GLUTATHIONE-MEDIATED DETOXIFICATION SYSTEMS IN PLANTS

Recent work has highlighted the presence of diverse glutathione-depend ent enzymes in plants with potential roles in the detoxification of bo th xenobiotic and endogenous compounds. In particular, studies on glut athione transferases are further characterising their role in xenobiot ic metabolism, and also raising intriguing possible roles in endogenou s metabolism. The solution of their three-dimensional structures toget her with studies on their molecular diversity and substrate specificit y is providing new insights into the function and classification of th ese enigmatic enzymes.
