Function

NAGZ_VIBCH 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.[1] [2] [3]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
