| Description: | The glutathione S-transferase (GST) family of enzymes comprises a long list of cytosolic, mitochondrial, and microsomal proteins that are capable of multiple reactions with a multitude of substrates, both endogenous and xenobiotic. Mammalian cytosolic GSTs are dimeric both subunits being from the same class of GSTs. The monomers are in the range of 22�29 kDa. Glutathione S-transferase is used to create the �GST gene fusion system� in genetic engineering. Here, GST is used to purify and detect proteins of interest. |
