General annotation (Comments)

Function

Plays a role in peptidoglycan recycling by cleaving the terminal beta-1,4-linked N-acetylglucosamine (GlcNAc) from peptide-linked peptidoglycan fragments, giving rise to free GlcNAc, anhydro-N-acetylmuramic acid and anhydro-N-acetylmuramic acid-linked peptides By similarity. HAMAP-Rule MF_00364

Catalytic activity

Hydrolysis of terminal non-reducing N-acetyl-D-hexosamine residues in N-acetyl-beta-D-hexosaminides. HAMAP-Rule MF_00364

Pathway

Cell wall biogenesis; peptidoglycan recycling. HAMAP-Rule MF_00364

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00364.

Sequence similarities

Belongs to the glycosyl hydrolase 3 family. NagZ subfamily.

Sequence caution

The sequence AAO29230.1 differs from that shown. Reason: Erroneous initiation.
