The genetic platforms of Deinococcus species remain the only systems in which massive ionizing radiation (IR)-induced genome damage can be investigated in vivo at exposures commensurate with cellular survival. We report the whole genome sequence of the extremely IR-resistant rod-shaped bacterium Deinococcus ficus KS 0460 and its phenotypic characterization. Deinococcus ficus KS 0460 has been st...
Bacteria of the genus Deinococcus are extremely resistant to ionizing radiation (IR), ultraviolet light (UV) and desiccation. The mesophile Deinococcus radiodurans was the first member of this group whose genome was completely sequenced. Analysis of the genome sequence of D. radiodurans, however, failed to identify unique DNA repair systems. To further delineate the genes underlying the resista...
Deinococcus wulumuqiensis R12, isolated from radiation-polluted soil, is a red-pigmented strain of the extremely radioresistant genus Deinococcus. It contains a major carotenoid, namely, deinoxanthin. Here, we present a 3.39-Mb assembly of its genome sequence, which might provide various kinds of useful information related to Deinococcus, such as about the key enzymes of its radioresistance mec...
Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...
The Deinococcus radiodurans bacterium is extremely resistant to ionising radiation and desiccation and can withstand a 200-fold higher radiation dose than most other bacteria with no loss of viability. The mechanisms behind this extreme resistance are not fully understood, but it is clear that several factors contribute to this phenotype. Efficient scavenging of reactive oxygen species and repa...
With the aim of engineering a strain of bacteria that could be used for bioremediation of cellulosic waste in radioactive environments, the gene for the secreted endoglucanase enzyme of Bacillus pumilis was decided to be cloned into the radiotolerant bacterium, Deinococcus radiodurans. The endoglucanase gene from B. pumilus was PCR amplified and cloned into Escherichiacoli DH5α using a pDrive v...
The complete genome sequence of the radiation-resistant bacterium Deinococcus radiodurans R1 is composed of two chromosomes (2,648,638 and 412,348 base pairs), a megaplasmid (177,466 base pairs), and a small plasmid (45,704 base pairs), yielding a total genome of 3,284, 156 base pairs. Multiple components distributed on the chromosomes and megaplasmid that contribute to the ability of D. radiod...
Deinococcus radiodurans R1 (DEIRA) a member of Deinococcae family can survive ~12 kGy dose of γ radiation which can generate about 200 double strands and 3000 single strand breaks per genome. An efficient DNA strand break repair, contributes maximum to the radioresistance of Deinococcus radiodurans. Distinction in DNA strand break repair from others seems to lie in the mechanism of action of DN...
The genome sequence of Deinococcus radiodurans R1 was published in 1999. We resequenced D. radiodurans R1 using PacBio and compared the sequence with the published one. Large insertions and single nucleotide polymorphisms (SNPs) were observed among the genome sequences. A more accurate genome sequence will be helpful to studies of D. radiodurans.
Deinococcus radiodurans shows remarkable resistance to reactive oxygen species (ROS), generated by irradiation. Disruption of recX (dr1310) in D. radiodurans using targeted mutagenesis method enhanced its ROS scavenging activity, and recX overexpression in this bacterium repressed its antioxidant activity significantly. Further analyses on catalase and superoxide dismutase, two important antiox...
