After the plasma membrane carrier-mediated GSH release from the cell, GSH becomes accessible to the active site of - glutamyl transpeptidase, which catalyzes the breakdown of the GSH - glutamyl bond forming two fractions: The -glutamyl fraction and the cysteinyl-glycine by transferring the -glutamyl fraction to an amino acid acceptor, forming -glutamyl-amino acid
The peptide comes in a lyophilized (freeze-dried) form, which needs to be reconstituted with sterile water
