Protein

Beta-hexosaminidase

Gene

nagZ

Organism
Escherichia coli (strain ATCC 8739 / DSM 1576 / Crooks)
Status
Reviewed - Annotation score: 3 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.UniRule annotation

Catalytic activityi

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