Abstract excerpt
Mutations affecting DNA topoisomerase I (topA) in Salmonella typhimurium were isolated and graded on the basis of their ability to reverse the effects of gyrB mutations on his operon expression. Different topA and gyrB alleles (in otherwise isogenic strains) were used to gather insights into the...
