1 It has been postulated that bleomycin hydrolase, a protease encoded by the BLH1 gene in humans, may account for tumor resistance to bleomycin. Bleomycin bleomycin hydrolase Saccharomyces cerevisiae S288C
2 In support of such a notion, earlier studies showed that exogenous expression of yeast Blh1 in human cells can enhance resistance to bleomycin. Bleomycin bleomycin hydrolase Saccharomyces cerevisiae S288C
3 Here we show that (i) yeast blh1delta mutants are not sensitive to bleomycin, (ii) bleomycin-hypersensitive yeast mutants were no more sensitive to this agent upon deletion of the BLH1/LAP3/GAL6 gene, and (iii) overproduction of Blhl in either the parent or bleomycin-hypersensitive mutants did not confer additional resistance to these strains. Bleomycin bleomycin hydrolase Saccharomyces cerevisiae S288C
4 Here we show that (i) yeast blh1delta mutants are not sensitive to bleomycin, (ii) bleomycin-hypersensitive yeast mutants were no more sensitive to this agent upon deletion of the BLH1/LAP3/GAL6 gene, and (iii) overproduction of Blhl in either the parent or bleomycin-hypersensitive mutants did not confer additional resistance to these strains. Bleomycin bleomycin hydrolase Saccharomyces cerevisiae S288C
5 Here we show that (i) yeast blh1delta mutants are not sensitive to bleomycin, (ii) bleomycin-hypersensitive yeast mutants were no more sensitive to this agent upon deletion of the BLH1/LAP3/GAL6 gene, and (iii) overproduction of Blhl in either the parent or bleomycin-hypersensitive mutants did not confer additional resistance to these strains.

6 Here we show that (i) yeast blh1delta mutants are not sensitive to bleomycin, (ii) bleomycin-hypersensitive yeast mutants were no more sensitive to this agent upon deletion of the BLH1/LAP3/GAL6 gene, and (iii) overproduction of Blhl in either the parent or bleomycin-hypersensitive mutants did not confer additional resistance to these strains. Bleomycin bleomycin hydrolase Saccharomyces cerevisiae S288C
7 Here we show that (i) yeast blh1delta mutants are not sensitive to bleomycin, (ii) bleomycin-hypersensitive yeast mutants were no more sensitive to this agent upon deletion of the BLH1/LAP3/GAL6 gene, and (iii) overproduction of Blhl in either the parent or bleomycin-hypersensitive mutants did not confer additional resistance to these strains.
