Biophys. Res. Commun. 189:173-178(1992). CC -!- CATALYTIC ACTIVITY: (5-L-GLUTAMYL)-PEPTIDE + AN AMINO ACID = CC PEPTIDE + 5-L-GLUTAMYL-AMINO ACID. CC -!- PATHWAY: GGT PLAYS A KEY ROLE IN THE GAMMA-GLUTAMYL CYCLE, A CC PATHWAY FOR THE SYNTHESIS AND DEGRADATION OF GLUTATHIONE. CC -!- SUBUNIT: THIS ENZYME CONSISTS OF TWO POLYPEPTIDE CHAINS, WHICH ARE CC SYNTHESIZED IN PRECURSOR FORM FROM A SINGLE POLYPEPTIDE. CC -!- SUBCELLULAR LOCATION: PERIPLASMIC. CC -!- SIMILARITY: STRONG, TO OTHER GGT ENZYMES AND TO GL-7ACA ACYLASES.
