## Abstract γ‐Glutamyl transpeptidase (γ‐GTP) is suggested to act as a carrier in the group translocation of oligopeptides and possibly some amino acids across cellular membranes. It is proposed that the process may involve the repetitive transfer of γ‐glutamyl groups to acceptor peptides which are

The release of newly loaded L-['4C]glutamine (L-Gln) from rat cerebral cortical capillaries was stimulated by L-transport system substrates: tryptophan (TRY), leucine (leu), and nonlabeled L-Gln, respectively, by 32, 50, and 40% above the basal release resulting from superfusion with standard Krebs-
