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). Hydrolyzes rapidly p-nitrophenyl-N-acetyl-beta-D-glucosaminide (PNP-beta-GlcNAc) and 4-methylumbelliferyl-beta-GlcNAc, and slightly active on p-nitrophenyl-beta-GalNAc. May play a role in signal transduction between host and organism.1 PublicationUniRule annotation
