Glutathione S-transferases (GSTs) previously known as ligandins comprise a family of eukaryotic and prokaryotic phase II metabolic isozymes best known for their ability to catalyze the conjugation of the reduced form of glutathione (GSH) to xenobiotic substrates for the purpose of detoxification. The GST family consists of three superfamilies: the cytosolic mitochondrial and microsomal—also known as MAPEG—proteins.
