Description générale

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.

Actions biochimiques/physiologiques

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.

Définition de l'unité

One unit will conjugate 1.0 μmole of 1-chloro-2,4-dinitrobenzene with reduced glutathione per min at pH 6.5 at 25°C.

Forme physique

Lyophilized powder containing Tris, reduced glutathione and EDTA.

Remarque sur l'analyse

Protein determined by biuret.
Purified and assayed by a modification of the method of Simons and Vander Jagt.
Enzymatic activities are based on the conjugation of reduced glutathione with a second substrate. The individual proteins generally have activity with more than one class of substrate.
