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