Escherichia coli merodiploids with altered ratios of episomal to chromosomal RNA polymerase activity.

I P Tittawella.   

Abstract

Starting with an E. coli merodiploid strain (rpoB+ (rifS)/rpoB- (rifR)) containing equal amounts of rifampicin-sensitive and resistant RNA polymerase activities, mutants were isolated that had a disproportionately high ratio of the rifampicin-resistant enzyme activity. With one strain it is shown that the mutation responsible for this phenotype is closely linked to the rifR (rpoB-) allele.
