Abstract

An exonuclease III-deficient strain of Escherichia coli K-12, BW2001 (xthA11), was unable to perform rapid repair of X-ray-induced deoxyribonucleic acid single-strand breaks and appeared to have a defect in the priming of the 3'-termini necessary for initiation of repair synthesis at the breaks. This defect cannot be explained solely by the lack of exonuclease III activity, because other xth mutants tested, including a deletion mutant, repaired radiation-induced strand breaks at close to the normal rate.
