the results indicate that the preferred route for gssg metabolism to the constituent amino acids in small intestine , is by hydrolytic removal of the two gamma-glutamyl groups of gssg to yield cystinyl-bisglycine which is subsequently hydrolyzed to cystine . gamma-glutamyltransferase activity was compared in isolated intestinal , kidney and liver cells using gamma-glutamyl-p-nitrocarboxyanilide as substrate .
