In enzymology, a D-glutamyltransferase ({{EC number|2.3.2.1}}) is an enzyme that catalyzes the chemical reaction

L(or D)-glutamine + D-glutamyl-peptide NH₃ + 5-glutamyl-D-glutamyl-peptide

The 3 substrates of this enzyme are L-glutamine, D-glutamine, and D-glutamyl-peptide, whereas its two products are NH₃ and 5-glutamyl-D-glutamyl-peptide.

This enzyme belongs to the family of transferases, specifically the aminoacyltransferases. The systematic name of this enzyme class is glutamine:D-glutamyl-peptide 5-glutamyltransferase. Other names in common use include D-glutamyl transpeptidase, and D-gamma-glutamyl transpeptidase. This enzyme participates in d-glutamine and d-glutamate metabolism.
