Abstract excerpt
The leu-500 mutation is an A-to-G point mutation in the -10 region of the promoter controlling the leuABCD operon of Salmonella typhimurium. Suppression of the leu-500 mutation in an S. typhimurium topA mutant has demonstrated the functional dependency of this mutated promoter on negative superco...
