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       {ECO:0000255|HAMAP-Rule:MF_00364}.
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:0000255|HAMAP-Rule:MF_00364};
CC   -!- PATHWAY: Cell wall biogenesis; peptidoglycan recycling.
CC       {ECO:0000255|HAMAP-Rule:MF_00364}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00364}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 3 family. NagZ subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00364}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAJ23017.1; Type=Erroneous initiation; Evidence={ECO:0000305};
