[Plasmid R1drd-19-mediated superoligomerization of the plasmid pACYC184in the recB mutant of Escherichia coli K12].

Abstract excerpt

It was found that monomers of the pACYC184 plasmid undergo superoligomerization in a recB mutant of Escherichia coli K12 which is deficient in ATP-dependent RecBC nuclease and carries the drug resistance plasmid R1drd-19. The observed effect is specifically related to the ability of R1drd-19 to determine an ATP-dependent exonucleolytic activity which is functionally similar but not identical to the RecBC...
