1 The localization of gamma-glutamyl transferase (GGT) in the intact rat liver was studied by a new approach in which the chromogenic gamma-glutamyl donor substrate of GGT gamma-glutamyl-p-nitroanilide is perfused through the portal vein to yield p-nitroaniline, which is monitored spectrophotometrically. 4-nitroaniline gamma-glutamyltransferase 1 Rattus norvegicus

3 Infusion of glutathione (GSH), the natural substrate of GGT, was shown to markedly reduce or to abolish the formation of p-nitroaniline without entering the liver cells, indicating the existence of a GGT ectoactivity accessible to the sinusoidal circulation. 4-nitroaniline gamma-glutamyltransferase 1 Rattus norvegicus
