CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of (1->4)-beta-linkages between N-acetylmuramic
CC         acid and N-acetyl-D-glucosamine residues in a peptidoglycan and
CC         between N-acetyl-D-glucosamine residues in chitodextrins.;
CC         EC=3.2.1.17;
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- MISCELLANEOUS: Shows preference for N-acetylmuramic acid residues that
CC       are substituted with a peptide moiety. It acts only as a
CC       glycanohydrolase (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 23 family. {ECO:0000305}.
