Suppression of the abnormal phenotype of Salmonella typhimurium rfaH mutants by mutations in the gene for transcription termination factor Rho.

Abstract excerpt

Mutations in the rfaH gene have previously been shown to cause premature termination of transcription of the traYZ operon of the F factor and also to prevent expression of the rfaGBIJ gene cluster of Salmonella typhimurium. In the present study, mutants were selected for their ability to restore the normal pattern of rfaGBIJ function. On the basis of this initial section, several classes of extragenic suppressor...
