A spontaneous Escherichia coli K12 mutant which inhibits the excision-reintegration process of Mu gem2ts.

FEMS microbiology letters - 1 Sept 1997

Abstract excerpt

Escherichia coli K12 strains lysogenic for Mu gem2ts with the prophage inserted in a target gene (i.e., lacZ::Mu gem2ts lysogenic strains) revert to Lac+ by prophage precise excision with a relatively high frequency (about 1 x 10(-6)). The revertants obtained are still lysogens with the prophage inserted elsewhere in the bacterial chromosome. We have observed that, with the time of storage in stabs, bacterial...
