Abstract |
Characterization of a Salmonella typhimurium mutant strain (TA98/1,8-DNP6) resistant to the mutagenicity of nitrated polycyclic aromatic hydrocarbons (nitroarenes) revealed that it was also non-responsive to the mutagenic action of nitroso- and N-hydroxylaminoarenes. The mutant strain was fully sensitive to the mutagenic action of the corresponding hydroxamic acid ester. These results suggest that TA98/1,8-DNP6 is deficient in a specific esterifying enzyme and that esterification of the penultimate mutagenic metabolites of nitro- and aminoarenes (e.g., arylhydroxylamines) to form potent electrophiles is controlled by a specific gene. |
