CC   -!- FUNCTION: Plays a role in peptidoglycan recycling by cleaving the
CC       terminal beta-1,4-linked N-acetylglucosamine (GlcNAc) from peptide-
CC       linked peptidoglycan fragments, giving rise to free GlcNAc, anhydro-N-
CC       acetylmuramic acid and anhydro-N-acetylmuramic acid-linked peptides.
CC       Cleaves muropeptides, but not peptidoglycan.
CC       {ECO:0000269|PubMed:20400549, ECO:0000269|PubMed:20826810}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of terminal non-reducing N-acetyl-D-hexosamine
CC         residues in N-acetyl-beta-D-hexosaminides.; EC=3.2.1.52;
CC         Evidence={ECO:0000269|PubMed:20400549, ECO:0000269|PubMed:20826810};
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       pH dependence:
CC         Optimum pH is 5.8-6.2. {ECO:0000269|PubMed:20826810};
CC   -!- PATHWAY: Cell wall biogenesis; peptidoglycan recycling.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|PROSITE-
CC       ProRule:PRU00303}; Lipid-anchor {ECO:0000255|PROSITE-ProRule:PRU00303}.
CC       Secreted, cell wall {ECO:0000269|PubMed:20400549}. Note=Detected in the
CC       culture supernatant, predominantly associated with cell wall-derived
CC       particulate material. A minor proportion is detected in the soluble
CC       fraction.
CC   -!- INDUCTION: Up-regulated during the late phase of exponential growth and
CC       during stationary phase. {ECO:0000269|PubMed:20400549}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 3 family. {ECO:0000305}.
