Roles of human sulfotransferases in genotoxicity of carcinogens using genetically engineered umu test strains.

Human sulfotransferase (SULT) 1A1, 1A2, and 1A3 cDNA genes were subcloned separately into the pTrc99A(KM) vector. The generated plasmids were introduced into the Salmonella typhimurium O-acetyltransferase-deficient strain NM6000 (TA1538/1,8-DNP/pSK1002), resulting in the new strains NM7001, NM7002, and NM7003. We compared the sensitivities of these three strains with the parental strain NM7000 ...
