谷胱甘肽S-轉移酶（GSTS）是一個酶家族，通過催化許多疏水性和親電性化合物與還原性谷胱甘肽的結合，在解毒過程中發(fā)揮重要作用。根據其生化、免疫和結構特性，可溶性GST可分為4大類：α、μ、π和θ。GST家族成員是一個多態(tài)基因，編碼活性的、功能不同的GSTP1變異蛋白，被認為在異種代謝中起作用，并在癌癥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.
