Previously we reported the purification of soluble γ-glutamyltransferases (GGTs) from radish cotyledon. Subcellular fractionation of radish cells revealed that soluble GGT is a vacuolar enzyme. Acivicin, a GGT inhibitor, mediated the <I>in vivo</I> catabolism inhibition of the glutathione <I>S</I>-conjugate generated from endogenous glutathione and exogenously supplied monochlorobimane. Thus soluble GGT is possibly involved in the catabolism of glutathione <I>S</I>-conjugates.
