Glutathione S-transferases are a family of multifunctional enzymes that catalyze the conjugation of the antioxidant glutathione (GSH) to a wide range of electrophilic compounds. This reaction results in the formation of more water-soluble conjugates that can be easily excreted from the body. GSTs are found in various tissues across different species, including humans, and are involved in the phase II metabolism of toxins.
