RESUMO
Escherichia coli mukF, mukE, and mukB null mutants have common phenotypes such as temperature-dependent colony formation, anucleate cell production, chromosome cutting by septum closure, and abnormal localization of SeqA-DNA clusters. We show here that the associated muk null mutations cause hypersensitivity to novobiocin. Null mutation of either dam or seqA suppressed partially the temperature-sensitive lethality but failed to suppress the anucleate cell production and the hypersensitivity to novobiocin caused by muk null mutations.
