Abstract

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 λN^- mutants. The relief of the N requirement by this host is reflected in a substantial restoration of growth and N-dependent β-galactosidase expression as well as in a partial relief of polarity of N-defective phages.
