Glutathione metabolism and transport in the choroid plexus were probed by determining the effects of administration to rats of several compounds (buthionine sulfoximine, L-2-oxothiazolidine-4-carboxylate, L-(alpha 5,5S)-alpha-amino-3-chloro-4,5-dihydro-5-isoxazole acetic acid, gamma-glutamyl alanine, and glutathione monoethyl ester) on the levels of glutathione and

gamma-Glutamyl cyclotransferase activity is assayed in tissues by a colorimetric method using gamma-glutamyl alanine as a substrate coupled with alanine dehydrogenase from B. sphericus, to measure the formation of NADH. In order to avoid interference by the reaction catalyzed by

Spin-echo NMR spectroscopy was used to record the cleavage of a gamma-glutamyl--amino-acid by (5-L-glutamyl)-L-amino-acid 5-glutamyltransferase (cyclizing) (gamma-glutamylcyclotransferase) in human erythrocyte hemolysates. The Michaelis-Menten steady-state kinetic parameters were obtained by fitting the integrated Michaelis-Menten equation to the reaction time curves. The
