Accepted name: D-glutamyltransferase
Reaction: (1) D-glutamine + D-glutamate = NH3 + γ-D-glutamyl-D-glutamate
(2) L(or D)-glutamine + (γ-D-glutamyl)n-[peptide] = NH3 + (γ-D-glutamyl)n+1-[peptide]
Other name(s): D-glutamyl transpeptidase; D-γ-glutamyl transpeptidase
Systematic name: glutamine:D-glutamyl-peptide 5-glutamyltransferase
Comments: The enzyme catalyses two reactions. The first is the transfer of a glutamyl residue from L- or D-glutamine to D-glutamate via a γ linkage, forming γ-glutamyl-D-glutamate, and the second is the transfer of additional glutamyl residues to the peptide, extending the polypeptide chain.
