Abstract

Inducible stable DNA replication (iSDR) is dependent on recombination and is supposed to play a role in DNA repair of Escherichia coli. Our previous data suggested that iSDR may be involved in the tolerance of UV lesions, which remain unexcised in excision-proficient E. coli exposed to some UV pretreatments. Now, the tolerance of unexcised lesions has been followed in E. coli recB21 and in E. coli priA1 sop mutants, incapable of iSDR. The obtained data do not confirm the previous hypothesis about the involvement of iSDR in the putative uvrdependent lesion tolerance. They rather suggest that iSDR and the uvr-dependent lesion tolerance are two uncoupled processes. (C)2000 Elsevier Science S.A. All rights reserved.
