CC -!- FUNCTION: Murein endopeptidase that cleaves the D-alanyl-meso-2,6-
CC diamino-pimelyl amide bond that connects peptidoglycan strands. Likely
CC plays a role in the removal of murein from the sacculus.
CC {ECO:0000255|HAMAP-Rule:MF_01623}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01623};
CC Note=Binds 2 Zn(2+) ions per subunit. Zn(2+) ion 1 is bound in the
CC active site. Zn(2+) ion 2 is bound at the dimer interface by residues
CC from both subunits. {ECO:0000255|HAMAP-Rule:MF_01623};
CC -!- SUBUNIT: Dimer. {ECO:0000255|HAMAP-Rule:MF_01623}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_01623}.
CC -!- SIMILARITY: Belongs to the peptidase M74 family. {ECO:0000255|HAMAP-
CC Rule:MF_01623}.
