Glutathione S-transferases are a family of proteins that catalyze the conjugation of reduced glutathione with a variety of hydrophobic chemicals containing electrophilic centers.
GST, Native (Equine)
Lyophilized powder containing Tris and phosphate buffer salts, reduced glutathione and EDTA
Enzyme Commission Number
> 25 units/mg protein
mol wt 45-50 kDa
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.
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.
