Product Name

Glutathione S-Transferase from equine liver

General deion

Glutathione S-transferase (GST) is a major detoxification enzyme, and exists as multiple cytoplasmic and membrane-bound isozymes. These isozymes differ in their catalytic activity, as well as in their non-catalytic binding properties. Cytoplasmic isoforms of GST are encoded by five genes, namely α, θ, μ, σ and π. α, μ and π are the most abundant forms in mammals. Membrane bound GST forms are encoded by a single gene.

Synonym

GST, Glutathione R-transferase, Glutathione S-alkenetransferase, Glutathione S-alkyltransferase, Glutathione S-aralkyltransferase, Glutathione S-aryltransferase, Glutathione S-epoxidetransferase

l Biological Information

Biochem/Physiol Actions

Glutathione S-transferase (GST) from equine liver has been used-

• as a constituent of Tris buffer for incubation of human umbilical vein endothelial cells (HUVEC) with atracurium to assess the proliferation of HUVEC in the presence of atracurium

• as a component of GSB stock solution to determine GSB (glutathione S-bimane) conjugate fluorescence intensity in intact Arabidopsis cells

• as an enzyme standard in spectrophotometric assay to determine the activity of GST

Glutathione S-transferases are a family of proteins that catalyze the conjugation of reduced glutathione with a variety of hydrophobic chemicals containing electrophilic centers.

Unit Definition
