谷胱甘肽S-转移酶（GSTS）是一个酶家族，通过催化许多疏水性和亲电性化合物与还原性谷胱甘肽的结合，在解毒过程中发挥重要作用。根据其生化、免疫和结构特性，可溶性GST可分为4大类：α、μ、π和θ。GST家族成员是一个多态基因，编码活性的、功能不同的GSTP1变异蛋白，被认为在异种代谢中起作用，并在癌症和其他疾病的易感性中起作用。
Glutathione S-transferases (GSTs) are a family of enzymes that play an important role in detoxification by catalyzing the conjugation of many hydrophobic and electrophilic compounds with reduced glutathione. Based on their biochemical, immunologic, and structural properties, the soluble GSTs are categorized into 4 main classes: alpha, mu, pi, and theta. This GST family member is a polymorphic gene encoding active, functionally different GSTP1 variant proteins that are thought to function in xenobiotic metabolism and play a role in susceptibility to cancer, and other diseases.
