  • Monobromobimane (mBBr), functions as a substrate of porcine glutathione S‐transferase π (GST π): The enzyme catalyzes the reaction of mBBr with glutathione. S‐(Hydroxyethyl)bimane, a nonreactive analog of monobromobimane, acts as a competitive inhibitor with respect to mBBr as substrate but does not affect the reaction of GST π with another substrate, 1‐chloro‐2,4‐dinitrobenzene (CDNB). In the absence of glutathione, monobromobimane inactivates GST π at pH 7.0 and 25°C as assayed using mBBr as… CONTINUE READING
