3.4.19.11

Accepted name:

γ-D-glutamyl-meso-diaminopimelate peptidase

Reaction:

Hydrolysis of γ-D-glutamyl bonds to the L-terminus (position 7) of meso-diaminopimelic acid (meso-A2pm) in 7-(L-Ala-γ-D-Glu)-meso-A2pm and 7-(L-Ala-γ-D-Glu)-7-(D-Ala)-meso-A2pm. It is required that the D-terminal amino and carboxy groups of meso-A2pm are unsubstituted

Other name(s):

endopeptidase I; γ-D-glutamyldiaminopimelate endopeptidase; γ-D-glutamyl-L-meso-diaminopimelate peptidoglycan hydrolase; γ-glutamyl-L-meso-diaminopimelyl endopeptidase; γ-D-glutamyl-meso-diaminopimelate endopeptidase; γ-D-glutamyl-meso-diaminopimelic peptidoglycan hydrolase; γ-D-glutamyl-meso-diaminopimelic endopeptidase; γ-D-glutamyl-meso-D-aminopimelic endopeptidase

Comments:

A 45-kDa metallopeptidase from Bacillus sphaericus, the substrates being components of the bacterial spore wall. A member of peptidase family M14 (carboxypeptidase A family). Endopeptidase II has similar activity, but differs in cellular location, molecular mass and catalytic mechanism [3]
