if a similar enzyme distribution should exist in vivo in the bicellular layer of ciliary epithelium , the present result suggests that both npe and pe cells are involved in the detoxification of xenobiotics via the mercapturate pathway , glutathione conjugation occurring primarily in the pe cells and the reactions catalyzed by the membrane-bound enzymes gamma-glutamyl transpeptidase and n-acetyl transferase taking place mainly in the npe cells .
