The budding yeast Saccharomyces cerevisiae and the fission yeast Schizosaccharomyces pombe are both sensitive to camptothecin, an inhibitor of DNA topoisomerase I. An S. cerevisiae DNA repair mutant, rad52, is hypersensitive to the drug. In both species, topoisomerase I mutants totally lacking the enzyme are completely resistant to the drug. A strain with a mutation leading to a temperature-sensitive topoisomerase I exhibits temperature dependence in its in vivo response to camptothecin. A… CONTINUE READING
