Protein

Beta-hexosaminidase

Gene

nagZ

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

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. Plays a role in beta-lactam antibiotic resistance via its role in generating anhydro-N-acetylmuramic acid-linked peptides; these peptides function as signaling molecules that induce high-level expression of the beta-lactamase AmpC.2 PublicationsUniRule annotation
