Glutathione S-transferases


GST conjugate the tripeptide glutathione to various chemical substrates - often as part of phase II of detoxification. A typical detoxification may involve a P450 adding a hydroxyl group to a substrate (phase I) that then enables a GST to add the glutathione (phase II) which can assist in the excretion of that compound.
