Abstract excerpt

Suppression of leu-500 mutation in Salmonella typhimurium topA- strains has been one of the most fascinating examples for the DNA supercoiling effect on transcription initiation control. Previous studies have indicated possible involvement of transcription-driven DNA supercoiling in the activatio...
