The dif resolvase locus of the Escherichia coli chromosome can be replaced by a 33-bp sequence, but function depends on location.

Abstract excerpt

The dif locus (deletion-induced filamentation) of Escherichia coli is a resolvase site, located in the terminus region of the chromosome, that reduces chromosome multimers to monomers. In strains in which this site has been deleted, a fraction of the cells is filamentous, has abnormal nucleoid structure, and exhibits elevated levels of the SOS repair system. We have demonstrated that a 33-bp sequence, which is...
