RESUMO

In 9 of 20 conjugative plasmids of different incompatibility groups, including F and R100 (or R6-5), coexist two sequences which are homologous, respectively, to the gene psiB, which encodes an inhibitor of SOS induction, and to the gene ssb, which encodes a single-stranded-DNA-binding protein.
