Function and Biology Details

Reaction catalysed:
Hydrolysis of gamma-D-glutamyl bonds to the L-terminus (position 7) of meso-diaminopimelic acid (meso-A(2)pm) in 7-(L-Ala-gamma-D-Glu)-meso-A(2)pm and 7-(L-Ala-gamma-D-Glu)-7-(D-Ala)-meso-A(2)pm. It is required that the D-terminal amino and carboxy groups of meso-A(2)pm are unsubstituted.
