Structure of beta-hexosaminidase from Vibrio choleraeStructure of beta-hexosaminidase from Vibrio cholerae

Structural highlights

1tr9 is a 1 chain structure with sequence from "bacillo_virgola_del_koch"_trevisan_1884 "bacillo virgola del koch" trevisan 1884. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
NonStd Res:
Gene:Name=nagZ; OrderedLocusNames=VC0692; ("Bacillo virgola del Koch" Trevisan 1884)
Activity:Beta-N-acetylhexosaminidase, with EC number 3.2.1.52
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

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
