The enzyme γ-glutamyl transpeptidase (GGT), implicated in many physiological processes, catalyses the transfer of a γ-glutamyl from a donor substrate to an acyl acceptor substrate, usually an amino acid or a peptide. In order to investigate which moieties of the donor substrate are necessary for recognition by GGT, the structure of the well-recognized substrate l-γ-glutamyl-p-nitroanilide was modified. Several activated esters and their ...
