Transpeptidase may refer to:
*
DD-transpeptidase
DD-transpeptidase (, ''DD-peptidase'', ''DD-transpeptidase'', ''DD-carboxypeptidase'', ''D-alanyl-D-alanine carboxypeptidase'', ''D-alanyl-D-alanine-cleaving-peptidase'', ''D-alanine carboxypeptidase'', ''D-alanyl carboxypeptidase'', and ''serine-t ...
, a bacterial enzyme that cross-links the peptidoglycan chains to form rigid cell walls

Gamma-glutamyl transpeptidase
Gamma-glutamyltransferase (also γ-glutamyltransferase, GGT, gamma-GT, gamma-glutamyl transpeptidase; ) is a transferase (a type of enzyme) that catalyzes the transfer of gamma- glutamyl functional groups from molecules such as glutathione to ...
, a liver enzyme
*
D-glutamyl transpeptidase
In enzymology, a D-glutamyltransferase () is an enzyme that catalyzes the chemical reaction
:L(or D)-glutamine + D-glutamyl-peptide \rightleftharpoons NH3 + 5-glutamyl-D-glutamyl-peptide
The 3 substrates of this enzyme are L-glutamine, D-glut ...

protein-sorting transpeptidase A protein-sorting transpeptidase is an enzyme, such as the sortase SrtA of Staphylococcus aureus, that cleaves one or more target proteins produced by the same cell, as part of a specialized pathway of protein targeting. The typical prokaryotic pr ...
(e.g.
sortase
Sortase refers to a group of prokaryote, prokaryotic enzymes that modify surface proteins by recognizing and cleaving a carboxyl-terminal protein targeting, sorting signal. For most substrates of sortase enzymes, the recognition signal consists o ...
), that cleaves a C-terminal sorting signal from its target protein(s) and then covalently attaches the remainder to the cell surface.
