Glutathione peroxidase ec 1.11.1.9 glutathione reductase ec 1.6.4.2 glutathione s transferase ec 2.5.1.18 and gamma glutamyl trans peptidase ec 2.3.2.2 activities in the human early pregnancy placenta


, : Glutathione peroxidase ec 1.11.1.9 glutathione reductase ec 1.6.4.2 glutathione s transferase ec 2.5.1.18 and gamma glutamyl trans peptidase ec 2.3.2.2 activities in the human early pregnancy placenta. Biochemical Medicine 29(2): 143-148

GSH [glutathione] peroxidase, GSSG [glutathione] reductase, GSH S-transferase, and .gamma.-glutamyltranspeptidase activities were measured in the supernatant of 13 human early pregnancy placenta homogenates. From measurements of GSH peroxidase activity with both H2O2 and cumene hydroperoxide as 2nd substrate, it was deduced that immature placenta contains only the Se-dependent form. All the specimens investigated exhibited GSSG reductase and .gamma.-glutamyltranspeptidase activities. GSH S-transferase activity was noted only using 1-chloro-2,4-dinitrobenzene as electrophilic substrate, while no detectable activity was found with 1,2-dichloro-4-nitrobenzene, 1,2-epoxy-3-(p-nitrophenoxy) propane and p-nitrobenzylchloride. Human placenta is equipped, from early pregnancy, with the enzymatic systems which are involved in GSH-mediated cellular detoxication and in preserving the integrity of the sulfhydryl status of the cells.
