GST or Glutathione S-transferase is an enzyme family known for detoxifying endogenous and exogenous compounds through conjugation with glutathione. GSTs are about 23–28 kDa in size and are expressed in various tissues such as the liver kidneys and lungs. The GST proteins play vital roles in cellular processes and are utilized extensively in molecular biology often tagged to proteins to enhance solubility known as GST-tagged proteins.

Biological function summary

GST enzymes participate in critical cellular detoxification processes enhancing the solubility of toxins. As part of these processes GST enzymes do not function as part of a larger complex but are individual actors within the cell. They facilitate the conjugation reactions fundamental to cellular metabolism and detoxification making them essential for maintaining cellular health.

Pathways

GST enzymes contribute significantly to the metabolic breakdown pathways like the xenobiotic metabolism pathway. This pathway involves proteins such as cytochrome P450 enzymes which often function upstream to modify compounds for further GST action. GSTs are important for efficiently detoxifying potentially harmful substances preventing cellular damage.

GSTs have considerable relevance to cancer where their overexpression can confer drug resistance in tumor cells complicating treatment approaches. Additionally these enzymes connect with proteins such as MDR1 influencing multidrug resistance in cancer therapy. GSTs also relate to asthma where altered GST activity can affect the body's response to oxidative stress highlighting the enzyme's role in inflammatory processes.
