Major areas of interest include the metabolism of carcinogens and drugs by cytochrome P450 enzymes, the bioactivation of halogenated hydrocarbons, and polymerase interactions with carcinogen-modified DNA. Several approaches are being used to understand the catalytic mechanisms of the human cytochrome P450 enzymes, including site-directed and random mutagenesis, kinetic analysis, isotope effects, and substrate-activity relationships. Work on halogenated hydrocarbons is done with trichloroethylene, ethylene dibromide, and methylene dihalides and the adducts they form. Glutathione transferase-mediated bioactivation is under investigation, as well as in the case of some bifunctional electrophiles. Studies on the polymerases involve the use of modified oligonucleotides, steady-state and pre-steady-state kinetics, and physical approaches such as x-ray diffraction. A major goal is to understand how carcinogen-DNA adducts cause polymerases to stall and misincorporate bases.
