An alternative pathway of recombination of chromosomal fragments precedes recA-dependent recombination in the radioresistant bacterium Deinococcus radiodurans.

Abstract excerpt

Deinococcus radiodurans R1 and other members of this genus are able to repair and survive extreme DNA damage induced by ionizing radiation and many other DNA-damaging agents. The ability of R1 to repair completely > 100 double-strand breaks in its chromosome without lethality or mutagenesis is recA dependent. However, during the first 1.5 h after irradiation, recA+ and recA cells show similar increases in the...
