The complete genome sequence of Deinococcus radiodurans R1, a radiation-resistant bacterium, consists of two chromosomes (2,648,615 and 412,340 basepairs), a megaplasmid (177,466 basepairs), and a small plasmid (45,702 basepairs), totaling 3,284,123 basepairs. The genome contains 3,193 open reading frames (ORFs), with 2,192 matching public databases. The genome includes genes for DNA repair, DNA damage export, desiccation and starvation recovery, and genetic redundancy. D. radiodurans is highly resistant to ionizing radiation and UV light, with cells 200-fold more resistant to ionizing radiation and 20-fold more resistant to UV than E. coli. The genome was sequenced using the random whole genome shotgun method. The genome is composed of four circular molecules: chromosome I, chromosome II, a megaplasmid, and a plasmid. The genome contains a nearly full suite of DNA repair activities, including nucleotide excision repair, base excision repair, mismatch excision repair, and recombinational repair. The genome also includes genes for amino acid utilization, cell envelope formation, and transporters, indicating chromosome II is likely essential. The genome contains 3,193 ORFs, with 2,192 matching public databases. The genome includes 1,665 genes placed into 95 families, with the P-loop nucleotide binding proteins and helix-turn-helix family being the largest. Phylogenetic studies suggest that Deinococci are closely related to the Thermus genus. The genome contains genes for DNA repair, DNA damage export, desiccation and starvation recovery, and genetic redundancy. The genome also includes genes for the production of ammonia, amino acids, and energy generation. The genome contains genes for the production of ammonia, amino acids, and energy generation.
