Abstract
The exceptional radioresistance of M. radiodurans was lost by a mutation, and the isolated mutant, KH840, had almost the same radiosensitivity as E. coli K12 AB1157 or B/r. DNA-strand scissions in this mutant were rejoined partly during post-irradiation incubation. Reduced DNA polymerizing activity and extensive degradation of the product was observed in vitro in the crude extract from the sensitive strain. The lower repair capability is not accompanied by the reduced transformation frequency.
