Protein
Beta-hexosaminidase
Gene
nagZ, c1380
Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Hydrolysis of terminal non-reducing N-acetyl-D-hexosamine residues in N-acetyl-beta-D-hexosaminides.UniRule annotation
