โœฆ Synopsis


A new mutant of bacteriophage P1 designated lxc that suppresses the phenotype of lexC and ssbA mutants of Escheriehia eoli was isolated and characterized. The properties of lexC mutants suppressed by the lxc mutation include temperature sensitive growth at 42 ยฐ C, sensitivity to ultraviolet light and alkylating agents, and a nonmutagenic response following exposure to ultraviolet irradiation. A bac mutant of bacteriophage P1 that suppresses the temperature sensitivity of dnaB mutants does not affect the phenotype of lexC or ssbA mutants. Neither the lxc or bac mutations affect the ultraviolet light sensitivity of strains with the mutations uvrA155, lexAl02, or recA56.

The dasC mutation could not be separated from trxA by P1 transduction indicating that dasC and trxA are allelic. Multicopy plasmids containing an in

The E. coli suA mutant (T82), which is a suppressor of polarity by virtue of its impaired transcription termination factor (rho) activity, is shown to be an efficient suppressor of lambdaN- mutants. The relief of the N requirement by this host is reflected in a substantial restoration of growth and

The presence of the drug resistance plasmid pKM101 restored the ability of Escherichia coli umuC mutant strains to be mutated by methyl methanesulfonate. Inducible (Weigle) reactivation of ultraviolet-irradiated bacteriophage lambda was not observed in uvrA6 umuC mutant strains lacking pKM101 but wa
