans recA isolates, we tested probable adaptive and mechanistic hypotheses that might explain the recurrent deletions of the same chromosome II region. Lim, S., Jung, J.-H., Blanchard, L. & de Groot, A. 40, 701714 (2015). PLoS ONE 12, e0189261 (2017). You need to be comfortable and find the proper fit, VWR wants to help find the best pipette for you. Michel, B., Sinha, A. K. & Leach, D. R. F. Replication fork breakage and restart in Escherichiacoli. Li, H. Minimap and miniasm: Fast mapping and de novo assembly for noisy long sequences. U.S.A. 107, 21412146 (2010). Statistics for obtained subreads are shown in Table S2. D. radiodurans is the type species of this genus, and the best studied member. Avantor supports end-to-end fluid management solutions including Masterflex peristaltic pumps and aseptic fluid transfer solutions that are reliable and customer-centric, helping bioprocessing manufacturers meet their research and production goals. [13][14][15] A dose of 5,000Gy is estimated to introduce several hundred double-strand breaks (DSBs) into the organism's DNA (~0.005DSB/Gy/Mbp (haploid genome)). Daly, M. J. So, for returning subsurface soil samples from Mars for microbial characterization with a potentially "successful" mission like the European Rosalind Franklin rover, it would be necessary to target a relatively young impact crater to increase the chances of discovering dormant extremophile micro-organisms surviving in the dry and frozen Martian subsurface environment relatively protected from the lethal ionizing radiations.[40]. S1 and S2 isolates have been obtained during normal lab propagation, and R1, R2 and R6 have been obtained after -radiation (see Materials and methods). & Haber, J. E. Sources of DNA double-strand breaks and models of recombinational DNA repair. nov. and Deinococcus gen. nov., including five species. Mol. The mercuric reductase gene has been cloned from Escherichia coli into Deinococcus to detoxify the ionic mercury residue frequently found in radioactive waste generated from nuclear weapons manufacture. In the final step, there is crossover by means of RecA-dependent homologous recombination.[18]. Even though reported characteristics of A-EJ best match the observations, additional work is needed to delineate possible functional overlaps or cross-talk with other DNA repair mechanisms, and identify enzymatic functions involved. Google Scholar. Plasmids dont carry essential genes, by definition59. In recA mutants, such ends could be directed toward non-homologous (illegitimate) recombination pathways. Several explanations might account for the recurrence of deletions within a similar region of chromosome II. Cleanrooms and controlled environments are used for ultraclean conditions in research and manufacturing. Enter your information below. However, even a very large (e.g. A nanotechnological application of D. radiodurans in the synthesis of silver[36] and gold[37] nanoparticles has also been described. Kouzminova, E. A., Rotman, E., Macomber, L., Zhang, J. Radiation-resistant; withstands 6 x 106 rep. Purified genomic DNA of this strain is available as ATCC13939D-5. UniProt We only provide this product sheet to customers who have purchased this biosafety level 3 product. Protein Pept. 27, 722736 (2017). Xu, G. et al. Deinococcus radiodurans recovered after 1 year of exposure to LEO. CAS It can withstand severe dehydration, cold, vacuum, acid, lack of nutrition, and survive to the radiation dose, a fraction of which is sufficient to kill the human being. Bacteria belonging to the family Deinococcaceae are some of the most radiation-resistant organisms discovered, and they are vegetative, easily cultured, and nonpathogenic (23, 137, 138).Despite their ubiquitous distribution and apparent ancient derivation, only seven species of Deinococcaceae have been described (69, 138, 145). The certificate of analysis for that lot of Deinococcus radiodurans (ex Raj et al.) To support this hypothesis, she performed an experiment in which she demonstrated that mutant strains of D. radiodurans that are highly susceptible to damage from ionizing radiation are also highly susceptible to damage from prolonged desiccation, while the wild-type strain is resistant to both. Despite the strong oxidative stress protection, it is possible that proteins of D. radiodurans are adversely affected at the dose as high as 25kGy, or that the ESDSA proteins (including RecA) are saturated by the numerous DSBs10, as the number of DSBs grows proportionally with the radiation dose. Such precision of DNA end joining is therefore more compatible with a SSA-like mechanism. 18, 495506 (2017). In the biomedical field, Deinococcus radiodurans could be used as a model to study the processes that lead to aging and cancer. 181, 666669 (1999). The extraordinary resistance of Deinococcus radiodurans to ionizing radiation (IR) and desiccation is slowly drawing more intense scrutiny. Indeed, the experiments with recA mutants carrying various genetically engineered reporter systems with repetitive sequences have provided strong evidence for SSA as a major RecA-independent mechanism of DSB repair in D. radiodurans12,16,17. Genome of the extremely radiation-resistant bacterium Deinococcusradiodurans viewed from the perspective of comparative genomics. Due to the overlap of the deleted chromosomal areas (Fig. Avantor Services provides a wide range of specialized services and digital solutions to help you solve complex challenges. Nothing that happens in the labor other workplace is as important as your health and safety. Each of the five resulting sequences carrying the in silico deletion was aligned to the one obtained by sequencing and assembling the corresponding recA isolate.

Rising from the Ashes: DNA Repair in Deinococcus radiodurans Notably, all the large deletions we detected in the five recA isolates occur in the chromosome II of D. radiodurans (Fig. 3, 882892 (2005). NHEJ is one of the major pathways that repairs DSBs in eukaryotes but has also been found to operate in some prokaryotes, including Mycobacteria and Bacillus subtilis20. Get what matters in translational research, free to your inbox weekly. Deinococcus radiodurans - an overview | ScienceDirect Topics It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. Thirdly, the recurring deletions could be mechanistically driven, by e.g. We confirmed it was short exact repeats at deletion breakpoints as opposed to slightly longer inexact repeats by comparing the expected breakpoint sequences with the actual breakpoint sequences of recA isolates. Indeed, the D. radiodurans genome does not lack repetitive sequences when compared to genetically close, non-radiation-resistant species7, being rich in both insertions sequences and also in shorter repeats8,9. Deinococcus radiodurans - Wikipedia A strong, vibrant research and development group is the lifeblood of all industries. Le, D. et al. When NHEJ involves homologies, they are usually up to 4bp long, which is the length range that marginally overlaps with length range of repeats identified in this work. For more information, call 1.888.793.2300. The genome rearrangements visible in the PFGE gels were identified as large deletions in chromosome II; each recA isolate carries a deletion spanning 8.621.3% of chromosome II (Table 1), a notable loss of coding DNA sequence. [16], Deinococcus accomplishes its resistance to radiation by having multiple copies of its genome and rapid DNA repair mechanisms. Provided by the Springer Nature SharedIt content-sharing initiative. This Bacterium Survived on The Outside of The Space - ScienceAlert For example, there are 6 SNPs identified by comparison to the reference wt that are common to all the analysed recA isolates (Table S4), but their effect on phenotype is not known. CAS The directionality found within our assembly of chromosome I is supported by the corresponding sequences within chromosomes I from wt-1999 and wt-2016 (checked with Blast). To download a certificate of analysis for Deinococcus radiodurans (ex Raj et al.) Although this contribution might appear negligible compared to that of the RecA-dependent repair mechanisms, the A-EJ pathway may provide a significant add to the survival kit of D. radiodurans, especially when combined with an effective antioxidation protein-protection that is also present in this bacterium23,24,25. 5, a012740 (2013).

PubMed Central %GC at 3rd sites of fourfold degenerate amino acids) of the genome regions. COG categorization of genes46 was obtained from the RefSeq ptt file. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. How is savings calculated?We 5, e92 (2007). Article Deinococcus radiodurans (ex Raj et al.) Brooks and Murray - 13939 - ATCC [24] However, apart from its resistance to radiation, Deinococcus is genetically and biochemically very similar to other terrestrial life forms, arguing against an extraterrestrial origin not common to them. The Deinococcus radiodurans bacterium, characterized by its extreme radioresistance, is also naturally competent. Known repetitive sequences were searched for at the rearrangement breakpoint areas. Nat. To simplify subsequent genome comparisons, some of our genome elements, as well as the genome elements from wt-2016 were rewritten as their reverse complement to achieve the same directionality as the wt-1999 sequences. BLAST+: Architecture and applications. Biochemical characterization of two DNA ligases from Deinococcusradiodurans. performed experiments; J.R., I.S. & Tomkinson, A. E. Repair of DNA double-strand breaks by mammalian alternative end-joining pathways. Genome sequence of the radioresistant bacterium Deinococcusradiodurans R1. Nat. Avantor helps keep you safe with a robust line of safety products and personal protective equipment -- from waste bins to safety signs. 7, 362365 (1999). A rearranged isolate R6 was obtained with the same protocol as R1 and R2, from the N1 strain. Genome rearrangements, except for inversions symmetrical around the ori-ter axis31, are expected to be deleterious in prokaryotes due to the disruption of genome organization32,33. If you find something abusive or that does not comply with our terms or guidelines please flag it as inappropriate. after acute -radiation that resulted in isolates R1, R2 and R6) is more likely to affect chromosomes than plasmids, due to their size. [3] The sequenced strain was ATCC BAA-816. Moreover, a gene encoding a non-specific acid phosphatase from Salmonella enterica, serovar Typhi,[32] and the alkaline phosphatase gene from Sphingomonas[33] have been introduced in strains of D. radiodurans for the bioprecipitation of uranium in acid and alkaline solutions, respectively. Open vial according to enclosed instructions. Additionally, the contig tig00000003 from isolate R1 is only weakly supported by datait is based on 5 PacBio reads. 35, W132W136 (2007). Your session has expired. This also held true for some wt-2016 genome elements. Pannunzio, N. R., Watanabe, G. & Lieber, M. R. Nonhomologous DNA end-joining for repair of DNA double-strand breaks. The choice of repeats as substrates for DNA repair did not depend on the repeat nucleotide sequence; very different repeats were used for DNA repair in different rearrangement events (Table 2). A gene was described that increases nitric oxide production after UV radiation, and in the absence of this gene, the bacteria were still able to repair DNA damage, but would not grow. [26] In addition to DNA repair, D. radiodurans use LEA proteins (Late Embryogenesis Abundant proteins)[27] expression to protect against desiccation. 1992.

They translated the song "It's a Small World" into a series of DNA segments 150 base pairs long, inserted these into the bacteria, and were able to retrieve them without errors 100 bacterial generations later. So much has changed during this unprecedented time, except your ability to count on Avantor. The Canu contigs corresponding to the D. radiodurans genome elements were not circularized by the assemblerthe beginning of the sequence was repeated at the end of the contig (except for the plasmid MP1 from isolate R6). Vertical dashed lines correspond to the deletion borders identified in recA assemblies when compared to reference wt (bp coordinates in Table 2). Our previous and present results are the first to demonstrate large DNA rearrangements involving only genome sequences naturally present in D. radiodurans cells (Repar et al. Are you sure you don't want to sign up to get news from ATCC? 199936 (wt-1999) and Hua and Hua 201637 (wt-2016) were used for comparisons throughout the paper (Table 1). You can select and customize services for peak efficiency, quality, and accelerated innovation. Gene 336, 2535 (2004). 20, 23292330 (2004). Proteinase K solution (0.8mg/ml proteinase K, 2% SDS, 0.1M EDTA) was added next, followed by vortexing and incubation for 3h at 50C. " Deinococcus radiodurans can survive doses of ionising radiation thousands of times stronger than would kill a human.
