The stereoselectivity of the closely related isozymes A2and C2of rat liver glutathione S-transferase toward several arene and azaarene oxides is examined. Isozyme C2is stereospecific, catalyzing attack of glutathione at the oxirane carbon of R absolute configuration for a series of K-region arene oxides including phenanthrene 9,10-oxide,1. Substitution of nitrogen in the biphenyl system of1causes a loss in stereospecificity. Isozyme A2exhibits a low degree of stereoselectivity toward both arene and azaarene oxides. Kinetic studies of the two isozymes show that although isozyme C2turns over1faster than does isozyme A2the opposite is true when 4,5-diazaphenanthrene 9,10-oxide is the substrate. The kinetic and stereochemical behavior of the homodimeric isozymes A2and C2can be used to predict the stereoselectivity of the heterodimeric isozyme AC perhaps suggesting that catalysis is insensitive to different subunit-subunit interactions in the three isozymes.
