Comments [?]

Function Involved in muropeptide degradation. Catalyzes the hydrolysis of the gamma-D-glutamyl-diaminopimelic acid (gamma-D-Glu-Dap) amide bond in the murein tripeptide L-alanyl-gamma-D-glutamyl-meso-diaminopimelic acid, leading to the formation of L-Ala-gamma-D-Glu and Dap.
Catalytic activity RHEA:28398: H2O + L-alanyl-gamma-D-glutamyl-meso-diaminoheptanedioate = L-alanyl-D-glutamate + meso-2,6-diaminoheptanedioate
case <FTGroup:1>
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
end case
Pathway Cell wall degradation; peptidoglycan degradation.
Subunit Homodimer.
Subcellular location Cytoplasm.
Similarity Belongs to the peptidase M14 family.
