Genome Sequence of the Radioresistant Bacterium Deinococcus radiodurans R1
Science, 1999•science.org
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. radiodurans to survive under conditions of
starvation, oxidative stress, and high amounts of DNA damage were identified. Deinococcus …
